Athscl native arteries of extrm w intrmt claud, oth extrm

This code signifies peripheral artery disease (PAD) affecting the native arteries of an extremity, excluding the lower limbs, where the primary symptom is intermittent claudication. It indicates atherosclerotic narrowing or hardening of the arteries in areas such as the upper extremities, leading to pain or cramping during exercise that is relieved by rest.

Apply this code when documentation specifies atherosclerosis of a native artery in an upper extremity or other non-lower limb extremity, and the patient experiences intermittent claudication. Supporting documentation should clearly state the affected extremity (e.g., right arm, left arm) and confirm the presence of claudication.

• Ensure the documentation specifies "other extremity" to differentiate from lower limb involvement.
• Do not use this code if the claudication is due to an embolism, thrombosis, or aneurysm.
• Verify the claudication is intermittent; persistent pain or rest pain would require a different code.
