ICD-10 Code M00.212 – Other streptococcal arthritis, left shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.212 – Other streptococcal arthritis, left shoulder
What it is
This code identifies septic arthritis of the left shoulder caused by streptococcal infection, when the organism is documented as streptococcal but not a more specific type. Use it for an infected joint, not for simple shoulder pain.
Clinical signs
Typical findings include a painful, swollen, warm shoulder with limited range of motion and joint effusion. Clinical features vary; refer to documentation for the confirmed streptococcal cause and left-sided joint involvement.
When to use this code
Use M00.212 when the record clearly documents streptococcal arthritis affecting the left shoulder. It is appropriate when the provider identifies septic arthritis or infectious arthritis of that joint and names streptococcus as the cause. Check documentation if the organism is not specified or if another joint is involved.
Do not use for
Do not use this code for degenerative, traumatic, or inflammatory arthritis without infection. Also avoid it when the organism is not streptococcal or when the affected site is not the left shoulder.
Coding tip
Verify both the organism and laterality in the note before assigning M00.212.
