ICD-10 Code L89.42 – Pressure ulcer of contiguous site of back, buttock and hip, stage 2 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.42 – Pressure ulcer of contiguous site of back, buttock and hip, stage 2
What it is
This code identifies a stage 2 pressure ulcer affecting the contiguous area of the back, buttock, and hip. It indicates partial-thickness skin loss with exposed dermis in that combined anatomic region.
Clinical signs
Look for shallow open ulceration or an intact or ruptured blister in the affected area. The wound may appear pink or red and is not limited to deeper tissue loss; clinical features vary, so refer to documentation.
When to use this code
Use L89.42 when the record clearly documents a stage 2 pressure injury involving the contiguous back, buttock, and hip site. This is appropriate when the provider specifies both the stage and the combined location. Check documentation if the site is described separately or the stage is unclear.
Do not use for
Do not use this code for stage 1, stage 3, stage 4, or unstageable pressure ulcers. It is also wrong for ulcers at a different anatomic site or when the documentation does not support the contiguous-site designation.
Coding tip
Code the exact stage and site as documented, and verify whether the ulcer is described as contiguous or at a single location.
