California is the largest and most complex billing market in the country. Medi-Cal runs through dozens of county-based managed care plans, each with its own authorization rules and filing windows, while commercial payers and Medicare Advantage add their own layers on top. A billing process that works in one county can fail in the next.
MedPlus RCM provides medical billing, coding, credentialing, and denial management for California practices of every specialty, built around the state’s actual payer landscape, not a generic national workflow.
California’s payer landscape
California’s Medicaid program is Medi-Cal, delivered largely through managed care plans that vary by county. The highest-volume Medi-Cal plans for most practices include L.A. Care Health Plan, Health Net, Anthem Blue Cross Partnership Plan, Blue Shield of California Promise Health Plan, Molina Healthcare of California, CalOptima Health, Inland Empire Health Plan (IEHP), and Partnership HealthPlan of California. Commercial coverage runs through Anthem Blue Cross, Blue Shield of California, Health Net, Aetna, UnitedHealthcare, and Cigna, alongside Medicare and Medicare Advantage plans.
That fragmentation is where California revenue leaks. A claim billed to the wrong plan, an authorization secured from the wrong entity, or a filing window missed because the plan’s rule differed from the last one, each is a preventable denial. MedPlus RCM verifies the plan of record and the plan’s rules before the claim goes out, so California’s complexity stops being a denial source.
What MedPlus RCM handles for California practices
- End-to-end medical billing. Charge entry, claim scrubbing, submission, payment posting, and patient billing, the full cycle.
- Medical coding. Certified coders assign current ICD-10, CPT, and HCPCS codes matched to your documentation and specialty.
- Provider credentialing and enrollment. End-to-end enrollment with Medi-Cal plans, commercial payers, and Medicare, plus re-credentialing maintenance.
- Denial management and recovery. Every denial investigated to root cause, corrected, and appealed with documentation.
- A/R recovery. Aged and outstanding balances audited and pursued, including balances already written off where the appeal window is still open.
- Financial reporting. Clean claim rates, collections, denial patterns, and A/R aging visible by payer and provider.
