CPT 98004 Telehealth E/M Reimbursement & Policy

CPT code 98004 designates an established patient evaluation and management visit conducted via synchronous audio–video technology, involving straightforward medical decision making or at least 10 minutes of provider time on a single date. This telehealth-specific E/M code reflects the continued integration of virtual care into ambulatory practice and is relevant nationally as payers and regulators refine coverage and billing policies for remote patient encounters.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical purpose, typical site of service, and common billing considerations. The publication summarizes payer coverage patterns, common modifiers used with telehealth E/M services, and comparators to related E/M codes where available.

Clinical Context

A patient established with a primary care clinic requests a telehealth follow-up for a stable chronic condition. The patient is at home and connects via synchronous audio–video technology. The provider documents an evaluation and management interaction that involves straightforward medical decision making and spends at least 10 minutes of total time on the encounter on a single date. Typical reasons include medication refills with brief assessment of adherence and side effects, routine review of stable hypertension or diabetes control without new complications, counseling on lifestyle measures, or discussion of recent laboratory results that do not require complex decision making. The clinical workflow includes patient check-in in the portal, verification of identity and location, review of the chart and recent results, synchronous video visit with focused history and limited exam as feasible, documentation of time and decision making, and electronic prescribing or orders as appropriate. Telehealth platform support staff may assist with connectivity, and the visit is coded using 98004 for the established patient synchronous audio–video E/M meeting the described time and complexity criteria.
