ICD-10 Code M00.841 – Arthritis due to other bacteria, right hand (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M00.841 – Arthritis due to other bacteria, right hand
What it is
M00.841 identifies bacterial arthritis affecting the right hand. Use it when the record specifies a non-streptococcal, non-gonococcal bacterial cause and the right hand as the site.
Clinical signs
Typical findings include a painful, swollen, warm joint with reduced motion and tenderness. Clinical features vary; refer to documentation, especially for the confirmed organism and involved hand joint.
When to use this code
Use this code when the provider documents septic arthritis or infectious arthritis of the right hand caused by other bacteria. It also fits when the organism is identified in the note and the site is clearly the right hand.
If the chart only says arthritis without an infectious cause, do not assign this code. You should also confirm laterality and whether the infection is bacterial rather than fungal, viral, or gout-related.
Do not use for
Do not use M00.841 for unspecified arthritis, noninfectious inflammatory arthritis, or arthritis in another hand. Check documentation if the organism or right-sided location is not stated.
Coding tip
Verify both the bacterial etiology and the right-hand site before coding; missing either detail may require a different or unspecified code.
