CPT Code 90805: Noninvasive Vascular Diagnostic Studies

CPT 90805 (Category III / Legacy): Noninvasive vascular study or procedure (e.g., photoplethysmography, ultrasonography, impedance plethysmography, oscillometry, volumetry, segmental pressures).

Important Clarification

As of current CPT editions, 90805 is no longer an active code for vascular studies. It was historically used but has been replaced by more specific codes in the 93922–93990 range (Duplex scans, physiologic studies). Always verify against the current year's CPT manual.

Current Noninvasive Vascular Study Codes (Examples)

• 93922: Limited bilateral physiologic study (e.g., segmental pressures, PVR).
• 93923: Complete bilateral physiologic study.
• 93925: Duplex scan of lower extremity arteries (unilateral/bilateral).
• 93926: Duplex scan of lower extremity veins (unilateral/bilateral).
• 93930: Duplex scan of upper extremity arteries/veins.
• 93970: Duplex scan of extracranial cerebrovascular arteries.
• 93975: Duplex scan of visceral/renal arteries.
• 93978: Duplex scan of aorta/IVC/iliacs.

Clinical Indications

• Peripheral arterial disease (claudication, rest pain, ulcers).
• Deep vein thrombosis (DVT) rule-out.
• Carotid stenosis screening (bruit, TIA, stroke).
• Aneurysm surveillance (AAA, popliteal).
• Vein mapping for bypass/conduit.
• Raynaud's, thoracic outlet syndrome.

Documentation Essentials

• Indication and clinical question.
• Vessels examined and laterality.
• Technique (Doppler, color flow, spectral analysis).
• Findings: velocities, waveforms, diameters, compressibility.
• Interpretation and impression.
