Summary: “The ICD-10 code family for osteoporosis is M80 (with current pathological fracture) and M81 (without). The M80 vs M81 decision is the first thing a coder must answer.”
Osteoporosis is one of the most common chronic bone conditions in US adults. The Centers for Disease Control and Prevention (CDC) NHANES data shows that 12.6% of US adults aged 50 and over have osteoporosis. The Bone Health and Osteoporosis Foundation estimates that approximately 10 million Americans have osteoporosis, with another 44 million carrying low bone density. The same source attributes around 2 million fragility fractures annually to osteoporosis.
The ICD-10-CM code range for osteoporosis is M80 through M81. M81 is the ICD-10 code family for osteoporosis without current pathological fracture. M80 is the ICD-10 code family for osteoporosis with current pathological fracture. The M80 vs. M81 binary is the first question a coder must answer on every claim.
This guide covers the M80 and M81 catalogs, the 7th-character encounter system that drives M80 coding, the Z87.310 history code, and the separate osteopenia family (M85.8x). It also explains the CPT and J-code pairings for DXA imaging and osteoporosis drugs, the denial patterns, and the HCC and HEDIS implications. The FY2026 ICD-10-CM update took effect on October 1, 2025.
What Are the ICD-10 Codes for Osteoporosis?
The ICD-10-CM code range for osteoporosis is M80 through M81, with related codes in Z87.310 (history) and M85.8x (osteopenia). The codes sit inside Chapter 13 of ICD-10-CM under the M80–M85 block on disorders of bone density and structure.
What Is the M80–M81 Code Range in ICD-10-CM?
The M80 to M81 code range covers osteoporosis as a chronic bone disease. M80 captures osteoporosis with a current pathological fracture. M81 captures osteoporosis without a current pathological fracture. The full range sits inside Chapter 13 of ICD-10-CM.
What Is the Difference Between M80 and M81?
M80 is used when the patient has an active pathological fracture caused by osteoporosis. M81 is used when osteoporosis is documented, but no current pathological fracture is present. The two families never coexist as primary codes on the same claim.
How Does Z87.310 Fit Into This Family?
Z87.310 is the ICD-10 code for personal history of (healed) osteoporosis fracture. Z87.310 applies when the pathological fracture is fully healed, but documentation must capture the historical fracture for risk stratification, screening, and HCC purposes. Z87.310 pairs with an active M81 code.
Is Osteopenia Coded the Same as Osteoporosis?
Osteopenia is coded under M85.8x, not M81, in ICD-10-CM. The two are separate clinical states. Osteopenia is defined by a DXA T-score between -1.0 and -2.5. Osteoporosis requires a T-score of -2.5 or lower or a documented fragility fracture.
Why Does the M80 vs. M81 Distinction Drive Reimbursement?
The M80 vs. M81 distinction drives reimbursement because M80 codes carry higher relative weights, support fracture-management procedural claims, and capture HCC 39 in the CMS-HCC V28 model. M81 supports chronic-condition management claims and annual HCC recapture, but does not support acute fracture procedural claims.
How Do You Decide Between M80, M81, Z87.310, and S-Codes?
The decision between M80, M81, Z87.310, and S-codes follows a four-path logic based on fracture status and mechanism. The four paths cover active pathological fracture, no current fracture, healed pathological fracture, and acute traumatic fracture.
What Is the Four-Path Decision Logic for Osteoporosis Coding?
The four-path logic works as follows.
- Active Pathological Fracture Present: Use M80 as primary. The 7th character marks the encounter type.
- No Current Fracture, Osteoporosis Documented: Use M81 as primary.
- Healed Pathological Fracture, No Current Fracture: Use M81 with Z87.310 as secondary.
- Acute Traumatic Fracture with Osteoporosis Documented: Use the S-code injury family for the fracture, then M81 as secondary for the underlying osteoporosis.
When Is M81 the Correct Primary Diagnosis?
M81 is the correct primary diagnosis in three scenarios: chronic management visits, initial diagnosis without fracture, and follow-up after a healed fracture.
Annual Follow-Up and Chronic-Disease Management
Annual follow-up and chronic-disease management visits use M81 as primary when no current pathological fracture exists. The note records DXA history, treatment plan, and any prior fracture history through Z87.310 as a secondary code.
