ICD-10 Code M00.241 – Other streptococcal arthritis, right hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.241 – Other streptococcal arthritis, right hand
What it is
This code identifies a streptococcal infection causing arthritis in the right hand. Use it when the record specifies the right hand and the organism is streptococcal, but not a more specific streptococcal type.
Clinical signs
Findings typically include a painful, swollen, warm, and tender right-hand joint with reduced motion. Clinical features vary; refer to documentation for evidence of infection and the affected joint.
When to use this code
Use M00.241 when the provider documents septic or infectious arthritis of the right hand due to streptococcal infection. It is appropriate when the site is the right hand and the documentation does not name a different organism-specific code. Check documentation if the record only says arthritis, joint pain, or hand infection without confirming streptococcal cause.
Do not use for
Do not use this code for noninfectious arthritis, gout, or arthritis caused by another organism. Do not use it when the documentation does not confirm the right hand or does not identify streptococcal infection.
Coding tip
Verify both the organism and laterality in the note before assigning M00.241.
