External Counterpulsation (ECP) Therapy - CPT G0166, 92971,93040,

Commonly referred to as enhanced external counterpulsation, is a non-invasive outpatient treatment for coronary artery disease refractory medical and/or surgical therapy. Effective for dates of service July 1, 1999, and after, Medicare will cover ECP when its use is in patients with stable angina (Class III or Class IV, Canadian Cardiovascular Society Classification or equivalent classification) who, in the opinion of a cardiologist or cardiothoracic surgeon, are not readily amenable to surgical intervention, such as PTCA or cardiac bypass, because:

• Their condition is inoperable, or at high risk of operative complications or post-operative failure;
• Their coronary anatomy is not readily amenable to such procedures; or
• They have co-morbid states that create excessive risk.

Billing and Payment Requirements

Effective for dates of service on or after January 1, 2000, use HCPCS code G0166 (External counterpulsation, per session) to report ECP services. The codes for external cardiac assist (92971), ECG rhythm strip and report (93040 or 93041), pulse oximetry (94760 or 94761) and plethysmography (93922 or 93923) or other monitoring tests for examining the effects of this treatment are not clinically necessary with this service and should not be paid on the same day, unless they occur in a clinical setting not connected with the delivery of the ECP. Daily evaluation and management service, e.g., 99201-99205, 99211-99215, 99217-99220, 99241-99245, cannot be billed with the ECP treatments. Any evaluation and management service must be justified with adequate documentation of the medical necessity of the visit. Deductible and coinsurance apply.
