frequently asked questions

How do I enroll as a Medi-Cal mental health provider in California?

You must apply through the DHCS PAVE portal, submit required documents, pass background checks, and await state and county plan approval before providing services.

Why are Medi-Cal claims often denied in California?

Denials often stem from missing prior authorization, wrong CPT/HCPCS codes, incomplete CalAIM documentation, or errors in eligibility verification through PAVE or county behavioral health plans.

How does CalAIM affect mental health billing in California?

CalAIM requires new documentation standards, outcome-based reporting, and bundled billing for specialty mental health services. Providers must align notes, diagnosis codes, and care plans with DHCS guidelines.

Why is credentialing delayed with Medi-Cal in California?

Delays happen due to incomplete PAVE submissions, fingerprinting issues, or backlogs at DHCS and county mental health plans like LA County DMH. Careful documentation prevents rejections.

What billing issues do providers face with L.A. County DMH?

Common issues include complex claiming portals, strict service note compliance, and rejections for not meeting CalAIM clinical documentation standards. LA County DMH requires precise alignment with its fee schedules.

How can San Diego behavioral health providers avoid payment delays?

Submit claims through Optum San Diego’s system promptly, verify Medi-Cal eligibility, and ensure proper CPT code usage with CalAIM documentation to prevent claim denials.

Why are Alameda County mental health claims frequently audited?

Alameda County Behavioral Health often audits providers for service note accuracy, diagnosis alignment, and CalAIM documentation compliance. Detailed, defensible records reduce audit risks.

How do California behavioral health providers handle Medi-Cal managed care plans?

Providers must follow each MCP’s portal rules (e.g., Anthem Blue Cross, Blue Shield Promise, Partnership HealthPlan). Errors in CPT coding or authorization requests cause most denials.

What issues arise with Medicare and Medi-Cal dual-eligible patients?

Coordination of benefits is challenging. Medicare pays primary, Medi-Cal covers secondary, but incorrect claim sequencing or mismatched codes often leads to denials.

How can California telehealth mental health providers bill Medi-Cal?

Submit synchronous telehealth claims with proper POS 02 or 10, use approved CPT/HCPCS codes, and confirm coverage under Medi-Cal’s telehealth parity laws.

What challenges exist for SB 803 peer support billing in California?

Peer support specialists must be certified through CalMHSA, enrolled in Medi-Cal, and bill using specific HCPCS codes. Delays occur when county systems aren’t updated.

Why are prior authorizations a hurdle in California behavioral health billing?

Plans like Kaiser, Anthem, and LA Care often require prior authorization for therapy beyond initial sessions. Delays or incomplete clinical notes cause approval denials.

How do mental health providers in California deal with retroactive Medi-Cal eligibility?

Claims must be resubmitted within 12 months of eligibility determination. Providers should track retroactive eligibility through the Medi-Cal Eligibility Data System (MEDS).

How can small private practices in California manage billing compliance?

They should use certified EHRs, outsource billing to experts familiar with DHCS rules, and regularly audit claims to avoid compliance violations under CalAIM.

What is the biggest billing challenge with California’s county-based mental health system?

County-specific requirements cause inconsistencies. LA, Alameda, and Riverside all have different fee schedules, portals, and authorization rules, creating major billing complexity for providers.

How does CalMHSA affect billing for behavioral health providers?

CalMHSA oversees certification, training, and infrastructure for peer support and certain behavioral health initiatives. Providers must follow its updates to align billing processes.

Why are Medi-Cal reimbursements often low for mental health services?

Medi-Cal reimbursement rates in California are among the lowest nationally. Providers must optimize billing accuracy and appeal underpaid claims to sustain revenue.

What are DHCS audit risks for behavioral health providers?

Risks include missing progress notes, improper diagnosis coding, and non-compliance with CalAIM documentation standards. DHCS audits often focus on medical necessity and time spent.

How can California telehealth providers handle county mental health billing?

Counties like LA and San Diego require telehealth claims to meet documentation and service note standards identical to in-person care. Misaligned notes trigger rejections.

What compliance issues arise with California’s mental health parity laws?

Insurers must cover behavioral health at parity with physical health. Denials for “not medically necessary” can be appealed under state parity protections.Insurers must cover behavioral health at parity with physical health. Denials for “not medically necessary” can be appealed under state parity protections.

What is prohibited balance billing for Medi-Cal members?

Medi-Cal prohibits charging members extra for covered services, including copays, coinsurance, or differences between billed and contracted rates. Violations risk provider sanctions or termination.

When can providers start billing after Medi-Cal approval?

You may bill once DHCS issues a Welcome Letter and Provider Identification Number (PIN). Claims submitted before approval are rejected.

How should providers handle “problem lists” under CalAIM documentation redesign?

Maintain a comprehensive problem list that includes diagnoses, risk factors, and co-occurring conditions. Document using ICD-10-CM codes, ensuring accuracy beyond the primary diagnosis.

What billing rules apply for Community Health Worker (CHW) services under Medi-Cal?

CHW services must be documented for duration, scope, supervision, and billed using approved CPT/HCPCS codes under an enrolled supervising provider’s NPI.
