Summary & Overview
CPT 93151: Phrenic Nerve Stimulation Interrogation and Programming
CPT code 93151 covers interrogation and programming of a phrenic nerve stimulation system, including assessment of device function and adjustment of at least one parameter. This code is used when a trained clinician evaluates an implanted phrenic nerve stimulator and modifies settings to maintain or improve diaphragmatic pacing and respiratory support. Nationally, proper coding for implanted device management is important for accurate billing and device follow-up care coordination.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of where CPT code 93151 fits clinically, expected sites of service, common documentation elements, and payer considerations. The publication summarizes common modifiers used with device interrogation services, highlights clinical context for phrenic nerve stimulation follow-up, and outlines typical billing scenarios for outpatient device management.
This report is intended for clinicians, billing professionals, and policy analysts seeking concise guidance on coding and operational implications of device interrogation and programming for phrenic nerve stimulators. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 93151 describes interrogation and programming of a phrenic nerve stimulation system, with adjustment of at least one parameter. This service involves a clinician assessing the implanted stimulator, reviewing device performance and settings, and making programming changes as needed to optimize therapy.

Clinical & Coding Specifications
Clinical Context
A 62-year-old male with a phrenic nerve stimulation implant for central sleep apnea presents to the cardiac device clinic for routine device interrogation and programming. The visit is scheduled as an outpatient clinic encounter in a cardiology or electrophysiology clinic. The clinician reviews the device log, assesses lead impedance and pacing thresholds, evaluates therapy delivery history, and confirms battery status. If parameters require adjustment, the provider performs programming changes to stimulation amplitude, pulse width, or timing to optimize diaphragmatic capture and patient symptom control. Documentation includes device model and serial number, baseline and post-programming parameter values, patient tolerance, and any adverse events. The procedure typically takes 15–45 minutes and may be billed to commercial payors such as Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, or to Medicare, using CPT code 93151 for phrenic nerve stimulation system interrogation and programming for at least one parameter.
