ICD-10 Code L03.041 – Acute lymphangitis of right toe (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L03.041 – Acute lymphangitis of right toe
What it is
This code identifies an acute infection and inflammation of the lymphatic vessels in the right toe. It usually reflects a bacterial process spreading from a nearby skin break or wound.
Clinical signs
Common findings include localized redness, tenderness, swelling, and linear streaking that may extend from the toe. Clinical features vary; refer to documentation if the source and extent are not clearly stated.
When to use this code
Use L03.041 when the record specifically documents acute lymphangitis limited to the right toe. You may also use it when the clinician describes lymphatic infection of that toe with no broader site documented. Check documentation if cellulitis, abscess, or a different toe is mentioned.
Do not use for
Do not use this code for chronic lymphangitis, noninfectious inflammation, or unspecified foot infection. Also avoid it when the affected side or toe is not documented.
Coding tip
Verify laterality and anatomic site exactly; right toe must be documented to support L03.041.
