Some distinctive rules govern the billing of California-based healthcare providers. Here is what our team manages for you amid the ever-changing billing rules:
As per the Medi-Cal provider manual, the claims under Medi-Cal must be received within the six months following the month of service. There are some exceptions for the delays. Our billing team tracks every encounter and builds a workflow that files claims within this limit.
Effective January 1, 2026, AB 3275 requires all California health plans and insurers to pay, contest, or deny claims within 30 calendar days. The rule applies uniformly, including to HMOs and Medi-Cal managed care plans, and late payers owe interest. We track every claim against the current rules and help you get paid.
California has two separate surprise-billing rules with two separate dispute paths. AB 72 covers state-regulated plans, while the federal No Surprises Act covers self-funded and other federally regulated plans. When an out-of-network payment dispute arises, our team identifies which rule applies and prepares the documentation for that process.
California plans must resolve disputes within 45 working days. We file disputes accurately, keep track of the deadlines, and escalate to regulators when necessary.
The requirements of California’s Confidentiality of Medical Information Act are stringent as compared to federal law. Our mechanism of communications follows both standards.
California is the only state where two regulators oversee the patient’s health plan. Department of Managed Health Care (DMHC) regulates most managed care enrollees, including the Medi-Cal managed care under the Knox-Keene Act. PPO and indemnity policies fall under the California Department of Insurance (CDI). Our experts verify these issues at the time of eligibility to ensure the dispute goes to the right place.
Patient's plan - Which regulator oversees it?
HMOs and most managed care, including Medi-Cal managed care
Knox-Keene Act rules
Disputes and complaints go through the plan's PDR process then the DMHC
Most PPO and indemnity insurance policies
Insurance Code rules
Disputes and complaints go to the California Department of Insurance
different dispute paths We identify the regulator at eligibility — so escalations land where they have teeth
Our billers and coders are knowledgeable about the unique payer mix in California. We work with:
Most Medi-Cal patients are enrolled in managed care plans under CalAIM, a Medicaid reform initiative. Each plan has its own portal and appeal windows. We take care of these things along with prior auth rules to verify and bill accurately.
The entity that pays for the medical claim is not the health plan in much of California. A delegated IPA (Independent Practice Association) or medical group under capitation pays for the claim. Mismanaging the route of these claims is one of the most common denial reasons. As a billing company in California, our experts manage these routes to help reduce claim denials.
We help you get reimbursed from major commercial payers like UnitedHealthcare, Kaiser, Health Net, Anthem Blue Cross, Blue Shield of California, Aetna, and Cigna.
We help you receive payments for Medicare Part B claims through California’s Medicare Administrative Contractor (MAC), with LCD-aware coding for coverage rules in the state of California.
We check your claims against the deadlines that matter in Texas and show you where revenue is slipping. Find out with a free billing audit.
Get a Free Claims ReviewOur medical billing services in California follow a more organized method so that errors can be minimized, claims can be paid accurately, and service providers can get their payments on time. Every step is considered carefully to ensure the revenue cycle performs well. We have developed a comprehensive process for all the procedural steps involved in CA medical billing.
To avoid delays or denials in billing, we collect patient information, validate insurance eligibility, and report any coverage issues as early as possible.
Our team of skilled coders analyzes the clinical records and applies the proper CPT and ICD codes to guarantee claim submission according to the relevant regulations.
Claims are checked and processed properly to ensure that they meet all payer requirements and claim submission is done promptly.
The process includes payment processing as well as adjustment and denial of claims and payments. The result is the creation of accurate records and the transparency of the financial health status of a practice.
Our dedicated team of accounts receivable experts finds the root cause of denials. They correct the claims and file appeals within the payer deadlines. Our experts pursue aging A/R until it is resolved.
With the aid of comprehensive reports and performance data, we enhance workflows, firm up collections, and optimize California healthcare medical billing processes.
Precision coding is critical in the reimbursement process. We have an accomplished team of coders certified by AAPC or AHIMA with rich experience in CPT, ICD-10-CM, and HCPCS coding protocols.
In addition, certified coding staff ensure that claims are reviewed accurately, which leads to fewer coding mistakes, reducing claim denials and complying with the dynamic rules of healthcare. Certified coders guarantee that every unit is coded correctly, thus maximizing the reimbursement possibilities and minimizing the risk of mistakes.
The importance of certified coders:
A Behavioral Health Practice's Journey to a Stable Revenue Cycle
Our team took over the practice's billing and credentialing, reviewed every open case individually rather than working from batch reports, and trained the practice's staff on current behavioral health coding rules. Billing went from a recurring problem to a managed process.
"I am impressed with their promptness to respond to any inquiries, with the time they dedicate to reviewing each one of the cases, and with their willingness to educate me and my staff about the ever-changing rules of medical billing and the best use of coding. This is a company I trust with my billing needs."

The Medi-Cal provider manual shows that the claims must be received within six months following the month of service. For instance, if the services are provided on January 15, the claim must be received prior to July 31 to avoid claim denial.
Under AB 3275, which took effect on January 1, 2026, the insurers and health plans in California must pay or deny claims within 30 days. It is a uniform rule for HMOs and Medi-Cal managed care plans. Our medical billing teams track every claim against every deadline.
The Department of Managed Health Care regulates HMOs and most managed care plans (including Medi-Cal managed care) under the Knox-Keene Act; the California Department of Insurance regulates most PPO and indemnity policies. Payment deadlines are now unified, but dispute and complaint processes differ. We identify the patient's regulator before filing disputes.
The financial responsibility for some services lies with IPA and capitated medical groups instead of health plans. This division determines the route of the medical claims in California. If it is sent to the wrong entity, it gets denied. We help maintain accurate routes of the medical claims to achieve maximum reimbursements.
Yes. We bill both fee-for-service Medi-Cal and the managed care plans that cover most Medi-Cal patients under CalAIM, each with its own portal, prior-authorization rules, and appeal deadlines.
We charge a percentage of collections. No setup fees and no hidden charges. Pricing depends on your claim volume and specialty; contact us for a customized quote.

Hello,
I am writing this email to express our appreciation of the MedCare MSO’s team and all they have done for our business at RLT. In the past year, we have experienced tremendous improvements within our billing and claims department that we have entrusted MedCare MSO to manage. We went from having over $100k in uncollected/billed claims to now reaching near $100k in collection some months.
We are also happy to express our thankfulness that MedCare MSO is now helping us acquire new contracts with different insurance companies. This will in effect benefit everyone involved, allowing us to expand our services and provide more resources for our staff/business partners.
Please note special appreciation for the following:
