ICD-10 Code M00.28 – Other streptococcal arthritis, vertebrae (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.28 – Other streptococcal arthritis, vertebrae
What it is
M00.28 identifies septic arthritis of the vertebral joints caused by streptococcal infection, other specified type. Use it when the record documents streptococcal involvement of the spine and no more specific code applies.
Clinical signs
Typical findings include localized spinal pain, tenderness, and reduced motion, with signs of joint infection. Clinical features vary; refer to documentation for confirmed organism and vertebral joint involvement.
When to use this code
Use this code when the provider documents streptococcal arthritis affecting vertebrae or spinal joints. It is appropriate when the organism is streptococcal but not identified as a more specific streptococcal subtype in the record. You should confirm that the infection is in the vertebral joint, not another spinal structure.
Do not use for
Do not use this code for non-streptococcal septic arthritis or for vertebral osteomyelitis without joint involvement. Check documentation if the site is unclear or if another organism is named.
Coding tip
Code the organism and anatomic site exactly as documented, and verify that “vertebrae” refers to joint infection rather than bone infection.
