Quick Explanation
Denial code MH65 indicates that the payer has rejected the claim because the required documentation or billing code for a standardized substance abuse screening is missing. Payers mandate these screenings as a prerequisite to establish medical necessity before reimbursing for subsequent substance use disorder treatments or behavioral health services.
Common Causes for MH65
Denials with code MH65 typically happen for the following specific reasons:
- Failure to perform or document a standardized substance abuse screening tool (such as AUDIT, DAST, or CRAFFT) prior to initiating behavioral health treatment.
- Omitting the appropriate screening HCPCS/CPT codes (such as G0442, G0443, 99408, or 99409) on the claim form when billing for related therapy or evaluation services.
- Insufficient clinical documentation in the medical record to support that a structured Screening, Brief Intervention, and Referral to Treatment (SBIRT) service was fully executed.
- Billing for subsequent intensive outpatient (IOP) or substance use disorder (SUD) program services without the required baseline screening on file for the benefit period.
How to Prevent MH65 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Integrate mandatory EHR alerts and templates that prompt providers to complete and score standardized screening tools during intake and annual behavioral health visits.
- Configure billing software edits to flag claims for substance-related treatments that lack a corresponding screening code or documentation attachment.
- Provide regular clinical documentation training on the specific requirements for SBIRT billing, including documenting the exact tool used, scoring results, and intervention time.
- Verify payer-specific policies regarding the required frequency, acceptable screening tools, and billing codes for substance abuse preventive services.
