ICD-10 Code M00.23 – Other streptococcal arthritis, wrist (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.23 – Other streptococcal arthritis, wrist
What it is
M00.23 identifies a streptococcal infection causing arthritis in the wrist joint. Use it when the record specifies the wrist and a streptococcal organism other than the listed streptococcal categories.
Clinical signs
Typical findings include a painful, swollen, warm wrist with reduced range of motion. Clinical features vary; refer to documentation for the organism and whether the arthritis is acute or confirmed by aspiration.
When to use this code
Use this code when the provider documents streptococcal septic arthritis affecting the wrist and does not assign a more specific streptococcal code. It also fits when notes clearly identify the wrist joint and an “other streptococcal” cause. Check documentation if laterality or organism details are unclear.
Do not use for
Do not use it for noninfectious arthritis, gout, or arthritis due to another organism. If the wrist infection is documented without streptococcal identification, check documentation for a more accurate code.
Coding tip
Verify both the joint site and the streptococcal etiology before assigning M00.23.
