Summary & Overview
HCPCS M1426: Telehealth Encounter, Virtual Visit
HCPCS Level II code M1426 identifies encounters conducted via telehealth, representing remote clinical interactions between patients and providers. As telehealth has become an integral modality of care delivery, a clearly defined HCPCS code for virtual encounters supports consistent billing, administrative tracking, and policy alignment across payers. Nationally, telehealth coding affects access to care, claims processing, and program oversight.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what M1426 represents, how it is used for telehealth service lines, and why standard coding matters for reimbursement and reporting. The publication summarizes benchmark considerations and policy context relevant to telehealth encounters, highlights where payer guidance commonly aligns or diverges, and provides clinical context for typical telehealth use.
The content is intended for a national audience of billing professionals, compliance officers, and health policy analysts seeking a practical reference on HCPCS Level II code M1426, including operational implications and areas where payers may issue specific billing guidance. Data not available in the input will be signposted where applicable.

Clinical Context
A patient with a non-urgent follow-up for a chronic condition connects with their primary care clinician via a scheduled telehealth video visit billed under M1426. The patient is an adult with controlled hypertension and type 2 diabetes, reporting intermittent elevated home blood pressures and asking medication clarification. Prior to the visit, the medical assistant verifies patient identity, documents consent for telehealth, updates medication list and recent vitals entered by the patient (home blood pressure readings, weight, and glucose logs). The clinician conducts the encounter via secure video, reviews the home monitoring data, performs a focused virtual assessment (visual inspection for edema, discussion of symptoms), adjusts antihypertensive dosing, and documents the encounter in the electronic health record. The clinician documents time, modality, patient location, and that the visit was delivered via telehealth for billing with M1426. Typical workflow steps include scheduling and consent, pre-visit data collection, synchronous video encounter, documentation of clinical decision-making and care plan, and electronic prescribing or patient instructions sent after the visit.
