ICD-10 Code M00.272 – Other streptococcal arthritis, left ankle and foot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.272 – Other streptococcal arthritis, left ankle and foot
What it is
This code identifies a streptococcal infection causing arthritis in the left ankle and foot. Use it when documentation specifies the joint involvement and indicates a streptococcal cause other than the standard categories.
Clinical signs
Typical findings include a painful, swollen, warm joint with reduced range of motion. Clinical features vary; refer to documentation for evidence of streptococcal infection and the affected left ankle or foot joint.
When to use this code
Use M00.272 when the provider documents other streptococcal arthritis affecting the left ankle and foot. This is appropriate for confirmed infectious arthritis with a streptococcal organism and clear laterality. Check documentation if the organism is not specified or if more than one joint is involved.
Do not use for
Do not use this code for noninfectious arthritis, septic arthritis due to a different organism, or unspecified joint location. If the record does not confirm streptococcal involvement, check documentation.
Coding tip
Verify both the organism and the exact left-sided joint site before assigning M00.272.
