Medical Billing and Coding Services Scaled for California Practices
Every service below is delivered by our own billing team, not routed through a platform you have to manage yourself.
Medical Coding Services
Specialty-specific CPT, ICD-10, and HCPCS coding that reflects how California's dozens of payer combinations actually adjudicate a claim.
Medical Billing Services
Full-cycle claims submission and payment posting built around Medi-Cal, Kaiser Permanente, Anthem Blue Cross, and Blue Shield of California filing rules.
Consultation and
Audit
A structured review of your current billing performance, denial patterns, and coding accuracy before we take over a single claim.
Denial Management
Denial management services built around California's highest-volume failure points, from Medi-Cal routing errors to Knox-Keene appeal deadlines.
Revenue Cycle Management
End-to-end oversight from patient registration through final payment, keeping AR days low and cash flow predictable.
Credentialing and Enrollment
Payer enrollment and re-credentialing across Medi-Cal managed care plans, Kaiser, Anthem, and Blue Shield of California, managed remotely.
Patient Billing and Collections
Clear, accurate patient statements and a collections process that protects your practice's reputation while recovering what's owed.
Eligibility and Verification
Real-time eligibility and benefits verification before the appointment, not discovered after a claim has already been filed.
California’s Complex Payer Landscape
California runs the largest and most fragmented Medicaid program in the country. Medi-Cal covers roughly 15 million residents across all 58 counties, but which plan a practice bills through depends entirely on the county, since the state uses five different managed care models: Two-Plan, County Organized Health Systems, Geographic Managed Care, Regional, and Single-Plan.
On the commercial side, Kaiser Permanente’s closed, integrated network leads statewide enrollment, with Anthem Blue Cross and Blue Shield of California as the only two carriers offering PPO plans on Covered California. Two regulators split oversight, the Department of Managed Health Care for most HMOs and the Department of Insurance for the rest, each enforcing its own claims and network rules.

Where California Claims Most Often Go Wrong
County-by-County Medi-Cal Routing
Which Medi-Cal plan a claim goes to depends on the patient's county and delivery model. A workflow built for a Two-Plan county can misfire completely in a County Organized Health System county.
Kaiser's Closed-Network Model
Kaiser Permanente functions as both payer and provider, so claims and referrals for Kaiser members follow a different path than standard fee-for-service billing with any other California carrier.
Two Regulators, Two Rulebooks
Whether a plan falls under the Knox-Keene Act or Department of Insurance rules changes which prompt-payment and appeal deadlines apply to a denied claim.
Scale Multiplies Small Errors
California's size means even a small error rate compounds fast. A practice billing across multiple counties and payer types needs coding accuracy that holds at scale.
Why California Practices Partner With Thrive Instead of a Local Biller
A payer map this fragmented rewards a team that treats every county and plan type as its own rule set, not a single statewide template.
Specialist, not local vendor
A team, not a software platform
Remote credentialing, no local office needed
The same verified standards, everywhere
