Summary
Illinois Medicaid has established new requirements for group psychotherapy coverage in clinic settings, limiting patients to maximum 2 sessions per 7-day period and requiring sessions be performed by psychiatrists with specific residency certification on file with the state.
Action Required
Immediately: Billing team must implement session frequency tracking to prevent billing more than 2 group psychotherapy sessions per patient in any 7-day period across all providers. Ensure all physicians rendering group psychotherapy have HFS 3882 Psychiatric Residency Certification on file with Illinois HFS or claims will be rejected with code G98. Update billing edits to flag frequency violations (rejection code K01). Verify group therapy sessions are minimum 45 minutes, limited to 12 patients, use ICD-9 codes 290-319, and include required documentation elements in medical records.