Initial Diagnosis Without Current Fracture
Initial diagnosis encounters use M81 when a DXA scan or clinical workup confirms osteoporosis, but the patient has no current pathological fracture. M81.0 captures age-related osteoporosis. M81.6 captures localized osteoporosis. M81.8 captures other osteoporosis types.
After a Healed Pathological Fracture (Paired With Z87.310)
After a healed pathological fracture, M81 pairs with Z87.310. The healed status removes the patient from M80 coding. The Z87.310 pairing preserves the fracture history for risk stratification and HCC recapture.
When Is M80 the Correct Primary Diagnosis?
M80 is the correct primary diagnosis whenever a current pathological fracture from osteoporosis is documented. M80 codes carry a 7th character that marks the encounter type within the healing timeline.
Active Pathological Fracture From Osteoporosis
Active pathological fractures from osteoporosis use M80 with 7th character A (initial encounter). The 7th character A applies during the active treatment phase: ER visits, surgical fixation, and the first weeks of management.
Subsequent Care for a Pathological Fracture
Subsequent care for a pathological fracture uses M80 with 7th character D. The 7th character D applies during routine healing, follow-up visits, and rehabilitation after active treatment ends.
Sequela of a Healed Pathological Fracture
Sequela of a healed pathological fracture uses M80 with 7th character S. The 7th character S applies when a late effect of the original fracture is the reason for the encounter, such as chronic deformity or residual disability.
How Do You Code Pathological vs. Traumatic Fractures in Osteoporotic Patients?
Pathological and traumatic fracture coding diverge based on the documented mechanism. Pathological fractures use M80. Traumatic fractures use S-codes. The provider’s documentation of the mechanism is the deciding factor.
When the Mechanism Supports Pathological Coding (M80)
The mechanism supports pathological coding (M80) when the fracture occurs from a low-energy event such as a ground-level fall, normal lifting, or no identifiable trauma. Vertebral compression fractures without trauma routinely code under M80.08x.
When Significant Trauma Supports S-Code Injury Coding
Significant trauma supports S-code injury coding when the fracture occurs from a high-energy event, such as a motor vehicle collision or fall from height. The injury S-code takes primary, with M81 as secondary to capture the underlying osteoporosis.
What If Both Pathological and Traumatic Elements Are Documented?
Mixed documentation requires a provider query. The coder cannot infer the mechanism. The query asks the provider to clarify whether the trauma was significant enough to cause the fracture in a non-osteoporotic patient.
What Are the M81 Codes? (Osteoporosis Without Current Pathological Fracture)
The M81 family captures osteoporosis without a current pathological fracture. The table below lists every billable M81 code.
What Are All the Codes in the M81 Family?
The M81 family contains three subgroups by clinical type, as listed below.
| Code | Description |
|---|---|
| M81.0 | Age-related osteoporosis without current pathological fracture |
| M81.6 | Localized osteoporosis (Lequesne) |
| M81.8 | Other osteoporosis without current pathological fracture |
When Should You Use M81.0 (Age-Related Osteoporosis)?
M81.0 is the ICD-10 code for age-related osteoporosis without a current pathological fracture. M81.0 covers the most common osteoporosis presentations, including postmenopausal and senile osteoporosis. The note must document the diagnosis and confirm no current pathological fracture.
How Does M81.0 Map to Postmenopausal and Senile Osteoporosis?
Postmenopausal osteoporosis icd 10 routes to M81.0. Senile osteoporosis icd 10 also routes to M81.0. ICD-10-CM consolidates both clinical subtypes under the age-related primary code. The provider’s note describes the clinical context; coders assign M81.0 in both cases.
When Is M81.6 (Localized Osteoporosis) the Correct Code?
M81.6 applies when osteoporosis is documented in a specific anatomic region rather than systemically. M81.6 is uncommon in routine practice but appears in cases of regional disuse osteoporosis or transient regional osteoporosis.
How Do You Code Drug-Induced and Other Osteoporosis Under M81.8?
