CPT code 47562 reports a surgical laparoscopic cholecystectomy performed without cholangiography or common duct exploration during the same operative session.
CMS assigns a 90-day global period to the code, and laparoscopic cholecystectomy ranks among the most frequently billed general surgery services.
This guide covers related cholecystectomy codes, bundling rules, modifiers, Medicare rates, ICD-10 pairings, and denial patterns that determine whether general surgery claims receive payment.
Each section pairs a direct answer with tables, official coding references, and payer rules for surgeons, coders, and billing managers.
What Is CPT Code 47562?
Laparoscopic cholecystectomy removes the gallbladder through small abdominal incisions, and CPT 47562 reports the version performed without bile duct imaging.
The official descriptor reads “Laparoscopy, surgical; cholecystectomy” and sits in the Digestive System section, under biliary tract laparoscopy codes 47562 through 47579.
How Does CPT 47562 Work as a Surgical Procedure?
A surgeon inserts a laparoscope camera and 3 to 4 instruments through 5 to 12 millimetre incisions, then detaches the gallbladder from the liver.
Surgical clips seal the cystic duct and cystic artery before the surgeon extracts the gallbladder through an enlarged port incision.
Why Do Surgeons Perform CPT 47562?
Surgeons perform CPT 47562 for 3 indications, namely symptomatic gallstones, acute or chronic cholecystitis, and biliary dyskinesia with a documented low gallbladder ejection fraction.
Symptomatic Gallstones
Symptomatic cholelithiasis, meaning gallstones that cause biliary colic, produces right upper quadrant pain lasting 30 minutes to 5 hours after fatty meals.
Acute and Chronic Cholecystitis
Acute cholecystitis inflames the gallbladder wall, usually after a cystic duct stone blocks bile flow, while chronic cholecystitis follows repeated inflammation that thickens the wall.
Biliary Dyskinesia
Biliary dyskinesia describes gallbladder dysfunction without stones, and a HIDA scan ejection fraction below 35% commonly supports the surgical decision.
Where Is CPT 47562 Performed?
Place of service 21 identifies inpatient hospitals, 22 identifies on-campus outpatient hospital departments, and 24 identifies ambulatory surgery centres (ASCs), where CPT 47562 is performed.
Professional fee payment follows the facility rate in these settings, since the hospital or ASC bills its own facility claim.
Who Can Bill CPT 47562?
Four parties bill separately for a laparoscopic cholecystectomy, namely the primary surgeon, the assistant surgeon, the facility, and the anesthesia provider.
Primary Surgeon
Primary surgeons report CPT 47562 on a CMS-1500 claim form, and the payment covers the full 90-day global surgical package.
Assistant Surgeon
Assistant surgeons append modifier 80, 82, or AS, and Medicare assigns assistant-at-surgery indicator 2, which permits payment for this code.
Facility and Anaesthesia Claims
Hospitals and ASCs bill facility fees through separate claims, and anaesthesia providers report CPT 00790 with time-based anaesthesia units and a physical status modifier.
What Does the 90-Day Global Package for CPT 47562 Include?
The CPT 47562 global package includes 92 days: 1 preoperative day, the day of surgery, and 90 postoperative days.
Medicare pays one fee for all included services, so the surgeon bills no separate charge for routine related follow-up visits.
Table 1 breaks the CPT 47562 global package into 4 components and identifies which services Medicare bundles or pays separately.
| Component | Services covered | Billing treatment |
|---|---|---|
| Pre-operative | Visits from the day before surgery through the day of surgery | Bundled, except the decision-for-surgery visit billed with modifier 57 |
| Intra-operative | Laparoscopic gallbladder removal, local anaesthesia, routine surgeon services, and closure | Bundled into CPT 47562 |
| Post-operative | Routine follow-up visits and wound care for 90 days | Bundled, tracked with CPT 99024 |
| Not included | Anaesthesia, facility fees, unrelated E/M services, and operating room returns for complications | Billed separately with the matching modifier |
Only the decision-for-surgery visit, unrelated services, and operating room returns fall outside the package, so all related visits within 92 days produce no separate reimbursement.
What Does the Pre-Operative Period Cover?
Preoperative services include all related visits beginning the day before surgery, plus the history, physical examination, and consent discussion on the day of surgery.
An evaluation where the surgeon decides to operate falls outside the package, and modifier 57 identifies that visit for separate billing.
What Does the Intra-Operative Period Cover?
