Summary & Overview
CPT 99348: Home/Residence E/M Visit for Established Patients
CPT code 99348 covers evaluation and management visits for established patients conducted in a home or private residence when the encounter involves low medical decision making or when the clinician documents at least 30 minutes of total time on a single date. This home-based E/M code is important nationally as home visits remain a critical access point for patients with mobility, transportation, or frailty challenges and for clinicians delivering longitudinal, in-person care outside clinic walls.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find national context on the clinical service represented by the code, how time and decision-making thresholds define its use, and the typical site of service for billing. The publication outlines benchmarks and utilization patterns, common modifier use where documented, and policy considerations affecting coverage and coding practice.

Clinical & Coding Specifications
Clinical Context
An established adult patient receives a scheduled home visit by a primary care provider for management of chronic conditions. The visit occurs at the patient’s private residence and involves a focused history, targeted physical exam, medication reconciliation, review of recent labs and home monitoring (blood pressure, glucose), and coordination of community services. The encounter requires low medical decision making and the clinician documents at least 30 minutes of total time spent on the date of service, including face-to-face time, care coordination phone calls, and chart review. Typical scenarios include routine follow-up for controlled heart failure, hypertension, diabetes mellitus with stable control, medication adjustments that do not require complex management, or care for a mobility-limited patient who cannot travel to the clinic. The workflow includes pre-visit review of the patient’s record, arrival and home-based assessment, documentation of findings and time, communication with pharmacists or family caregivers as needed, and electronic submission of the visit note and billing with appropriate modifiers and diagnoses.
