ICD-10 Code L03.316 – Cellulitis of umbilicus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L03.316 – Cellulitis of umbilicus
What it is
Cellulitis of the umbilicus is a localized bacterial infection of the skin and soft tissue around the navel. Use this code when documentation specifically identifies umbilical cellulitis.
Clinical signs
Typical findings include redness, warmth, swelling, tenderness, and possible drainage around the umbilicus. Clinical features vary; refer to documentation.
When to use this code
Use L03.316 when the provider documents cellulitis limited to the umbilical area, whether acute or unspecified in timing. It is appropriate when the record supports a skin and soft tissue infection of the navel and does not identify a deeper or different abdominal wall process.
Do not use for
Do not use this code for simple irritation, omphalitis without cellulitis documentation, or generalized abdominal wall infection. Check documentation if the note describes abscess, postoperative infection, or a different site.
Coding tip
Code from the provider’s exact anatomic wording; “umbilicus” is more specific than generic abdominal wall cellulitis.
