The ankle-brachial pressure index (ABPI) or ankle-brachial index (ABI) is the ratio of the blood pressure at the ankle to the blood pressure in the upper arm (brachium). Compared to the arm, lower blood pressure in the leg suggests blocked arteries due to peripheral artery disease (PAD).
Ankle-brachial pressure index (ABPI) assesses peripheral vascular disease. It may however be unreliable in patients with calcified arteries in the calf (often diabetic patients) or those with extensive oedema , in which case toe pressure or Toe-brachial pressure index (TBPI) should be measured to aid in the diagnosis.
Ischemia is graded 0 through 3 based on ABI, ankle systolic pressure, and toe pressure. [66] Grade 0: ABI ≥0.80, ankle systolic pressure ≥100 mm Hg, toe pressure ≥60 mm Hg; Grade 1: arterial brachial index 0.6 to 0.79, ankle systolic pressure 70 to 100 mm Hg, toe pressure 40 to 59 mm Hg

The CPT code revisions in 2013 were part of a periodic five-year review of codes. Some psychotherapy codes changed numbers, for example 90806 changed to 90834 for individual psychotherapy of a similar duration. Add-on codes were created for the complexity of communication about procedures.

Vascular doctors and nurses may use special pads to ensure uniform higher pressure around the circumference of the ankle (to smooth out the irregular cross-sectional profile.) Self-prescription is reasonably safe assuming that the compression gradient is 15–20 mmHg, the ABPI (for both legs) is >1.0 and that the stockings fit correctly.
The ICD-10 Procedure Coding System (ICD-10-PCS) is a US system of medical classification used for procedural coding.The Centers for Medicare and Medicaid Services, the agency responsible for maintaining the inpatient procedure code set in the U.S., contracted with 3M Health Information Systems in 1995 to design and then develop a procedure classification system to replace Volume 3 of ICD-9-CM.
