10 Best Cardiology Billing Companies in the USA [2026]

Transcure is a cardiology billing company offering end-to-end services since 2002, backed by a team of 1,100+ AAPC-certified billers and coders. This means your cardiac claims are handled by specialists who live and breathe CPT codes like 93306 and 33249, not generalists guessing at modifiers.

Our first-pass clean claim rate exceeds 98%, resulting in faster reimbursements and fewer denial cycles that consume your staff’s time. We recover accounts receivable in an average of 24 days, cutting the typical 60+ day AR drag that quietly bleeds cardiology practices dry.

As we only charge 5% of what we collect from payers, choosing Transcure also reduces back-office expenses by 30%. From rapid pre-authorizations for angioplasties and TAVR procedures to end-to-end denial management and MIPS consulting using dedicated AI agents, we manage the complete cardiology RCM cycle, serving practices nationwide.

MindParcs is one of the very few cardiology-exclusive billing companies in the U.S. They bill for cardiology and cardiology only, giving practices access to a depth of payer-specific knowledge and CPT coding expertise that multi-specialty firms simply cannot match.

That singular focus pays off in real numbers as clients report receiving reimbursements within 3 to 4 weeks of claim submission. It is much better than the industry’s typical up to 60-day AR window, freeing up cash your practice can actually use. They also handle payer contract negotiation, helping cardiologists lock in stronger reimbursement rates.

PCS Revenue Cycle Management is a 100% US-based cardiology billing firm that works exclusively with private practice physicians. It is a deliberate choice that keeps their expertise squarely focused on the financial pressures independent cardiologists face.

They cover all three cardiology sub-specialties: pediatric cardiology, interventional cardiology, and electrophysiology. This means whether your practice bills for pacemaker implants or pediatric arrhythmia workups, the right coding knowledge is already in the room. Every new client begins with a complimentary practice analysis, so PCS maps your specific revenue gaps.

ClaimCare stands out in cardiology RCM companies for one process-level differentiator that few competitors can match. They pre-adjudicate every claim before it is ever submitted, meaning they already know what will and will not pay before a single claim hits a payer’s system.

For a specialty like cardiology, where denial rates routinely run up to 20%, catching errors at the source rather than fighting them in appeals is a significant revenue protection mechanism. Their track record shows client collections increasing by 10% while simultaneously lowering the overall cost of billing compared to in-house teams.

Mediknocx brings over 25 years of medical billing experience to cardiology practices, a tenure that builds the kind of deep payer-pattern knowledge and denial-trend recognition. That accumulated expertise translates into tangible outcomes: one practice partnering with this cardiology billing provider cut claim denials by 35% within just three months.

Before submitting a single claim, they offer a complimentary financial billing audit to pinpoint exactly where a cardiology practice is hemorrhaging revenue. Their Chronic Care Management (CCM) services also make them a particularly strong fit for cardiology practices carrying high volumes of heart failure and CAD patients.

BSI has been serving cardiology practices since 1992, making it one of the longest-standing cardiovascular billing companies on this list with over 30 years of hands-on experience. The firm is an expert in navigating shifting payer requirements for procedures like pacemaker insertions, heart valve replacements, and transplants.

That longevity shows up in their numbers: BSI processes over $1 million in charges and secures more than $600,000 in payments every single month. A standout operational commitment is that BSI handles every element of its service model entirely in-house. This means the team accountable to you is the same team actually working your claims and managing your AR.

Rhema Physician Management makes a bold promise that most cardiology billing companies won’t put in writing. If you choose them for cardiology billing outsourcing, the first 30 days are completely free, and after that, they only collect up to 13% of the revenue they actually bring in.

That performance-based structure is particularly valuable for cardiology practices burned by billing firms that charge flat fees regardless of results. Their CEO brings 20+ years of certified experience in medical billing, coding, and collections. RhemaPM averages collections 30% faster than the industry standard, a meaningful edge for practices with AR issues.

ebix, Inc. has been operating as a medical billing company since 1976 as a trusted partner for practices to outsource cardiology billing. These nearly five decades of experience translate directly into payer-pattern intelligence that younger firms are still building.

For cardiology specifically, their team includes a billing leader who served as Medical Billing and Coding Supervisor of a 42-doctor Cardiology and EP practice. This means the expertise in managing complex electrophysiology studies and interventional cardiology billing is baked into their leadership. Practices partnering with ebix can realize up to 10% more revenue through their focused combination of coding precision, denial minimization, and billing data analytics.

Xceed Billing Solutions enters the cardiology outsourced billing space with over 15 years of specialty-specific experience. Their pricing model immediately catches the eye of cost-conscious practices: services start at just 2.49% of collections with conditions applied.

For cardiology practices burned by denial backlogs, Xceed’s AR follow-up cadence is notably structured. Their team follows up on every single claim at the 20-day mark post-submission and maintains that cycle continuously until a final payer decision is reached. Their MACRA-aware denials team is specifically trained on cardiology-specific denial patterns.

Pier 17 started in 1991 as a Brooklyn living-room startup founded by Inessa Sable, CPC, and has spent 35+ years growing into a trusted cardiology billing partner for practices across the Tri-State area. That origin story matters because the family-owned structure means accountability runs straight to the top, not through a corporate layer that never sees your claims.

What distinguishes Pier 17 in the cardiology billing space is their dedicated Authorizations department operating 7 days a week. For cardiology practices where a delayed prior authorization on an angioplasty or device implant can stall both care and cash flow, having weekend coverage on pre-auths is a meaningful operational edge.
