Summary & Overview
HCPCS M1151: Heart Transplant Status or LVAD Support
HCPCS Level II code M1151 flags patients with a history of heart transplant or those supported by a left ventricular assist device (LVAD). Nationally, this designation matters because it identifies a high-acuity population that requires specialized follow-up, coordination across inpatient and outpatient settings, and distinct resource allocation for device management and transplant aftercare.
Key payers evaluated include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for M1151, typical sites of service, commonly associated billing modifiers, and the types of performance benchmarks and utilization metrics that payers commonly monitor for this population. The summary highlights how payers and providers classify and bill for care related to cardiac transplant and LVAD patients and what operational areas—such as care coordination, readmission risk, and device management—are most relevant.
This publication provides national-level guidance on interpretation of the code, the payers that commonly reimburse services for these patients, and the practical billing and administrative considerations tied to caring for individuals with heart transplants or LVADs.

Clinical & Coding Specifications
Clinical Context
A 58-year-old man with a prior orthotopic heart transplant who now presents for routine device supply and evaluation related to ambulatory care services for patients with complex cardiac history. The patient is seen in a cardiac transplant clinic or durable medical equipment (DME) distribution center by a cardiovascular advanced practice provider or DME coordinator. The clinical workflow includes verification of transplant history or presence of a left ventricular assist device (LVAD), assessment of current device needs, ordering and billing for specialized supplies or durable medical equipment under billing code M1151, documentation of transplant or LVAD status in the chart, insurance eligibility and prior authorization check, and coordination of home delivery and patient education. Typical sites of service include an outpatient cardiac transplant clinic, hospital-based outpatient DME distribution area, or home health setup when supplies are delivered to the patient’s residence.
