ICD-10 Code L89.111 – Pressure ulcer of right upper back, stage 1 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.111 – Pressure ulcer of right upper back, stage 1
What it is
This code identifies a pressure injury on the right upper back with intact skin and persistent nonblanchable redness. It is used when the ulcer is limited to stage 1 severity.
Clinical signs
Look for localized erythema over the right upper back that does not blanch when pressed. The skin remains unbroken; if the area is open or deeper tissue is involved, check documentation.
When to use this code
Use L89.111 when the provider documents a stage 1 pressure ulcer specifically on the right upper back. The record should support the site and stage, and the lesion should be described as pressure-related. If laterality, location, or stage is unclear, check documentation.
Do not use for
Do not use this code for nonpressure skin redness, abrasions, or ulcers at another body site. It is also inappropriate if the wound is documented as stage 2, unstageable, or deep tissue injury.
Coding tip
Match the documented anatomic site and stage exactly, because pressure ulcer codes are highly specific.
