ICD-10 Code M00.071 – Staphylococcal arthritis, right ankle and foot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.071 – Staphylococcal arthritis, right ankle and foot
What it is
This code identifies an acute joint infection caused by Staphylococcus affecting the right ankle and foot. Use it when documentation specifies staphylococcal septic arthritis in that location.
Clinical signs
Typical findings include a painful, swollen, warm joint with reduced range of motion. Fever or systemic illness may occur; clinical features vary, so refer to documentation.
When to use this code
Use M00.071 when the provider documents staphylococcal arthritis, septic arthritis, or pyogenic arthritis due to Staphylococcus in the right ankle or foot. Apply it when the infection is clearly localized to that site. Check documentation if the organism or laterality is not stated.
Do not use for
Do not use this code for arthritis without an infectious cause, or for staphylococcal infection at another joint. If the record does not confirm the right ankle and foot, code the documented site instead.
Coding tip
Match the organism and laterality exactly; if either is missing, query the provider before assigning M00.071.
