Summary

Connecticut HUSKY Health (Medicaid) has expanded the settings where resident physicians can provide billable services to include physician offices and medical clinics, in addition to hospitals and FQHCs. This requires specific documentation requirements, use of GC modifier, and adherence to primary care exception rules for certain E/M codes.

Action Required

Action needed
Immediately: Billing team must update system to require GC modifier for all services performed in part by residents under teaching physician supervision. Update encounter forms to remind providers to document their direct involvement in patient management and reference resident notes. Verify that resident services in physician offices and medical clinics now qualify for reimbursement if documentation requirements are met.
