Reimbursement for CPT codes 93922, 93923 CPT or 93924 CPT when submitted with Duplex scan CPT codes 93925 or CPT 93926

Vascular studies include patient care required to perform the studies, supervision of the studies and interpretation of study results with copies for patient records of hard copy output with analysis of all data, including bi-directional vascular flow or imaging when provided.


Noninvasive vascular procedures will not be covered when performed based on internal protocols of the testing facility; a referral for one non-invasive study is not a blanket referral for all studies. The provider treating the patient must specifically order the procedures in writing; an order must be on record for each non-invasive study performed.

When an uninterpretable study (i.e., poor quality or not in accordance with regulatory standards) results in performing another type of study, only the successful study should be billed.  For example, when an uninterpretable non-invasive physiologic study (CPT code 93922, 93923 CPT or 93924 CPT) is performed which results in performing a duplex scan (CPT codes 93925 or 93926 CPT ), only the duplex scan should be billed.

Performance of both a physiological test (CPT codes 93922, 93923 CPT, 93924 CPT ) and duplex scanning (CPT codes 93925, CPT 93926) of extremity arteries during the same encounter would not generally be expected. Consequently, documentation must clearly support the medical necessity if both procedures are performed during the same encounter, and be available to Medicare upon request.

Note: Reimbursement of physiologic testing will not be allowed after a duplex scan has been performed.

Since the signs and symptoms of arterial occlusive disease and venous disease are so divergent, the performance of simultaneous arterial and venous studies during the same encounter should be rare. Consequently, documentation must clearly support the medical necessity of both procedures if performed during the same encounter.

CPT codes 93922 and 93923 CPT are considered to be a part of CPT code 93924.

Reimbursement for  non-invasive extracranial arterial studies (CPT codes 93880 or 93881) when submitted with non-invasive evaluation of extremity arteries (CPT codes 93922, 93923 CPT , 93924)

Performance of both non-invasive extracranial arterial studies (CPT codes 93880 or 93881) and non-invasive evaluation of extremity arteries (CPT codes 93922, 93923 CPT, 93924) during the same encounter is not appropriate as a general practice or standing protocol, and therefore, would not generally be expected. Consequently, documentation must clearly support the medical necessity if both procedures are performed during the same encounter, and be available to Medicare upon request.
