ICD-10 Code L89.106 – Pressure-induced deep tissue damage of unspecified part of back (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.106 – Pressure-induced deep tissue damage of unspecified part of back
What it is
This code identifies a pressure injury with deep tissue damage on an unspecified area of the back. It is used when the record confirms back involvement but does not specify the exact site.
Clinical signs
Deep tissue pressure injury may present as persistent discoloration, a dark or purple area, or a blood-filled blister over pressure-prone skin. Clinical features vary; refer to documentation.
When to use this code
Use L89.106 when the provider documents pressure-induced deep tissue damage of the back and does not name a more precise back location. You should code it from clear documentation of pressure injury etiology and depth. If the record later specifies the exact back site, use the more specific code instead.
Do not use for
Do not use this code for non-pressure wounds, abrasions, or skin tears. It is also not appropriate when the documentation identifies a different back site or another ulcer stage.
Coding tip
Check whether the note says “deep tissue damage” and confirms pressure as the cause before assigning this code.
