ICD-10 Code M01.X41 – Direct infection of right hand in infectious and parasitic diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code M01.X41 – Direct infection of right hand in infectious and parasitic diseases classified elsewhere
What it is
M01.X41 identifies a direct infection involving the right hand that occurs in the setting of another infectious or parasitic disease classified elsewhere. Use it when the hand infection is secondary to, and linked with, a separate underlying condition.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include localized pain, swelling, warmth, redness, and reduced hand function, with evidence that the infection is directly related to the underlying infectious or parasitic process.
When to use this code
Use this code when the provider documents a direct infection of the right hand and identifies an associated infectious or parasitic disease elsewhere as the cause. You should code the underlying disease first when instructed by the record or coding guidelines. Do not use it for nonspecific hand pain or inflammation without documented infection.
Do not use for
Do not use this code for superficial skin infections, trauma-related hand wounds, or arthritis without infection. Check documentation if the record does not clearly link the right hand infection to another infectious or parasitic disease.
Coding tip
Confirm both laterality and the underlying infectious or parasitic condition before assigning M01.X41.
