10 Best Cardiology Billing Companies in the USA [2027]

Transcure is a cardiology billing company that runs full-cycle RCM inside a multi-specialty operation. Our 1,100+ AAPC-certified billers work interventional, electrophysiology, diagnostic, and device claims every day. That depth suits multi-location groups and practices that bill vascular or other specialties beside cardiology.

Cardiology claims break in two places, so our agents work both. CODIN reads the procedure note before coding, which catches a missing add-on vessel or an unsupported modifier 25. PRIA secures prior authorization for cath, PCI, device implants, and nuclear stress studies before the case reaches the schedule.

Claims go out within 48 hours of the encounter, so procedure revenue never sits in a coding queue. When a payer does deny, we recover 80% of those claims. Practices that move their cardiology billing to us typically see collections rise by 20% or more.

AnnexMed is a specialty-focused RCM company with dedicated expertise in cardiology medical billing. It helps cardiology practices manage accurate coding, claim submission, denial management, AR follow-up, and eligibility verification. Its cardiology-focused workflows are designed to improve claim accuracy and help practices recover missed revenue.

AnnexMed’s approach goes beyond basic billing by addressing different stages of the cardiology revenue cycle. By combining specialty-specific billing knowledge with structured RCM processes, it helps cardiology providers maintain cleaner claims, minimize denials, and improve overall revenue performance.

HealthQuist is a cardiology billing company option for group practices that want layered oversight on every claim. Separate quality control and compliance departments review work before it reaches payers. That structure suits cardiology groups worried about audit exposure on high-value procedure claims.

Beyond standard payer claims, the firm bills workers’ compensation, occupational medicine, and personal injury cases. Patient balances run as their own service line, apart from insurance follow-up. A consulting team also reviews payer contract wording and reimbursement gaps for practices that suspect money is being left uncollected.

VB Billing & Credentialing Services is a founder-led cardiology billing partner for practices in New York and South Florida. Valerie Bondarevsky built the firm after 25+ years managing medical practices, and she guides each account personally. Nothing is outsourced, so clients reach the in-house team directly.

The firm reaches past routine claims into no-fault and workers’ compensation billing, out-of-network navigation, and DME. Startup packages help new practices finish credentialing and payer contracting before the first claim goes out. Practice optimization consulting also covers front-office workflow for offices that are still finding their footing.

Billing Nerds is a compact billing provider for cardiology and rehab practices, started by clinicians unhappy with their own billing vendors. Its client base leans toward physical, occupational, and speech therapy. Clients praise its credentialing most, especially fast Medicare enrollment for newly added providers.

Each practice is assigned a dedicated account manager who reports on claim status and revenue trends. A separate documentation review service checks clinical notes before they turn into claims, which targets the error type behind most cardiology payment problems. Patient statements can also be handed off as a standalone service.

Resolve Medical Billing is a lean cardiology billing option run by CEO Crystal McIntyre, who has spent 20+ years in healthcare. It accepts new clients nationwide and puts communication first. Each practice works with a small team that knows its account, rather than a rotating queue of billers.

Patient statements go out on the 15th of each month, and the team fields patient billing questions directly. Larger balances can move onto coordinated payment plans. Practices that keep an in-house biller can buy coaching instead, which suits new offices setting up billing correctly from day one.

Medical Claims Solutions is a long-running cardiology billing company option with more than 20 billing and credentialing professionals on staff. Practices get direct access to the person responsible for their account, which clients cite as a main reason they stay. The team also trains in-house staff on billing best practices.

One distinctive service targets Carelon, a benefits manager many plans use for prior authorization. The firm says it has helped practices recoup thousands of dollars tied up in Carelon problems. Its receivables approach also aims to collect patient balances without damaging the doctor-patient relationship.

Avosina Healthcare Solutions began with HalaX, Dr. Alidad Arabshahi’s analytics tool that sits on top of almost any EMR. A later acquisition of a local billing and IT firm turned it into a full RCM vendor. Among the cardiology billing companies here, it leans hardest on analytics.

Avosina runs a hybrid model, with offshore staff for scale and US-based oversight and account management. Its scope reaches beyond claims into IT support, staff recruitment, and MSO development. That breadth fits practices that want one vendor for back-office operations, not only billing.

MC RevWorks is a cardiology-only billing company whose founder began as an echo tech in the cath lab. That clinical path moved into coding, compliance analysis, and risk adjustment program work over 18+ years. The result is a biller who knows what a procedure note needs before a claim exists.

Education sets this firm apart. The founder holds CPC, CPMA, CRC, and CCC credentials and has trained more than 656 providers and 100 coders and managers on documentation. A monthly education program for cardiology coders is in development for practice staff who want ongoing training.

Cardiology-Cloud is the cardiology billing company brand of WRS Health, an EHR and practice management vendor founded by ENT surgeon Lawrence Gordon, MD. The brand pairs a cardiology-specific record system with billing specialists who work only on cardiology claims, so documentation and coding stay in one place.
