ICD-10 Code M00.232 – Other streptococcal arthritis, left wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.232 – Other streptococcal arthritis, left wrist
What it is
M00.232 identifies a streptococcal infection causing arthritis in the left wrist. Use it when documentation specifies the organism as streptococcal and the affected joint as the left wrist.
Clinical signs
Typical findings include a painful, swollen, warm wrist with limited motion and signs of joint inflammation. Clinical features vary; refer to documentation for confirmation of streptococcal involvement and laterality.
When to use this code
Use this code when the provider documents septic or infectious arthritis of the left wrist due to a streptococcal species other than a more specific category. It is appropriate when the record clearly links the infection to the joint and specifies the left wrist. If the organism or site is not documented, check documentation before coding.
Do not use for
Do not use this code for noninfectious arthritis, unspecified joint infection, or arthritis caused by a different organism. Check documentation if the record does not clearly identify streptococcal etiology or left-sided wrist involvement.
Coding tip
Verify both the causative organism and the exact joint laterality before assigning M00.232.
