Medical Billing Built for California Healthcare Providers
Medi-Cal, California's Medicaid program, is administered by the Department of Health Care Services but actually delivered through county-based managed care models, so the payer of record changes by county — L.A. Care Health Plan and Health Net in Los Angeles County, Inland Empire Health Plan in Riverside/San Bernardino, San Francisco Health Plan in San Francisco, and so on. California also runs a dual regulatory system most states don't have: HMOs fall under the Department of Managed Health Care (Knox-Keene Act), while PPOs and indemnity plans fall under the Department of Insurance — two different rulebooks, two different complaint processes. Add Kaiser Permanente's integrated payer-provider model, which behaves differently than a standard commercial payer, and California billing requires county- and plan-specific knowledge that a generic RCM vendor usually doesn't have.
Whether you're in Los Angeles, San Francisco, San Diego or anywhere else in California — ZenoMedix RCM provides the same certified billing expertise with deep knowledge of local payer rules and California Medicaid requirements.

California Billing FAQ
Yes. Medi-Cal is delivered through county-based managed care, so a Los Angeles County patient is typically billed through L.A. Care Health Plan or Health Net, while a Riverside or San Bernardino patient runs through Inland Empire Health Plan. We confirm the correct county plan before submitting rather than guessing.
For HMO plans regulated under the Knox-Keene Act, California's Department of Managed Health Care requires reimbursement within 45 working days of a clean claim. We track claim aging against that deadline so late payments get flagged and followed up rather than written off.
Yes. Kaiser is both the insurer and, often, the provider network, which changes how claims and authorizations flow compared to a standard commercial payer. Our California coders handle Kaiser claims alongside Anthem Blue Cross, Blue Shield of California, and Health Net.
It can. AB 72 limits what out-of-network providers can bill patients for non-emergency services performed at an in-network facility, shifting more of the reimbursement conversation to the payer directly. We build claims and appeals around that rule rather than defaulting to patient balance billing.
We serve California practices statewide — Los Angeles, San Francisco, San Diego, San Jose, and everywhere in between — with the same certified coding team regardless of metro size.