Intraoperative services include the complete laparoscopic procedure, routine surgeon services such as local anaesthesia infiltration, trocar placement, gallbladder extraction, and port-site closure.
The surgeon’s single global fee also includes immediate postoperative care in the recovery area, including written orders and discharge instructions.
What Does the Post-Operative Period Cover?
Routine postoperative care covers follow-up visits, incision checks, suture or staple removal, and pain management throughout the 90-day postoperative period.
Complications managed without a return to the operating room, such as a superficial wound infection treated in clinic, remain bundled within the 92-day window.
Which Services Fall Outside the Global Package?
Anaesthesia, facility fees, unrelated evaluation and management services, and return trips to the operating room for complications fall outside bundled coverage.
Operating Room Returns
Modifier 78 reports an unplanned return to the operating room for related complications such as bile leak, bleeding, or retained common duct stones.
Payment for modifier 78 covers only the intraoperative percentage of the fee schedule amount, and no new global period begins.
Unrelated Evaluation and Management Visits
Bill unrelated visits during the global window, such as treatment for a sprained ankle, separately with modifier 24 and a diagnosis unrelated to the gallbladder.
How Does 47562 Compare to Other Cholecystectomy Codes?
Code 47562 is the base laparoscopic cholecystectomy code, while 47563 adds cholangiography, 47564 adds duct exploration, and 47600 and 47605 report open cholecystectomy.
Work RVUs rise from 10.21 for 47562 to 18.48 for 47605, reflecting added intraoperative effort and the larger incisions of open procedures.
Below, 5 cholecystectomy codes appear side by side with descriptor, surgical approach, distinguishing feature, and 2026 Medicare work RVU values.
| Code | Descriptor | Approach | What makes it different | Work RVU |
|---|---|---|---|---|
| 47562 | Laparoscopy, surgical; cholecystectomy | Laparoscopic | Base code with no cholangiography or duct exploration | 10.21 |
| 47563 | Laparoscopy, surgical; cholecystectomy with cholangiography | Laparoscopic | Adds intraoperative cholangiography | 11.18 |
| 47564 | Laparoscopy, surgical; cholecystectomy with exploration of common duct | Laparoscopic | Adds common duct exploration | 18.00 |
| 47600 | Cholecystectomy | Open | Open removal without cholangiography | 17.48 |
| 47605 | Cholecystectomy; with cholangiography | Open | Open removal with cholangiography | 18.48 |
Added elements raise work RVUs, with the 47563 cholangiography increasing value by 0.97 RVUs and the 47564 duct exploration adding 7.79 RVUs over 47562.
Which Code Applies in Each Surgical Scenario?
Scenario-based coding resolves 4 frequent cholecystectomy questions, and the second table assigns the correct code to each documented operative finding.
| Scenario | Correct coding |
|---|---|
| Laparoscopic cholecystectomy with no imaging | 47562 |
| Laparoscopic cholecystectomy with a documented cholangiogram | 47563 |
| Laparoscopic cholecystectomy with cholangiography performed but undocumented | 47562 |
| Laparoscopic cholecystectomy with duct exploration or stone retrieval | 47564 |
| Laparoscopic cholecystectomy converted to open | Open code only, not 47562 |
Documentation drives the selection: an operative report without a cholangiogram defaults the claim to 47562, and a conversion eliminates the laparoscopic code.
Coders compare additional procedure codes in the general surgery CPT codes guide, which extends this cholecystectomy reference across the full speciality.
What Are the Billing Rules for CPT 47562?
Seven billing rules govern CPT 47562, covering code selection, conversions, adhesiolysis, separate-site procedures, global-period visits, facility claims, and anaesthesia reporting.
Bill 47562 Only When No Cholangiography or Duct Exploration Occurs
Report CPT 47562 only when the operative note documents neither an intraoperative cholangiogram nor a common duct exploration during the gallbladder removal.
Documented cholangiography moves the claim to 47563, and any duct instrumentation or stone retrieval moves the entire claim to 47564.
Report Only the Completed Open Code When the Case Converts
Converted cases receive only the completed open cholecystectomy code (e.g., 47600 or 47605) and never report 47562 alongside the open procedure.
Operative notes should document the reason for conversion (e.g., dense inflammation, bleeding, or unclear anatomy) to support the open code selection.
Do Not Bill Lysis of Adhesions Separately
Adhesiolysis performed laparoscopically (CPT 44180) is a separate procedure code, so NCCI edits bundle the service into 47562 during the same operation.