Drug-induced osteoporosis ICD 10 routes to M81.8 (other osteoporosis without current pathological fracture). M81.8 also covers idiopathic osteoporosis and osteoporosis from other causes that do not match M81.0 or M81.6.
The “Code First” Rule for T36–T50 Adverse Effect Codes
Drug-induced osteoporosis requires “code first” sequencing. The T36–T50 adverse effect code (with 5th character 5) sequences first, followed by M81.8. The T-code identifies the responsible drug and its adverse effect status.
Glucocorticoid-Induced Osteoporosis Documentation
Glucocorticoid-induced osteoporosis is the most common drug-induced form. The note must document the glucocorticoid (such as prednisone), dose, duration, and the clinical confirmation of osteoporosis. The claim sequences T38.0X5A (or appropriate T-code) before M81.8.
What Are the M80 Codes? (Osteoporosis With Current Pathological Fracture)
The M80 family captures osteoporosis with a current pathological fracture. M80 codes are the most code-dense in the osteoporosis family because they combine anatomic site, laterality where applicable, and a 7th-character encounter type. Providers can consult a detailed ICD 10 codes guide to navigate these intricate multi-axis coding demands seamlessly.
What Are All the Codes in the M80 Family?
The M80 family splits into two clinical groups (.0 age-related, .8 other) and seven anatomic sites, as summarized below.
| Code Group | Description |
|---|---|
| M80.00xx | Age-related osteoporosis with fracture, unspecified site |
| M80.0xxx | Age-related osteoporosis with fracture at specified site (vertebra, shoulder, humerus, forearm, hand, femur, lower leg, ankle, foot) |
| M80.80xx | Other osteoporosis with fracture, unspecified site |
| M80.8xxx | Other osteoporosis with fracture at specified site |
How Are M80 Codes Built by Anatomic Site and Laterality?
M80 codes use the 5th character for anatomic site and the 6th character for laterality (1 right, 2 left, 9 unspecified) where applicable. The 7th character marks the encounter type. This system designates the exact ICD 10 codes for Orthopedic billing needed to reflect the severity of the fracture.
Vertebra (M80.08xx, M80.88xx)
M80.08x covers age-related osteoporosis with vertebral fracture. M80.88x covers other osteoporosis with vertebral fracture. Vertebra does not carry laterality. Vertebral compression fractures are the most common pathological fracture pattern in osteoporosis.
Shoulder and Humerus (M80.02xx, M80.82xx)
M80.02x covers age-related osteoporosis with a shoulder or humerus fracture. M80.82x covers other osteoporosis with the same site. Laterality is captured in the 6th character.
Forearm (M80.03xx, M80.83xx)
M80.03x covers age-related osteoporosis with forearm fracture. M80.83x covers other osteoporosis. Forearm fractures include distal radius (Colles) and ulnar pathological fractures.
Hand (M80.04xx, M80.84xx)
M80.04x covers age-related osteoporosis with a hand fracture. M80.84x covers other osteoporosis. Laterality is captured in the 6th character.
Femur (M80.05xx, M80.85xx)
M80.05x covers age-related osteoporosis with femur fracture. M80.85x covers other osteoporosis. Femoral neck and intertrochanteric fractures dominate this category and carry the highest mortality among osteoporotic fractures.
Lower Leg (M80.06xx, M80.86xx)
M80.06x covers age-related osteoporosis with lower leg fracture. M80.86x covers other osteoporosis. Lower leg includes tibia and fibula pathological fractures.
Ankle and Foot (M80.07xx, M80.87xx)
M80.07x covers age-related osteoporosis with ankle or foot fracture. M80.87x covers other osteoporosis. Laterality is captured in the 6th character.
When Do You Use M80.0 vs. M80.8?
M80.0 applies to age-related osteoporosis with current fracture. M80.8 applies to other osteoporosis (including drug-induced and idiopathic) with current fracture. The clinical context recorded in the note determines the choice.
How Does the 7th-Character Encounter System Work in M80 Codes?
The 7th-character encounter system in M80 codes uses three letters: A, D, and S. The system mirrors injury coding for traumatic fractures but applies to pathological fractures from osteoporosis.
