Medical Billing in California: What Practices Here Face in 2026
California practices bill a payer mix that changes from county to county. Medi-Cal plan assignments change by county, Medicare runs through Noridian, and the state's commercial plans now have a hard 30 day payment clock. Knowing which rule applies to which claim is most of the work.
Medi-Cal Managed Care Plans by County
Most Medi-Cal members get care through a managed care plan, and which plan depends on the county. In single plan counties, one local plan covers Medi-Cal managed care members, with Kaiser Permanente also available in some of them. Examples include CalOptima Health in Orange County, Health Plan of San Mateo, Partnership HealthPlan of California across much of Northern California, Central California Alliance for Health in Merced, Monterey and Santa Cruz, and Alameda Alliance for Health in Alameda County. In Los Angeles County, members choose between L.A. Care and Health Net, and Health Net subcontracts half of its Los Angeles membership to Molina.
The commercial plan contracts that DHCS awarded for January 2024 set the current map in 21 counties:
- Blue Cross of California Partnership Plan (Anthem) in 14 counties, including Fresno, Kern, Sacramento, San Francisco and Santa Clara
- Health Net Community Solutions in 10 counties, including Los Angeles, San Joaquin, Stanislaus and Tulare
- Molina Healthcare of California in Riverside, Sacramento, San Bernardino and San Diego
- Blue Shield of California Promise Health Plan and Community Health Group Partnership Plan in San Diego
DHCS has extended these contracts through December 31, 2026 and says the next procurement will begin no sooner than 2029. A Sacramento practice can see four different Medi-Cal plans in one week, each with its own prior authorization list and claim edits.
Medicare in California: Noridian Jurisdiction E
CMS assigns California to A/B MAC Jurisdiction E (JE), administered by Noridian Healthcare Solutions. JE also covers Hawaii, Nevada, American Samoa, Guam and the Northern Mariana Islands. Part B claims split into two contracts, 01112 for Northern California and 01182 for Southern California, so payer setup must match the practice location.
Noridian's Facet Joint Interventions for Pain Management LCD (L38801) carries a revision effective April 16, 2026. Radiofrequency ablation requires two diagnostic medial branch blocks, each giving at least 80% sustained relief of the index pain, and coverage is limited to two RFA sessions per spinal region in a rolling 12 months. Pain Management and PM&R groups should verify both blocks are documented before an RFA claim leaves the office.
Commercial Payers and the 2026 Rules
California practices bill Anthem Blue Cross, Blue Shield of California, Health Net, UnitedHealthcare, Aetna and Cigna. Two changes matter this year.
First, Assembly Bill 3275 applies to claims received on or after January 1, 2026. Under DMHC guidance (APL 25 007), plans must pay a complete claim, or contest or deny it, within 30 calendar days. Late payment accrues interest at 15% a year. The rule covers commercial and Medi-Cal plans, so a clean claim now has real leverage behind it.
Second, Anthem Blue Cross of California planned an automatic E/M downcoding policy starting February 15, 2026. After objections from the California Medical Association and a regulator review, Anthem paused it. The CMA's June 18, 2026 update said the pause was extended through September 1, 2026. As of October 7, 2026 we found no newer public CMA update on whether the pause was extended again, so confirm the policy's current status with Anthem before relying on it. Cigna's R49 policy, in effect since October 1, 2025, already adjusts 99204, 99205, 99214, 99215, 99244 and 99245 claims. Our BCBS downcoding 2026 state by state breakdown tracks where Blue plans stand.
How WeBill Health Defends California Practices
The 30 day clock only helps a practice whose claims are complete on the first pass. WeBill Health maintains internal payer rule libraries organized by specialty and by carrier, built and updated by experts who work claims in your specialty every day. Every claim receives human pre submission review against them before it goes out. In California that covers each county's Medi-Cal plan, Noridian JE LCDs and commercial E/M rules, across more than 500 payer rulesets.
Our commitments are a 98% clean claim rate, a 48 hour submission guarantee, a 40% A/R reduction within 90 days and 7 to 14 day reimbursement velocity.
Joining Medi-Cal plans and commercial networks starts with enrollment that stays current. Revenue Velocity Credentialing delivers 40% faster credentialing enrollment with 24/7 CAQH and PECOS lifecycle monitoring, and you get direct access to your billing team throughout.
California Medical Billing FAQ
Which Medi-Cal plan will my patients have?
It depends on the county. Single plan counties have one local plan, Los Angeles has L.A. Care and Health Net, and 21 counties use commercial plans such as Anthem, Health Net and Molina under the 2024 DHCS contracts.
Who is the Medicare contractor for California?
Noridian Healthcare Solutions administers Jurisdiction E. Part B uses contract 01112 for Northern California and 01182 for Southern California.
How fast must California health plans pay claims in 2026?
For claims received on or after January 1, 2026, AB 3275 requires plans to pay a complete claim within 30 calendar days. Unpaid claims accrue 15% annual interest. It applies to commercial and Medi-Cal plans.
Is Anthem Blue Cross downcoding E/M claims in California?
Anthem paused its planned E/M downcoding policy after CMA objections, and the CMA's June 18, 2026 update said the pause was extended through September 1, 2026. As of October 7, 2026 no newer public CMA update was available, so confirm the current status with Anthem.
