Claims for stress tests performed as preoperative evaluation of asymptomatic, moderate-risk patients must include medical record documentation of at least one of: diabetes mellitus with complications; peripheral vascular disease; aortic aneurysm; or cerebrovascular disease.
This billing/coding guideline complements LCD L33459 (Computerized Axial Tomography (CT), Thorax); follow the LCD for clinical coverage and any required documentation or prior authorization rules.
When a limited or follow-up echocardiogram is performed, document the targeted cardiac problem/region and bill using the appropriate CPT code (93308 or 93321).
If the study is a screening exam, document and bill with the appropriate screening ICD-10 code; document any abnormal findings and use the resulting diagnosis for subsequent billing when applicable.

Preoperative cardiac stress testing with radionuclide imaging for asymptomatic patients deemed at moderate risk is covered only if the medical record documents at least one of the following: diabetes mellitus with complications; peripheral vascular disease; aortic aneurysm; or cerebrovascular disease.
Follow-up or limited transthoracic echocardiography performed to evaluate a single specified cardiac problem or region must be billed with CPT 93308.
Limited Doppler/follow-up echocardiographic studies (for targeted velocity or gradient assessment) should be billed with CPT 93321 (e.g., tricuspid regurgitant velocity to estimate pulmonary artery systolic pressure or sequential transmitral velocity in mitral stenosis).
Coverage and clinical indications for Cardiac Computed Tomography & Angiography (CCTA) follow the Local Coverage Determination LCD L33423; this billing article provides complementary coding guidance only.
Therapeutic procedures whose principal aim is to treat a respiratory impairment must be billed using HCPCS codes G0237, G0238, or G0239.