A: Initial Encounter (Active Treatment)
The 7th character A applies during the active treatment phase of the fracture. Active treatment includes ER care, surgical fixation, and the first weeks of management. M80.00XA is the most-searched M80 code because the unspecified-site, age-related code with initial encounter is a frequent default.
D: Subsequent Encounter (Routine Healing)
The 7th character D applies during routine healing. D covers follow-up visits, cast changes, rehabilitation, and routine post-operative care that does not involve active treatment of the original fracture.
S: Sequela (Late Effect)
The 7th character S applies when a late effect of the original fracture is the reason for the encounter. Examples include chronic kyphosis after vertebral compression fracture and chronic disability from a healed femoral fracture.
When Is the “X” Placeholder Character Required?
The “X” placeholder character holds the 6th position when the code structure has fewer characters than the 7th-character slot requires. The placeholder rule is mandatory in M80 codes that need fewer than six meaningful characters before the encounter character.
How Is Osteopenia Coded vs. Osteoporosis?
Osteopenia is coded under M85.8x, not M81, in ICD-10-CM. The two conditions are clinically and code-wise distinct. Coders who treat osteopenia as a milder M81 cause downstream HCC capture errors and DXA medical-necessity denials.
What Are the ICD-10 Codes for Osteopenia?
The osteopenia icd 10 codes sit under M85.8 (other specified disorders of bone density and structure). The billable codes appear below.
| Code | Description |
|---|---|
| M85.80 | Other specified disorders, unspecified site |
| M85.81x | Other specified disorders, shoulder (.811 right, .812 left, .819 unspecified) |
| M85.85x | Other specified disorders, thigh (with laterality) |
| M85.89 | Other specified disorders, multiple sites |
How Is Osteopenia Different From Osteoporosis Clinically and in Coding?
Osteopenia is low bone density that does not meet the diagnostic threshold for osteoporosis. The DXA T-score for osteopenia is between -1.0 and -2.5. The T-score for osteoporosis is -2.5 or lower, or a documented fragility fracture confirms the diagnosis.
How Do T-Score and Z-Score Documentation Drive Code Choice?
T-score documentation drives the code choice between osteopenia (M85.8x) and osteoporosis (M81 or M80). Z-score documentation supports the diagnosis in younger or premenopausal patients. The provider’s note must record the actual numeric T-score and the anatomic site of measurement.
Why Is Osteopenia Often Miscoded as M81?
Osteopenia is often miscoded as M81 because clinicians and coders treat it as a milder form of osteoporosis. M81 requires a T-score of -2.5 or lower or a documented fragility fracture. Coding osteopenia as M81 inflates HCC capture and triggers audit risk.
What Documentation Supports Osteoporosis ICD-10 Claims?
Documentation supports osteoporosis ICD-10 claims when the provider’s note captures diagnosis confirmation, T-score, fracture status, fracture mechanism, and treatment plan. ICD-10-CM Official Guidelines require complete documentation for code assignment.
What Clinical Elements Must the Provider’s Note Contain?
The provider’s note must capture five clinical elements that drive code selection.
- Diagnosis statement (osteoporosis, osteopenia, or related)
- T-score and Z-score with anatomic site
- Current fracture status (present or absent)
- Fracture mechanism when present (pathological or traumatic)
- Treatment plan or medication status
How Should T-Score, Z-Score, and FRAX Score Be Documented?
T-score, Z-score, and FRAX score documentation captures the diagnostic basis for osteoporosis or osteopenia coding. The note records the numeric scores, the anatomic measurement sites, and the date of the DXA scan. FRAX scores support fracture risk stratification.
How Should the Fracture Mechanism Be Documented?
The fracture mechanism is documented as the energy level and circumstances of the fracture event. Low-energy mechanisms (ground-level fall, no trauma) support pathological coding (M80). High-energy mechanisms (motor vehicle collision, fall from height) support traumatic coding (S-codes).
How Do You Document Drug-Induced Osteoporosis for M81.8 Coding?
Drug-induced osteoporosis documentation for M81.8 coding requires three elements. The responsible drug must be named in the note. The duration and dose must be recorded. The causal link between the drug and the bone-density change must be clinically established.
What Are the MEAT Criteria for Chronic-Condition Recapture?
