Oth athscl native arteries of extremities, oth extremity

This code signifies atherosclerosis affecting native arteries in the extremities, specifically when the condition is not specified as intermittent claudication, rest pain, or ulceration. It indicates a generalized hardening and narrowing of the arteries due to plaque buildup, impacting blood flow to the limbs.

Use this code for documented atherosclerosis of the native arteries in the upper or lower extremities when the specific clinical manifestation (e.g., claudication, rest pain, ulceration, gangrene) is not detailed or is explicitly stated as "other." Documentation should clearly state "atherosclerosis of extremity arteries" without further specific clinical sequelae.

• Do not use this code if the documentation specifies intermittent claudication (I70.21-), rest pain (I70.22-), or ulceration (I70.23- to I70.26-).
• Ensure the documentation specifies "native arteries" to differentiate from bypass grafts.
• Always code the specific extremity (e.g., right, left, bilateral) if documented, using the appropriate 6th character.
