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

This code signifies a persistent open sore on the neck that is not caused by pressure and has progressed to involve the underlying bone. The ulcer shows no signs of dead tissue. It indicates a deep, non-healing lesion affecting the skeletal structure of the neck.

Apply this code when documentation clearly states a chronic, non-pressure ulcer on the neck with confirmed bone involvement, such as osteomyelitis, but explicitly notes the absence of necrosis. This typically applies to advanced stages of non-pressure ulcers where infection or inflammation has eroded into the bone.

• Ensure documentation explicitly states "non-pressure" and "bone involvement" without "necrosis."
• Do not use for pressure ulcers; refer to the L89 series for those.
• Confirm the anatomical site is specifically the "neck" to differentiate from other body regions.