MEAT criteria are Monitor, Evaluate, Assess, and Treat. Each year’s HCC recapture for osteoporosis requires documentation of at least one MEAT element. Monitoring includes DXA history. Evaluating includes T-score review. Assessing includes risk stratification. Treating includes medication or supplement management.
Which CPT, HCPCS, and J-Codes Pair With Osteoporosis ICD-10 Codes?
Osteoporosis ICD-10 codes pair with CPT codes for DXA imaging, J-codes for pharmacy buy-and-bill, and E&M codes for management visits. Correct pairing supports medical necessity for screening, treatment, and follow-up claims.
Which DXA Scan and Imaging Codes Pair With M80, M81, and M85.8x?
DXA imaging codes are the highest-volume CPT codes paired with osteoporosis diagnoses. The table below summarizes the codes and their indications.
| Code | Description | Common ICD-10 Pairing |
|---|---|---|
| 77080 | Axial DEXA (hip and spine) | M81.0, M85.8x, Z13.820 |
| 77081 | Peripheral DEXA | M81.0, M85.8x |
| 77085 | Axial DEXA with vertebral fracture assessment | M81.0, M80.08xx |
| 77086 | Vertebral fracture assessment only | M81.0, M80.08xx |
| Z13.820 | Encounter for screening for osteoporosis | Paired with screening DXA when no diagnosis exists |
Axial DEXA (CPT 77080)
CPT 77080 covers axial DEXA of the hip and spine. CPT 77080 is the most common osteoporosis screening icd 10 procedural code. Medicare covers 77080 every two years for qualifying patients.
Peripheral DEXA (CPT 77081)
CPT 77081 covers peripheral DEXA of the forearm or heel. Peripheral DEXA is used when axial DEXA is not feasible or as a supplemental measurement.
Vertebral Fracture Assessment (CPT 77085, 77086)
CPT 77085 combines axial DEXA with vertebral fracture assessment. CPT 77086 covers vertebral fracture assessment alone. Both pair with M81.0 for chronic management and with M80.08xx when a vertebral pathological fracture is current.
Screening DEXA Under Medicare
Screening DEXA under Medicare uses Z13.820 as the primary diagnosis when no osteoporosis is documented yet. Medicare requires the patient to meet eligibility criteria, including age, postmenopausal status, or risk factor presence.
Which Pharmacy J-Codes Pair With Osteoporosis Diagnoses?
Pharmacy J-codes for osteoporosis drugs require pairing with an M80 or M81 diagnosis. Most payers require prior authorization before drug administration.
J0897: Denosumab (Prolia)
J0897 covers denosumab (Prolia) injection. The product is administered every six months. Pair J0897 with M81.0 for postmenopausal patients or with the appropriate M80 code when fracture is current.
J3489: Zoledronic Acid (Reclast)
J3489 covers zoledronic acid (Reclast) infusion. The product is administered annually. Pair J3489 with the active M81 or M80 code based on fracture status.
J3110: Teriparatide (Forteo)
J3110 covers teriparatide (Forteo) injection. The product is administered daily by self-injection. Payers commonly require failure of bisphosphonates before approval.
J3111: Romosozumab (Evenity)
J3111 covers romosozumab (Evenity) injection. The product is administered monthly for up to 12 doses. Pair J3111 with the active osteoporosis code and document the high-fracture-risk indication.
Which E&M Codes Are Most Commonly Billed With Osteoporosis?
E&M codes 99202–99205 (new patient office), and 99211–99215 (established patient office) are most commonly billed with M81 for chronic management. Annual wellness visits (G0438, G0439) routinely include osteoporosis screening discussions paired with Z13.820.
How Do You Avoid CPT–ICD-10 Mismatches for Osteoporosis Claims?
Coders avoid CPT–ICD-10 mismatches by checking three points before submission. The fracture status matches the code family (M80 for current fracture, M81 for no current fracture). The screening code Z13.820 is used only when no osteoporosis diagnosis exists yet. The J-code prior authorization is in place before drug administration.
What Are the Most Common Osteoporosis Coding Denials, and How Do You Prevent Them?
Osteoporosis coding denials come from M80/M81 binary errors, wrong 7th characters, osteopenia miscoding, DXA medical-necessity gaps, and J-code authorization failures. Each pattern has a known prevention path.
