Coding Guidelines
The HCPCS/CPT code(s) may be subject to Correct Coding Initiative (CCI) edits. This information does not take precedence over CCI edits. Please refer to CCI for correct coding guidelines and specific applicable code combinations prior to billing Medicare.
When billing these procedures after a carotid endarterectomy, provide in the narrative the date of the surgery and the verbiage "carotid endarterectomy."
Do not report procedure codes 93890-93893 in conjunction with code 93888.
All non-invasive vascular study CPT codes are considered bilateral codes unless otherwise indicated in the CPT definition. The 150% payment adjustment for bilateral procedures does not apply. Modifier -50 and/or the anatomic modifiers, -LT/-RT should not be used.
Append the modifier –52 to report a unilateral study as appropriate. Information explaining the reduced service should be included in Item 19 of the CMS-1500 form or the electronic equivalent. Any appropriate documentation may be submitted with the claim to support the reduced service.
