Cardiology Medical Billing Services in California
AMS Solutions provides specialized cardiology medical billing for California practices — Los Angeles, San Francisco, San Diego, Sacramento, and statewide. Our AAPC-certified billers handle the full cardiology code set (93451-93461 cath, 92920-92944 PCI, 93306-93308 echo, 93619-93655 EP) and the California payer mix that other billing companies miss.
California-specific payer landscape
California cardiology billing crosses Medi-Cal Managed Care, commercial Blue Shield and Anthem, Kaiser (when out-of-network), UnitedHealthcare, Cigna, and Aetna. Noridian is the MAC for CA Medicare Part B with its own LCDs for cardiac imaging and EP.
Where California cardiology revenue leaks
- Medi-Cal Managed Care prior-auth denials on advanced cardiac imaging (cardiac MRI, CCTA)
- Missed 26/TC splits on echo and stress testing at hospital outpatient departments
- Same-day cath + E/M bundling without Modifier 25
- 21-day Medi-Cal claim submission window — late = denied
- CTO PCI (92943-92944) documentation gaps
What AMS handles for California practices
- Pre-encounter eligibility verification and benefit checks
- Coding, charge entry, and claim submission
- Denial management and appeals (we don’t write off — we fight)
- A/R follow-up and patient statements
- Monthly reporting tied to your practice management system
