ICD-10 Code L89.621 – Pressure ulcer of left heel, stage 1 (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L89.621 – Pressure ulcer of left heel, stage 1
What it is
This code identifies a pressure ulcer on the left heel that is limited to intact skin with non-blanchable redness. It indicates early tissue damage from sustained pressure over a bony prominence.
Clinical signs
Typical findings include localized redness, warmth, or discoloration over the left heel that does not blanch when pressed. The skin remains intact, and clinical features vary; refer to documentation.
When to use this code
Use L89.621 when the record clearly documents a stage 1 pressure ulcer on the left heel. You should confirm the site, laterality, and stage in the provider note or wound assessment. If the documentation is incomplete, check documentation before assigning the code.
Do not use for
Do not use this code for pressure injuries at another heel, another body site, or a different stage. It is also not appropriate for non-pressure skin redness or wounds without documented pressure-related injury.
Coding tip
Always verify laterality and stage together, because heel pressure ulcers are coded by both details.
