ICD-10 Code L89.4 – Pressure ulcer of contiguous site of back, buttock and hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.4 – Pressure ulcer of contiguous site of back, buttock and hip
What it is
L89.4 identifies a pressure ulcer affecting a contiguous area that includes the back, buttock, and hip. Use it when documentation shows one ulcer spanning these nearby sites rather than separate, distinct ulcers.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include localized skin breakdown over a pressure-prone area, with possible redness, open ulceration, drainage, or tissue loss consistent with pressure injury.
When to use this code
Use this code when the record clearly states a pressure ulcer of the contiguous back, buttock, and hip region. It is appropriate when the provider describes one lesion involving these adjacent areas, or when the site is documented exactly this way.
Do not infer this code from general immobility or sacral ulcers alone. Check documentation for the precise anatomic location and whether the ulcer is described as one contiguous site.
Do not use for
Do not use L89.4 for ulcers limited to only the back, only the buttock, or only the hip. If the site is unspecified or described differently, check documentation before coding.
Coding tip
Match the code to the exact wording in the chart; if the ulcer is not explicitly documented as contiguous across these sites, verify the location first.
