ICD-10 Code M01.X72 – Direct infection of left ankle and foot in infectious and parasitic diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M01.X72 – Direct infection of left ankle and foot in infectious and parasitic diseases classified elsewhere
What it is
This code identifies a direct infection involving the left ankle or foot that occurs as part of another infectious or parasitic disease. Use it when the joint or nearby structures are infected and the underlying condition is documented elsewhere.
Clinical signs
Typical findings include localized pain, swelling, warmth, and limited motion in the left ankle or foot. Clinical features vary; refer to documentation for the causative infection and the affected site.
When to use this code
Use this code when the record clearly states direct infection of the left ankle or foot and links it to an infectious or parasitic disease classified elsewhere. You should code the underlying disease first when documentation supports it. If laterality or site is unclear, check documentation.
Do not use for
Do not use this code for trauma, degenerative joint disease, or nonspecific foot pain. It is also wrong when the infection is not documented as involving the left ankle or foot.
Coding tip
Confirm both the anatomic site and the underlying infection before assigning M01.X72.