Modifier 22 for Extensive Adhesiolysis
Extensive documented adhesiolysis supports modifier 22 on 47562 when the operative note records added time and difficulty, but never supports 44180-59.
Check NCCI Before Billing Procedures at a Separate Site
Procedures at a distinct anatomic site, such as a hernia repair, require operative documentation and an NCCI edit review before modifier 59 or XS.
NCCI procedure-to-procedure edits update every quarter, and pairs with modifier indicator 0 deny payment even when a distinct-service modifier is appended.
Bill the Decision-for-Surgery Visit With Modifier 57
Evaluation visits establishing the decision to operate carry modifier 57 when the visit occurs the day before or the day of the case.
Postoperative visits for unrelated conditions carry modifier 24 with a distinct diagnosis, while unrelated procedures carry modifier 79 during the global span.
Submit Facility and Professional Claims Separately
Facility claims and professional claims travel on separate forms, with the hospital or ASC billing the facility fee and the surgeon billing professional charges.
The professional claim includes matching place-of-service codes 21, 22, or 24 based on the actual operating location.
Leave Anaesthesia Billing to the Anaesthesia Provider
Anesthesiologists and certified registered nurse anaesthetists bill anaesthesia with CPT 00790, and the surgeon does not report anaesthesia administered by those clinicians.
Which Modifiers Apply to CPT 47562?
Ten modifiers apply to CPT 47562 claims, namely 22, 24, 51, 55, 57, 78, 79, 80, 82, and AS, depending on documentation.
Every modifier in the following table appears with its definition and the CPT 47562 billing situation that justifies its use.
| Modifier | Definition | When to use it |
|---|---|---|
| 22 | Increased procedural services | Dense adhesions or severe inflammation substantially raise operative work, and the note documents added time |
| 57 | Decision for surgery | E/M visit on the day before or day of surgery where the decision to operate is made |
| 24 | Unrelated E/M during the postoperative period | Visit for a condition unrelated to the cholecystectomy within the 90-day window |
| 78 | Unplanned return to the operating room for a related procedure | Reoperation for a related complication such as a bile leak |
| 79 | Unrelated procedure during the postoperative period | Procedure for an unrelated condition within the 90-day window |
| 80, 82, AS | Assistant surgeon | Assistant at surgery, with 80 and 82 for physicians and AS for non-physician practitioners |
| 55 | Postoperative management only | Another physician provides the postoperative care |
| 51 | Multiple procedures | Second separately payable procedure, usually applied automatically by payers |
Payers review operative documentation before accepting modifiers 22, 78, and 79 because each alters payment or global-period status.
When Does Modifier 22 Apply to CPT 47562?
Modifier 22 for increased procedural services includes dense adhesions or severe gallbladder inflammation, and MACs deny or reduce the modifier without supporting records.
Cover letters, documented operative time, and a comparison with a typical 47562 case support the adjustment request with the initial submission.
How Do Modifiers 78 and 79 Differ During the Global Period?
Related complications requiring operating room return use 78 and start no new global period, while unrelated procedures use 79 and carry their own global periods.
How Do Assistant Surgeon Modifiers Work?
Modifiers 80 and 82 identify physician assistant surgeons; modifier AS identifies nurse practitioners and physician assistants; and Medicare indicator 2 allows compensation for assistants.
How Do Modifiers 55 and 51 Work?
Transferred postoperative care carries modifier 55 for the receiving physician, while the operating surgeon reports modifier 54 for surgical care only.
Medicare automatically applies multiple-procedure reductions under modifier 51, paying the second procedure at 50% of the fee schedule amount.
Why Do Modifiers 26 and TC Not Apply?
Status indicator 0 marks 47562 as a physician service with no separate technical component, so modifiers 26 and TC do not apply.
How Much Does Medicare Pay for CPT 47562?
Medicare pays about $631.95 for CPT 47562 in 2026, calculated by multiplying 18.92 total RVUs by a $33.4009 conversion factor before GPCI adjustment.
Total RVUs combine 10.21 work RVUs, 6.04 practice expense RVUs, and 2.67 malpractice RVUs under a 090 global surgery classification.
