HCPCS G0365 is officially defined as "Vessel mapping of vessels for hemodialysis access (services for preoperative vessel mapping prior to creation of hemodialysis access using an autogenous hemodialysis conduit, including arterial inflow and venous outflow)." HCPCS G0365 is referenced in 2 tracked payer policy changes from Medicare/CMS - LCD and Indiana Medicaid (IHCP). For billers and coders, staying current on payer-specific coverage criteria, reimbursement rules, and prior-authorization requirements for HCPCS G0365 is critical to clean claim submission. Each entry below links to the full policy analysis with effective dates and action steps.
CGS's LCD L34045 (Non-Invasive Vascular Studies), revised with an effective date of 11/5/2026, expands coverage to include arterial fibromuscular dysplasia (FMD) for non-invasive vascular studies, based on new literature and societal input supporting non-invasive testing for this condition. The revision is described as a coverage expansion rather than a restriction, with all other existing indications and limitations carried over from the prior version.
The IHCP reviewed the Outpatient Fee Schedule, found discrepancies, and will reflect the changes in the next regular update to that schedule. Codes listed twice on previous versions will appear only once, codes missing from the schedule are covered in the outpatient setting and can be billed for dates of service on or after the date listed for each code, and other listed codes are noncovered and will be added to the schedule. Codes that have been nationally end dated will be removed from the schedule, and Current Dental Terminology (CDT) codes cannot be billed on institutional claims (UB-04 claim form or electronic equivalent).
