ICD-10 Code M00.22 – Other streptococcal arthritis, elbow (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.22 – Other streptococcal arthritis, elbow
What it is
M00.22 identifies a streptococcal infection of the elbow joint causing septic arthritis. Use it when the provider documents other streptococcal arthritis affecting the elbow.
Clinical signs
Typical findings include a painful, swollen, warm elbow with reduced range of motion. Clinical features vary; refer to documentation for the specific streptococcal organism and joint involvement.
When to use this code
Use M00.22 when the record clearly states streptococcal septic arthritis of the elbow, especially if the organism is not one of the more specific streptococcal categories. You should code it from provider documentation, imaging, aspiration, or culture results that support the diagnosis. Check documentation if the organism or joint site is unclear.
Do not use for
Do not use this code for nonstreptococcal septic arthritis, traumatic joint injury, or nonspecific elbow pain. If the chart does not identify streptococcal infection, check documentation.
Coding tip
Confirm both the organism and the elbow site in the final diagnosis before assigning M00.22.
