About Doppler Flow Testing
CPT code 93990 refers to doppler flow testing (billing description: "Doppler flow testing"). Under the 2026 Medicare Physician Fee Schedule, it is reimbursed at $144 in a facility (hospital or surgery center) and $144 in a doctor's office.
The Medicare rate is the closest thing to an objective "what this work is actually worth." A fair cash price for the uninsured is generally 1.5–3x that rate. Hospital sticker (gross) charges are often far higher — but almost nobody actually pays them.
