ICD-10 Code L03.317 – Cellulitis of buttock (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L03.317 – Cellulitis of buttock
What it is
L03.317 identifies cellulitis involving the buttock, a bacterial skin and soft tissue infection. It is used when documentation specifies this anatomic site.
Clinical signs
Typical findings include localized redness, warmth, swelling, tenderness, and sometimes spreading skin inflammation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents cellulitis of the buttock or an infection clearly limited to that area. You may also use it when the note states right or left buttock cellulitis, if no more specific code is available.
If the record describes abscess, pressure injury, or another skin condition instead of cellulitis, do not assign L03.317. Check documentation for laterality, organism, or associated conditions only if they are clearly documented.
Do not use for
Do not use this code for generalized skin infection without buttock involvement, or for abscess without cellulitis. If the diagnosis is uncertain, check documentation.
Coding tip
Code only when the buttock site is explicitly documented; do not infer location from vague “skin infection” wording.
