ICD-10 Code M00.222 – Other streptococcal arthritis, left elbow (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.222 – Other streptococcal arthritis, left elbow
What it is
This code identifies a streptococcal infection involving the left elbow joint. Use it when the provider documents septic arthritis caused by a streptococcal organism, but not a more specific streptococcal type.
Clinical signs
Typical findings include a painful, swollen, warm, and tender elbow with reduced range of motion. Clinical features vary; refer to documentation for the organism and laterality.
When to use this code
Use M00.222 when the record clearly states other streptococcal arthritis affecting the left elbow. It fits confirmed joint infection documented as streptococcal and limited to the left elbow. If the organism or site is unclear, check documentation before coding.
Do not use for
Do not use this code for noninfectious arthritis, unspecified septic arthritis, or streptococcal infection in another joint. Do not assume left-sided involvement unless it is documented.
Coding tip
Verify both the streptococcal cause and left elbow laterality in the provider note before assigning M00.222.
