ICD-10 Code A02.23 – Salmonella arthritis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A02.23 – Salmonella arthritis
What it is
A02.23 identifies arthritis caused by Salmonella infection. Use it when the joint inflammation is documented as due to Salmonella rather than another bacterial or inflammatory cause.
Clinical signs
Patients may have joint pain, swelling, warmth, and limited motion, often with a recent or concurrent Salmonella infection. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents Salmonella as the cause of the arthritis, including septic or infectious joint involvement linked to that organism. It may be supported by culture results, clinical assessment, or clear charted attribution. If the record only says “infectious arthritis,” check documentation before assigning A02.23.
Do not use for
Do not use this code for arthritis from other bacteria, viral causes, reactive arthritis, or nonspecific joint pain. Check documentation if Salmonella is not clearly identified.
Coding tip
Verify that Salmonella is explicitly documented as the cause of the joint infection before coding A02.23.