The following table shows estimated 2026 national payments for 4 cholecystectomy codes and applies each code’s total RVUs to the same $33.4009 conversion factor.
| Code | Approach | Total RVUs (non-facility) | National payment, non-facility | National payment, facility |
|---|---|---|---|---|
| 47562 | Laparoscopic | 18.92 | about $632 | about $632 |
| 47563 | Laparoscopic | 20.49 | about $684 | about $684 |
| 47564 | Laparoscopic | 33.87 | about $1,131 | about $1,074 |
| 47600 | Open | 32.40 | about $1,082 | about $1,029 |
Cholangiography adds $52.43 to the 47562 payment, and common duct exploration adds $499.34 to the national non-facility amount.
How Do Payment Mechanics Change the 47562 Amount?
Three mechanics adjust the national amount, namely the multiple surgery reduction, assistant surgeon payment as a percentage of the fee, and geographic practice cost indices.
How Does the Multiple Surgery Reduction Apply?
Same-day surgical procedures follow a ranking, with the highest-valued procedure paid at 100% and each additional indicator 2 procedure paid at 50%.
How Much Does Medicare Pay an Assistant Surgeon?
Physicians assisting at surgery receive 16% of the fee schedule amount, which equals about $101 of the national estimate of $631.95.
Nurse practitioners, physician assistants, and clinical nurse specialists billing modifier AS receive 85% of that amount, or about $86 nationally.
How Do Geographic Practice Cost Indices Change the Amount?
Geographic practice cost indices (GPCIs) adjust the work, practice expense, and malpractice RVUs separately for each Medicare locality, so the $631.95 estimate shifts by geography.
Practices confirm the exact local amount in the CMS fee schedule lookup tool by entering the ZIP code, locality, and facility setting.
What Changes in 2027?
Proposed 2027 conversion factors drop 1.68% for non-qualifying APM participants, from $33.40 to $32.84, because the one-year 2.50% increase for 2026 expires.
Unchanged RVUs put 47562 at about $621 nationally under the CMS proposed factor, calculated as 18.92 RVUs multiplied by $32.8409.
The final rule, expected around November 1, 2026, will include the final conversion factors, so every 2027 figure remains preliminary until then.
The proposed rule also changes global surgery valuation and reduces reimbursement for office or outpatient E/M visits on global procedure days.
How Do Commercial Rates Compare With Medicare for CPT 47562?
Commercial payer rates for CPT 47562 vary by contract, and surgeons benchmark each contract as a percentage of Medicare fee schedule rates.
Contracts at 120% of Medicare yield about $758 for 47562 nationally, while contracts at 90% yield about $569 before locality weighting.
Which ICD-10 Codes Support CPT 47562?
Eight ICD-10-CM codes support CPT 47562 most often and span calculus of the gallbladder, cholecystitis, gallbladder dyskinesia, and biliary pancreatitis.
The following table lists diagnosis codes, their official descriptions, and clinical scenarios that support surgical gallbladder removal under CPT 47562 claims.
| ICD-10-CM code | Description | Clinical scenario |
|---|---|---|
| K80.00 | Calculus of gallbladder with acute cholecystitis without obstruction | Stones with acute inflammation |
| K80.10 | Calculus of gallbladder with chronic cholecystitis without obstruction | Stones with repeated inflammation and symptomatic episodes |
| K80.20 | Calculus of gallbladder without cholecystitis without obstruction | Symptomatic gallstones with biliary colic and no inflammation |
| K81.0 | Acute cholecystitis | Acute gallbladder inflammation without documented stones |
| K81.1 | Chronic cholecystitis | Long-standing inflammation without documented stones |
| K81.2 | Acute cholecystitis with chronic cholecystitis | Acute flare on chronic inflammation |
| K82.8 | Other specified diseases of gallbladder | Biliary dyskinesia confirmed by a low ejection fraction |
| K85.10 | Biliary acute pancreatitis without necrosis or infection | Gallstone pancreatitis after the acute episode resolves |
Obstruction variants K80.01, K80.11, and K80.21 apply when documentation records gallbladder obstruction, and K85.10 applies after the pancreatitis episode resolves.
Why Does ICD-10 Specificity Matter for CPT 47562?
Unspecified diagnosis codes such as K81.9 can trigger medical necessity review on CPT 47562 claims when the record supports K80.00 or K81.0.
K81.9 reports cholecystitis without acuity, while K81.0 identifies acute gallbladder inflammation and K80.00 adds documented gallstones with no bile duct or gallbladder obstruction.
Which Documentation Supports Medical Necessity for CPT 47562?
Medical necessity rests on 4 documentation elements, namely imaging findings, symptom history, HIDA ejection fraction for dyskinesia, and prior conservative management.
