ICD-10 Code L03.314 – Cellulitis of groin (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L03.314 – Cellulitis of groin
What it is
L03.314 identifies cellulitis affecting the groin region. Use it for a localized bacterial skin and soft tissue infection in that area when the documentation supports the site.
Clinical signs
Typical findings include redness, warmth, swelling, and tenderness of the groin skin. Clinical features vary; refer to documentation for extent, laterality, and any associated abscess or drainage.
When to use this code
Use this code when the provider documents cellulitis specifically in the groin or inguinal area. It is appropriate for encounters describing an acute skin infection limited to that site, even if the cause is not named.
If the note mentions spread to nearby structures, multiple sites, or a different primary diagnosis, check documentation before coding. Code the documented location rather than a broader skin infection code when the groin is clearly identified.
Do not use for
Do not use it for abscess, furuncle, or other non-cellulitis infections unless the record states cellulitis. Do not assign it when the groin finding is only a symptom or the diagnosis is unclear; check documentation.
Coding tip
Confirm that the provider names the groin as the infected site, and code any additional documented organism or complication separately only when supported.
