HCPCS Level II code G9978 identifies a remote in-home evaluation and management (E/M) visit for a new patient, specified for use within Medicare’s BPCI Advanced bundled payment episodes. The code denotes a brief, problem-focused telemedicine encounter delivered in real time with interactive audio and video, including a problem-focused history, problem-focused exam, and straightforward medical decision making—typically about 10 minutes. This designation matters nationally as programs that bundle payments increasingly rely on precise coding to track episode-based services and ensure care coordination across settings.

Key payers covered in this summary include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of what the code represents, the clinical context for its use in bundled payment episodes, and the operational elements that differentiate it from other E/M and telemedicine codes. The publication also outlines common billing modifiers and payer considerations where available, and notes where input data is limited. The goal is to provide clinicians, billing staff, and policy analysts with a clear, national-level briefing on the code’s purpose, expected service setting, and relevance in value-based payment models.
