ICD-10 Code L03.327 – Acute lymphangitis of buttock (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L03.327 – Acute lymphangitis of buttock
What it is
L03.327 identifies acute lymphangitis affecting the buttock. It describes an acute inflammatory infection of lymphatic vessels in that specific location.
Clinical signs
Typical findings include localized redness, warmth, tenderness, and linear streaking that may extend from the infected area. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents acute lymphangitis of the buttock or clearly identifies lymphatic inflammation at that site. You should support the code with location-specific documentation in the note. If the record only states cellulitis or a nonspecific skin infection, check documentation before assigning L03.327.
Do not use for
Do not use this code for chronic lymphatic disorders, generalized lymphadenitis, or skin infections without documented lymphangitis. If the anatomic site is not the buttock, choose the code that matches the documented location.
Coding tip
Verify both the acute nature and the buttock location in the provider note before coding.