Why Are M81 Claims Denied When a Current Pathological Fracture Is Present?
M81 claims are denied when a current pathological fracture is documented because the correct code family is M80. Payer edits flag the mismatch between the diagnosis code and procedural codes for fracture management. The fix is to switch to M80 with the correct 7th character.
Why Are M80 Claims Denied With the Wrong 7th Character?
M80 claims are denied with the wrong 7th character when the encounter type does not match the clinical status. An M80 claim with 7th character A for a routine follow-up visit is denied because A applies only to active treatment. Dedicated orthopedic medical billing services eliminate this error by automating encounter timeline checks prior to submission.
Why Are Traumatic Fractures Denied When Osteoporosis Should Have Made Them M80?
Traumatic fractures are denied when a low-energy mechanism documented in the chart should have routed the code to M80 rather than to an S-code. The fix is to query the provider on the mechanism and select M80 when the chart supports pathological coding. Elite billing companies for orthopedic practices handle this provider query loop seamlessly to protect the practice from downcoding.
Why Are Osteopenia Claims Denied When Coded as M81?
Osteopenia claims coded as M81 are denied because osteopenia does not meet the M81 diagnostic threshold. The T-score for osteopenia falls between -1.0 and -2.5, not at or below -2.5. The fix is to code osteopenia as M85.8x.
Why Are DXA Claims Denied for Medical Necessity?
DXA claims are denied for medical necessity when the diagnosis code does not support the procedure. Screening DXA paired with M81 (when no diagnosis exists) triggers denial. The fix is to use Z13.820 for screening encounters and reserve M81 for confirmed diagnoses.
Why Are J-Code Claims Denied for Prior Authorization?
J-code claims for Prolia (J0897), Reclast (J3489), Forteo (J3110), and Evenity (J3111) are denied when prior authorization is missing or the supporting diagnosis is incorrect. Most payers require documented T-score, fracture history, and prior treatment failure for high-cost agents.
What Are the Payer-Specific Rules for Osteoporosis Coding?
Payer rules for osteoporosis vary by program and procedure. The table below summarizes the most common requirements.
| Payer | Common Rule |
|---|---|
| Medicare | DXA covered every 2 years for qualifying patients; T-score and indication required for J-code claims |
| BCBS plans | Prior authorization for Prolia, Reclast, Forteo, Evenity; step therapy in many plans |
| UnitedHealthcare | Step therapy required before Evenity and Forteo in most policies |
| Aetna | T-score documentation required for all osteoporosis drug authorizations |
| Medicare Advantage | HCC 39 capture requires annual MEAT documentation for M80 or M81 codes |
How Does Osteoporosis Coding Affect HCC Risk Adjustment and HEDIS Quality Measures?
Osteoporosis coding affects HCC risk adjustment in the CMS-HCC V28 model and HEDIS quality measures in the NCQA OMW measure. Both tie directly to ICD-10 code selection and documentation completeness.
How Do M80 Codes Map to HCC 39 in the CMS-HCC V28 Model?
M80 codes map to HCC 39 (osteoporotic fracture) in the CMS-HCC V28 model. The HCC carries a risk score that supports Medicare Advantage capitation. Accurate M80 coding during the active fracture year captures the HCC; missing the M80 forfeits the risk-adjusted revenue.
How Are M81 Codes Captured for Annual HCC Recapture?
M81 codes support annual HCC recapture for chronic osteoporosis when documented with MEAT criteria. Each year’s chart must show Monitor, Evaluate, Assess, or Treat documentation for the osteoporosis diagnosis. Missing MEAT in a calendar year drops the HCC from the risk score.
How Does NCQA HEDIS OMW Tie to Coding?
NCQA HEDIS OMW (Osteoporosis Management in Women Who Had a Fracture) tracks whether women aged 67–85 with a recent fracture receive DXA or osteoporosis medication within six months. The measure pulls from claims data, so accurate fracture coding and DXA or J-code claims drive the quality score.
What Is the Dual-Purpose Documentation Strategy for Claims and Quality?