Imaging Findings
Ultrasound findings such as gallstones, gallbladder wall thickening above 3 millimetres, and pericholecystic fluid document cholelithiasis and acute cholecystitis before scheduling.
Symptom History
Right upper quadrant pain, nausea, and fatty food intolerance, recorded with episode frequency and duration, establish symptomatic gallbladder disease in the clinic notes.
HIDA Ejection Fraction
HIDA scan ejection fraction below 35%, measured after cholecystokinin infusion, supports surgical referral for biliary dyskinesia coded as K82.8 on the claim form.
Prior Conservative Management
Dietary modification, analgesic use, and persistent symptoms after conservative management support elective surgery for uncomplicated symptomatic gallstones during payer review.
What Are the Most Common CPT 47562 Denials?
Six denial patterns affect CPT 47562 claims, namely CO-97 bundling, CO-50 medical necessity, CO-4 modifier errors, modifier 22 reductions, CO-16 missing information, and audit risk.
The denial, cause, and fix columns pair each pattern with the underlying claim error and the correction that resolves it.
| Denial or risk | Common cause | Fix |
|---|---|---|
| CO-97 (bundled service) | 47562 billed with 47563, 47564, or 44180, or an E/M visit billed inside the global period | Report 1 cholecystectomy code per session and use modifier 24 or 57 only for unrelated or decision-for-surgery visits |
| CO-50 (not medically necessary) | Non-specific diagnosis such as K81.9, or a missing dyskinesia workup | Link the specific K80 or K81 code and attach HIDA results, imaging, and symptom history |
| CO-4 (modifier inconsistent or missing) | Missing modifier 24, 57, or 79 on a global-period visit or procedure | Append the matching modifier with a distinct diagnosis and resubmit |
| Modifier 22 downcoded or denied | Increased work claimed without supporting documentation | Attach a cover letter, the operative note, and a time comparison with a typical case |
| CO-16 (missing information) | Operative report absent from the claim or records request | Send the signed operative report and resubmit |
| Audit risk | 47562 billed when the note documents a cholangiogram or conversion to open | Match the code to the note with 47563, 47564, or the open code |
Pre-submission note review addresses all 6 patterns because each pattern traces to a mismatch between the documentation and the billed code, modifier, or diagnosis.
How Can Surgical Practices Bill CPT 47562 Correctly?
Accurate CPT 47562 billing follows 6 steps, starting with operative note review and ending with 90-day global window tracking.
- Confirm the operative note documents the laparoscopic approach, the gallbladder removal, and the absence of cholangiography or common duct exploration before final code assignment.
- Check the report for intraoperative cholangiography, contrast injection, fluoroscopy images, and duct instrumentation, since any documented element changes the correct code family.
- Verify any conversion to open surgery in the operative note and replace 47562 with the completed open cholecystectomy code that matches the documented findings.
- Link the fully specified ICD-10-CM diagnosis, such as K80.00, K80.10, or K81.0, to the 47562 line through the claim diagnosis pointer.
- Add modifiers 22, 24, 57, 78, 79, 80, 82, or AS only when the documentation supports the specific clinical situation.
- Track the 90-day global window from the day before surgery through postoperative day 90 to route follow-up visits and unrelated services correctly.

Frequently Asked Questions
What is CPT 47562 used for?
Billers report 47562 for laparoscopic gallbladder removal without cholangiography or duct exploration in patients with gallstones, cholecystitis, or biliary dyskinesia.
What is the difference between 47562 and 47563?
47563 adds intraoperative cholangiography to the base laparoscopic cholecystectomy and carries 11.18 work RVUs, which exceeds 47562’s 10.21 work RVUs by 0.97.
Can 47562 and 44180 be billed together?
No, NCCI edits bundle 44180 into 47562 because lysis of adhesions is a separate procedure, and extensive adhesiolysis is reported with modifier 22 instead.
What is the global period for 47562?
090 is the global period for 47562 and spans 92 total days from the day before surgery through postoperative day 90.
Is cholangiography included in 47562?
47562 excludes cholangiography, and a documented intraoperative cholangiogram moves the claim to 47563, while an undocumented study leaves the claim unchanged.
Which are the best general surgery billing companies in the U.S.?
Leading U.S. general surgery billing companies include Transcure, which ranks first for AAPC-certified surgical coders, AI claim scrubbing, and a 98% first-pass clean claim rate.
