ICD-10 Code M00.231 – Other streptococcal arthritis, right wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.231 – Other streptococcal arthritis, right wrist
What it is
This code identifies a streptococcal infection causing arthritis in the right wrist. Use it when documentation specifies the organism as streptococcus and the affected joint as the right wrist.
Clinical signs
Typical findings include a painful, swollen, warm wrist with limited range of motion. Clinical features vary; refer to documentation for the organism, laterality, and whether the arthritis is acute or infectious.
When to use this code
Use M00.231 when the provider documents septic or infectious arthritis of the right wrist due to streptococcal infection. It also fits when the record names a streptococcal species but does not specify a more exact code. Confirm the right-sided joint and avoid guessing the organism.
Do not use for
Do not use this code for noninfectious arthritis, such as rheumatoid or osteoarthritis. Do not use it if the joint is not the right wrist or if the documentation does not support streptococcal causation.
Coding tip
Verify both the organism and laterality in the note before assigning M00.231.