The dual-purpose documentation strategy captures clinical facts that satisfy both claim coding and quality measure logic. The note records diagnosis, T-score, fracture status, MEAT activity, and treatment plan in a single structured section. Coders pull the right code; quality teams pull the right denominator hit.
What Changed in the FY2026 ICD-10-CM Update for Osteoporosis?
The FY2026 ICD-10-CM update for osteoporosis took effect October 1, 2025. The M80, M81, and M85.8x families carried no structural changes. NCHS and CMS publish the addenda each summer before the October 1 effective date.
Were Any M80, M81, or M85.8x Codes Added, Revised, or Deleted Effective October 1, 2025?
The FY2026 update preserved the M80, M81, M85.8x, and Z87.310 codes used for osteoporosis coding. Practices verify against the CMS-published FY2026 code set and the ICD-10-CM Official Guidelines for Coding and Reporting.
Do FY2026 Changes Affect HCC V28 Capture for Osteoporosis?
FY2026 changes do not affect HCC V28 capture for osteoporosis. The V28 model published by CMS continues to recognize M80 codes for HCC 39 and to require MEAT-documented M81 codes for annual recapture.
What Audit Exposures Does FY2026 Create for M81 and Osteopenia Coding?
Audit exposure on M81, paired with current fracture documentation and on osteopenia miscoded as M81, continues at the same pattern. Payers and CMS contractors flag practices that exceed peer benchmarks for these patterns.
Frequently Asked Questions About Osteoporosis ICD-10 Coding
The answers below cover the highest-volume specific-code searches and the most-cited osteoporosis coding questions from billers, coders, and HCC abstractors.
What Is the ICD-10 Code for Osteoporosis?
The ICD-10 code range for osteoporosis is M80 through M81. M81.0 covers age-related osteoporosis without current fracture. M80 covers osteoporosis with a current pathological fracture. The exact code depends on fracture status, anatomic site, and encounter type.
What Is the ICD-10 Code for Postmenopausal Osteoporosis?
Postmenopausal osteoporosis ICD 10 routes to M81.0 (age-related osteoporosis without current pathological fracture). ICD-10-CM does not separate postmenopausal osteoporosis from senile osteoporosis at the code level. Both clinical subtypes consolidate under M81.0.
What Is the ICD-10 Code for Senile Osteoporosis?
Senile osteoporosis ICD 10 routes to M81.0. The same code covers postmenopausal osteoporosis. The provider’s note describes the clinical context for medical record purposes.
What Is the ICD-10 Code for Osteopenia?
The osteopenia ICD 10 code is M85.80 for unspecified site. M85.81x covers the shoulder with laterality. M85.85x covers the thigh with laterality. M85.89 covers multiple sites. Osteopenia is not coded under M81.
What Is the Difference Between M80 and M81?
M80 covers osteoporosis with a current pathological fracture. M81 covers osteoporosis without a current pathological fracture. M80 carries a 7th-character encounter type (A, D, or S). M81 does not require a 7th character.
What Is M81.0?
M81.0 is the ICD-10 code for age-related osteoporosis without current pathological fracture. M81.0 is the most common osteoporosis code in US claims data and covers postmenopausal and senile osteoporosis presentations.
What Is M80.00XA?
M80.00XA is the ICD-10 code for age-related osteoporosis with current pathological fracture, unspecified site, initial encounter. The “X” is a placeholder character; “A” is the 7th-character encounter marker for active treatment.
What Is the ICD-10 Code for History of Osteoporosis With Fracture?
Z87.310 is the ICD-10 code for personal history of (healed) osteoporosis fracture. Z87.310 pairs with an active M81 code to capture historical fracture status when the fracture is fully healed.
Can M81 and a Fracture S-Code Be on the Same Claim?
M81 and an S-code can be on the same claim when the fracture is traumatic rather than pathological. The S-code is primary for the acute injury. M81 is secondary to capture the underlying osteoporosis. The provider’s documented mechanism drives the decision.
Is Osteoporosis a Chronic Condition for HCC Recapture?
Osteoporosis is a chronic condition that requires annual HCC recapture under the CMS-HCC V28 model. Each calendar year’s documentation must include MEAT activity (Monitor, Evaluate, Assess, or Treat) tied to the osteoporosis diagnosis to preserve the HCC capture.
