ICD-10 Code M00.24 – Other streptococcal arthritis, hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.24 – Other streptococcal arthritis, hand
What it is
This code identifies a streptococcal infection causing arthritis in the hand joints. Use it when documentation specifies a streptococcal cause and the affected site is the hand.
Clinical signs
Typical findings include painful, swollen, warm, and limited-motion hand joints. Clinical features vary; refer to documentation for the confirmed streptococcal organism and joint involvement.
When to use this code
Use M00.24 when the provider documents septic or infectious arthritis of the hand due to streptococcal infection. It is appropriate when the hand is the involved site and the record supports a streptococcal etiology. Check documentation if the organism is not clearly stated.
Do not use for
Do not use this code for arthritis caused by organisms other than streptococci, or for noninfectious inflammatory arthritis. Do not assign it if the documentation does not identify the hand as the affected joint.
Coding tip
Confirm both the organism and the anatomic site in the note before coding.
