Summary
Connecticut Medicaid (HUSKY Health) has established specific documentation and billing requirements for services performed by residents in hospital settings. Teaching physicians must use the GC modifier and provide detailed documentation showing their supervision and participation in resident-performed services.
Action Required
Immediately: Teaching physicians must add GC modifier to all claims for services performed in part by residents. Update billing system to require GC modifier and statement 'This service has been performed in part by a resident under the direction of a teaching physician.' Providers must document their physical presence during key portions of procedures and their review/supervision of resident work. Update encounter forms and EMR templates to include required documentation elements for teaching physician participation.
