Non-prs chr ulcer of back with bone invl without evd of necr

This code signifies a persistent, open sore on the patient's back that is not caused by pressure, and where the ulceration extends down to and affects the underlying bone. Importantly, there is no indication of dead tissue (necrosis) within the ulcer or surrounding area. This condition often arises from underlying vascular insufficiency, neuropathy, or trauma.

Apply this code when documentation clearly states a chronic, non-pressure ulcer located on the back, with direct involvement of the bone, and explicitly notes the absence of necrosis. This typically applies to ulcers that have been present for an extended period and have progressed to a deep tissue level. Supporting documentation would include physician notes detailing the ulcer's chronicity, location, depth, and confirmation of bone involvement through physical examination or imaging, along with a statement ruling out necrosis.

• Ensure documentation specifies "non-pressure" to differentiate from pressure ulcers.
• Verify the ulcer's location is explicitly "back" and that bone involvement is clearly stated.
• Confirm the absence of necrosis; if necrosis is present, a different code would be appropriate.
