Non-prs chronic ulcer oth prt right foot with oth severity

This code signifies a persistent, open sore on the right foot, excluding those caused by pressure. The ulcer involves a location other than the heel or midfoot, and its severity is specifically documented as something other than unspecified, minor, or with necrosis of muscle/bone. This condition typically arises from underlying vascular insufficiency, neuropathy, or trauma.

Apply this code when documentation clearly indicates a chronic, non-pressure ulcer on the right foot, located in an area such as the toes, forefoot, or ankle, and the severity is precisely described (e.g., with granulation tissue, deep tissue involvement without muscle/bone necrosis). This code is appropriate when the physician's notes specify the ulcer's depth or tissue involvement beyond a superficial level, but not extending to muscle or bone death.

• Always code the underlying cause of the ulcer (e.g., E11.621 for diabetic foot ulcer) first, followed by this code.
• Ensure the documentation specifies "right foot" and a location other than the heel or midfoot.
• Distinguish carefully between specified severity (e.g., with fat layer exposure) and unspecified severity (L97.519) or necrosis of muscle/bone (L97.513, L97.514).
