5 California laws that affect your billing every day
California has some of the most protective medical billing regulations in the country. From AB 72 surprise billing rules to Knox-Keene managed care oversight, here is what applies to your practice and how our outsourced billing services handle each.
Surprise Billing Ban
Out-of-network doctors at in-network facilities cannot balance bill patients. Patients pay only the in-network cost-sharing amount. Applies to non-emergency services at in-network hospitals, ambulatory surgery centers, and labs.
Managed Care Oversight
California managed care plans (HMOs, PPOs, Medi-Cal MCOs) are regulated by the Department of Managed Health Care (DMHC). Includes provider network adequacy, timely access standards, and grievance procedures.
Timely Payment Requirements
Insurers must pay clean paper claims within 45 days and clean electronic claims within 30 working days. Late payment triggers 15 percent penalty per year plus interest. Applies to all commercial payers regulated by CDI.
Medi-Cal Enrollment Timeline
California Medi-Cal provider enrollment through the Department of Health Care Services (DHCS) typically takes 90 to 120 days. Requires PAVE 3.0 portal application, license verification, disclosure statements, and background checks.
Transgender Health Care Coverage
California health plans must cover medically necessary transgender health care services without discrimination. Includes hormone therapy, gender-affirming surgeries, mental health services, and voice therapy. Denials based on gender identity are prohibited.

How a San Diego orthopedic group recovered $520K in aged AR
The Situation
A 6-provider orthopedic group in San Diego came to CureMed in Q2 2025 with 78 days of aged AR and a mounting backlog of Anthem Blue Cross California denials on spine surgery cases. Their previous billing company was submitting claims without proper prior authorization documentation for Anthem BC and failing to appeal Blue Shield California denials within the timely filing window. Workers compensation claims were sitting unresolved for 90 or more days. Aged AR had grown to over $600K in unresolved balances.
What We Did
Within the first three weeks, we audited 120 days of aged AR and identified $520K in recoverable revenue across Anthem BC, Blue Shield CA, Kaiser Permanente coordination cases, and workers compensation claims. We deployed our California-specific denial workflow: prior authorization tracking for spine and joint replacement procedures, direct Blue Shield California portal integration, DMHC complaint escalation for Knox-Keene violations, and workers compensation appeals through the California Division of Workers Compensation portal.
The Result After 90 Days
The practice added a seventh orthopedic surgeon within the second quarter without hiring additional billing staff. Monthly collections grew 28 percent. Anthem BC denial rate on spine surgery dropped from 24 percent to 9 percent. Workers compensation resolution time dropped from 90+ days to 32 days on average.

Common questions about medical billing services in California
Do you serve small practices in California or only large ones?
We serve solo practitioners to mid-size groups across California. This includes single-provider dermatology practices in San Francisco and 20-provider cardiology groups in Los Angeles. Our 4.99 percent flat rate applies whether you bill $30,000 or $300,000 per month.
How does CureMed handle California Prompt Payment Act violations?
Every claim we submit is tracked against the California payment windows. Electronic claims must be paid within 30 working days and paper claims within 45 days. When a payer misses the deadline, we automatically file for the 15 percent annual penalty plus interest. Most billing companies leave this money on the table. We recover it.
Which California Medi-Cal MCOs does CureMed work with?
We work with all major California Medi-Cal managed care organizations. This includes LA Care Health Plan, Health Net, Molina Healthcare California, Anthem Blue Cross Medi-Cal, Blue Shield Promise Health Plan, and Kaiser Permanente Medi-Cal. Our dedicated California Medi-Cal team handles prior authorizations, appeals, and DHCS PAVE 3.0 portal submissions.
How long does provider credentialing take in California?
Commercial payers: 60 to 90 days on average. California Medi-Cal through DHCS PAVE 3.0: 90 to 120 days. Medicare: 60 to 90 days. We manage the entire application through go-live, and can start billing on day one under a supervising provider while credentialing is in process.
How does CureMed handle California AB 72 surprise billing rules?
AB 72 requires that patients pay only in-network cost-sharing when seeing out-of-network doctors at in-network facilities. Our pre-service eligibility verification identifies these patients before service. We handle the correct billing pathways to ensure compliant reimbursement from insurers under AB 72 rate structures, avoiding patient collection disputes.
Can you help my California practice recover aged AR?
Yes. This is one of our specialties. We offer a free 90-day AR audit for California practices. Our team identifies recoverable claims, files appeals within California-specific timely windows (which vary by payer between 90 and 180 days), and recovers money that most billing companies wrote off. Average recovery in our first California AR audits ranges from $220,000 to $520,000 per practice.
