California Behavioral Health Billing Services Across Complex Payment Pathways
Each service is handled according to the payer responsible for reimbursement and the clinical care represented on the claim.
Coverage & Payer Identification
Confirm active benefits and determine the correct payer pathway before billing, especially when responsibility differs between Medi-Cal, county, and commercial coverage.
Authorization & Medical Necessity
Track approvals, effective dates, service limits, and supporting documentation for behavioral health services that require payer authorization.
CPT & HCPCS Claim Accuracy
Check ICD-10-CM, CPT/HCPCS, modifiers, POS, units, and time-based behavioral health services against the clinical record before submission.
Medi-Cal & County Claim Routing
Direct applicable claims through the correct Medi-Cal, Mental Health Plan, DMC-ODS, or commercial billing pathway based on service and payer responsibility.
Payer Denials & Reconsiderations
Use CARC/RARC responses to determine why claims failed and move eligible balances through correction, reconsideration, appeal, or escalation.
Remittance & Underpayment Recovery
Reconcile 835 ERAs, contractual adjustments, short payments, and unpaid balances to identify revenue that still requires payer action.
Integrated Revenue Workflows for Behavioral Health Billing
Clinical and financial data should not live in disconnected systems. THG works across EHR, PM, clearinghouse, ERP, and reporting platforms so you can trace charges, remittances, adjustments, and payer balances without unnecessary manual reconciliation.

What California Behavioral Health Organizations Value About THG

Where California Behavioral Health Reimbursement Can Lose Value
Medi-Cal, county billing pathways, and commercial carriers can apply different rules for authorization, claim routing, documentation, and reimbursement.
Where Payment Gets Stuck
Incorrect Payer Path
A valid claim reaches the wrong billing entity or reimbursement channel.
Medical Necessity Support
The service is billed correctly, but required clinical support is incomplete.
