    CPT 99091: Interpretation of Patient-Provided Digital Health Data, 30 Minutes

    Medicare pays $57 on average nationally for this procedure.

    CPT code 99091 describes the interpretation and clinical analysis of patient-generated digital health data — for example, ECG tracings, blood pressure logs, or home glucose monitoring results — when the physician or other qualified healthcare professional spends at least 30 minutes in a 30-day period reviewing and interpreting that information; this service is remote data interpretation typically billed for clinical monitoring/management and is most often provided in outpatient or ambulatory settings where clinicians review electronic transmissions or portal-submitted records.

    Clinical & Coding Specifications

    Clinical Context

    A 68-year-old patient with known atrial fibrillation and hypertension transmits ambulatory single-lead ECG strips and multiple home blood pressure readings via a secure patient portal over a 30-day period. The physician or qualified healthcare professional reviews the digital data, aggregates trends, interprets rhythm and blood pressure excursions, and documents clinical findings and medical decision making. The review requires at least 30 minutes of the provider’s time within the 30-day reporting period and results in adjustments to anticoagulation counseling and antihypertensive medication. Typical workflow includes data receipt from a patient device or caregiver, secure retrieval of files, review and interpretation, documentation in the medical record, and communication of findings to the patient or care team. Typical site of service is outpatient ambulatory care or remote/telehealth service performed from the clinician’s office or other clinical workspace.
