Claims built for California's own rules.
A law now requires a licensed physician to review every AI-assisted denial. A new gold-carding program phases out prior authorization for high-approval services by 2028. A statewide target caps health spending growth at 3.5%. A2Z Billings builds coding, credentialing, and denial management around exactly these rules.

Five Medi-Cal delivery models decide who a practice bills, and how.
Medi-Cal, California's Medicaid program, covers roughly 15.2 million residents through five delivery models: County Organized Health Systems, Two-Plan, Geographic Managed Care, Regional, and single-plan counties such as Imperial and San Benito. A 2024 statewide procurement narrowed the commercial roster to five plans (Anthem Blue Cross, Health Net, Molina Healthcare, Blue Shield Promise, and Community Health Group) after Aetna exited the program entirely. Kaiser Permanente runs a separate direct Medi-Cal contract in 32 counties under SB 510 and AB 2724.

What actually holds up California claims
AI Oversight
A licensed physician has to sign off Under SB 1120, effective January 1, 2025, AI tools cannot independently deny, delay, or modify a claim based on medical necessity. A licensed physician has to review it.
GOLD-CARDING
Earning an exemption takes 36 months SB 306 lets a health professional skip prior authorization on services approved 90% of the time, but only after 36 months of contracted history with that insurer.
COST GROWTH TARGET
A 3.5% ceiling on spending growth The Office of Health Care Affordability's statewide target holds spending growth to 3.5% for 2025 and 2026, with seven high-cost hospitals capped at 1.8%.
WORKFORCE WAGES
Wages climbing on a fixed schedule SB 525 pushed the health care worker minimum wage toward $25 an hour on a schedule that runs through 2028, depending on facility size.
PROCUREMENT RESET
A 2024 procurement changed the map DHCS's statewide Medi-Cal managed care procurement replaced the commercial plan roster in most counties and dropped Aetna from the program entirely.
DUAL REGULATORS
DMHC or CDI, depending on the plan DMHC oversees roughly 30 million Californians in HMO and most PPO plans. CDI regulates indemnity and some PPO insurers under a separate code.
Every friction point, mapped to a service
Services, built around how California pays
Medical Billing
Claims sequenced to clear DMHC and CDI edits on the first submission, not after a rejection.
Medical Coding
Coders current on SB 1120's AI-review requirements and Medi-Cal's coding updates.
Credentialing
Enrollment tracked through the 2024 Medi-Cal procurement reset and each plan's own panel rules.
Revenue Cycle Management
Oversight built for a market now reporting against the Office of Health Care Affordability's cost growth target.
Eligibility Verification
Checks run against the correct one of California's five Medi-Cal delivery models before the visit.
Prior Authorization
Requests tracked toward SB 306 gold-card eligibility, not just submitted and forgotten.
Denial Management
Root-cause review for denials that must, by law, carry a physician's signature under SB 1120.
Payment Posting
Reconciliation against Medi-Cal, DMHC, and CDI fee schedules side by side.
AR Follow-Up
Persistent follow-up through Independent Medical Review when a California payer won't budge.
Specialty billing, with the California-specific friction points
Behavioral Health & Psychiatry
Billing aligned to CalAIM's statewide documentation standard for specialty mental health and substance use services.
Cardiology & Oncology
Coding for high-cost procedures still outside SB 306's 90%-approval exemption, where prior authorization still applies.
Urgent Care & Family Medicine
High-volume claims checked against the correct Medi-Cal delivery model at every visit, not just at enrollment.
Physical Therapy & Pain Management
Authorization renewals tracked against each plan's own approval-rate data, not a single statewide rule
Orthopedics & Neurology
Plan-specific authorization cycles, since gold-card eligibility is measured per service category, not per practice.
Gastroenterology, Dermatology & Radiology
Coders who track imaging-heavy authorization rules, still the largest single category of review requests.

The rules practices are tracking heading into 2028
California set its statewide cost growth target at 3.5% for 2025 and 2026, moving to 3.0% by 2029. SB 525 is still raising the health care worker minimum wage toward $25 an hour on a schedule that runs past 2028. SB 306's gold-carding exemption doesn't take effect until January 1, 2028, and plans have to report their approval-rate data by the end of 2026 first. Tracking three deadlines across three different agencies is why practices bring in A2Z Billings rather than hand it to staff who are already busy with patient care.
Common questions from California providers
How does SB 1120 change who reviews an AI-assisted denial?+
Effective Jan 1, 2025, any AI-assisted denial, delay, or modification based on medical necessity must be reviewed and decided by a licensed physician or qualified clinician AI alone can't decide, and the denial notice must name a directly reachable reviewer.
When does SB 306's gold-carding exemption actually take effect?+
Enacted Oct 2025, but the actual prior-auth exemption doesn't start until January 1, 2028 2026-27 is just data reporting and publishing the qualifying-services list.
How does the 2024 Medi-Cal managed care procurement affect credentialing?+
Pushed standardized credentialing, a single UM framework, and common provider-directory formats but plan churn across counties (Aetna exit, Health Net LA changes) forced re-credentialing for affected providers.
What does the Office of Health Care Affordability's cost growth target mean for billing and reporting?+
Doesn't change billing codes — it adds a mandatory annual Total Health Care Expenditure data-reporting obligation, with graduated enforcement starting 2027-28 if growth exceeds 3.5%→3%.
