simpleABI Exam Types
From a standard first-line ABI screen to a full treadmill stress protocol — every exam your practice needs for comprehensive PAD diagnosis, all in one system.
Reimbursable under Medicare CPT codes:
Single-level bilateral study. Standard ABI and ABI-Q exams.
Covers both multi-level segmental studies (3-cuff, 4-cuff, and toe combinations) and exercise ABI performed with functional maneuvers such as dorsiflexions, heel raises, or hall walking.
Treadmill stress protocol only. ABI Stress-Treadmill exam with documented walking time, claudication onset, and recovery curve.
ABI-Q Exam — PVR-Based PAD Diagnosis
When calcified arteries make standard ABI unreliable, ABI-Q reads pulse volume changes instead of relying on vessel compression. Accurate results for the patients most likely to be missed.
Single Level Exams
First-line PAD screening. Ankle pressures reflect any proximal or upstream occlusion — the most common entry point for vascular assessment. Billed under CPT 93922.
ABI Exam
CPT 93922Compares systolic pressures in arms and ankles. The standard first-line test for PAD. Completes in an average of 8 minutes including documentation.
View exam detailsABI with Toe Exam
CPT 93922Adds toe pressure (TBI) when ankle ABI is non-diagnostic. Essential when ankle arteries are calcified. TBI below 0.70 is diagnostic for PAD.
View exam detailsABI Seated Exam
CPT 93922Modified ABI protocol for patients who cannot lie supine. Adapted positioning for wheelchair-bound or mobility-limited patients.

Localizes the site of arterial occlusion. Pressure gradients greater than 20–30 mmHg between adjacent cuff levels identify the affected vascular segment. Billed under CPT 93923.
3-Cuff Segmental Exam
CPT 93923Thigh, calf, and ankle cuff levels localize occlusion to the aortoiliac, femoral, or tibial segment. Essential for pre-intervention planning.
View exam details3-Cuff with Toe Exam
CPT 93923Combines 3-level segmental localization with toe pressure for distal small vessel assessment. Preferred for diabetic multi-level disease.
View exam details4-Cuff Segmental Exam
CPT 93923Adds high-thigh cuff for maximum localization precision — differentiating aortoiliac from femoral-popliteal disease. Vascular lab standard.
View exam details4-Cuff with Toe Exam
CPT 93923The most comprehensive lower extremity arterial study — full segmental mapping plus distal toe pressures. Critical limb ischemia and pre-amputation assessment.
View exam detailsExercise & Stress Exams
Detects PAD that a resting exam misses. Over 30% of patients with a normal resting ABI will show signs of PAD with exercise. Exercise ABI with functional maneuvers (heel raises, dorsiflexions, hall walking) bills under CPT 93923. Treadmill stress protocols bill under CPT 93924.
ABI with Exercise Exam
CPT 93923Post-exercise pressure drop of 15–20% or more confirms PAD when resting ABI is normal. Uses functional maneuvers — no treadmill required. Billed under CPT 93923.

CPT 93924Structured treadmill protocol quantifies PAD severity — maximum walking time, claudication onset, and pressure recovery curve all documented.
