L97.426
Non-pressure chronic ulcer of left heel and midfoot with bone involvement without evidence of necrosis
Clinical Classification Guidelines
Medical Intelligence & Overview
A non-pressure chronic ulcer of the left heel and midfoot with bone involvement is a persistent wound that develops on the underside of the foot, specifically affecting the heel and midfoot region. This type of ulcer is characterized by its long duration and involvement of underlying bone structures without the presence of dead tissue (necrosis). It often results from conditions that impair healing or blood flow, leading to a slow-healing wound that can cause significant complications if not properly managed.
Causes & Symptoms
Clinical Causes: Diabetes mellitus leading to peripheral neuropathy and poor circulation Chronic venous insufficiency affecting foot tissues Repeated trauma or injury to the heel and midfoot areas Poor footwear or ill-fitting shoes contributing to persistent pressure Underlying vascular diseases reducing blood flow to the affected area Pressure from deformities or foot abnormalities (though these are non-pressure ulcers, deformities can still contribute indirectly)
Key Symptoms: Open sore or wound on the heel or midfoot that is slow to heal Swelling or redness around the ulcer Persistent pain or tenderness at the site Possible drainage or oozing from the wound Discolored or abnormal tissue near the ulcer In some cases, bone may become involved, leading to deeper infection or osteomyelitis
Diagnostic & Treatment
Diagnosis Path: Physical examination of the ulcer to assess size, depth, and signs of infection Imaging tests such as X-rays to evaluate bone involvement Laboratory tests to identify infection or underlying systemic issues Wound cultures to detect bacterial presence if infection is suspected Assessment of blood flow and nerve function (e.g., Doppler studies, monofilament testing)
Treatment Protocols: Offloading pressure from the ulcer to promote healing, often with specialized footwear or devices Regular wound care, including cleaning and dressing changes Debridement to remove non-viable tissue and encourage new tissue growth Management of underlying conditions such as diabetes or vascular disease Antibiotic therapy if infection is present Monitoring bone involvement and treating osteomyelitis if diagnosed Nutrition optimization to support wound healing In some cases, surgical intervention may be necessary to remove damaged tissue or bone
