ICD-10 Code L89.46 – Pressure-induced deep tissue damage of contiguous site of back, buttock and hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.46 – Pressure-induced deep tissue damage of contiguous site of back, buttock and hip
What it is
This code identifies pressure-induced deep tissue damage affecting a contiguous area across the back, buttock, and hip. It is used when the injury is documented as deep tissue damage rather than a superficial skin breakdown.
Clinical signs
Typical findings include persistent discoloration, localized pain, or a maroon, purple, or darkened area over pressure points. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents deep tissue damage involving the back, buttock, and hip as one contiguous site. It fits pressure-related injury descriptions that specify this exact combined location. If the note is unclear about depth or site, check documentation before assigning the code.
Do not use for
Do not use it for simple redness, abrasions, or unspecified pressure ulcers without deep tissue damage. Do not use it when the record names a different anatomic site or does not support pressure-induced injury.
Coding tip
Match both the pressure injury depth and the combined anatomic site exactly as documented.
