Other specified arthritis, unspecified hand

This code signifies a form of arthritis affecting the hand that doesn't fit into more specific categories of inflammatory or degenerative joint disease. It indicates the presence of joint inflammation, pain, and/or stiffness in the hand, but the precise type of arthritis or its specific location within the hand is not fully documented or classified elsewhere.

Use this code when the medical record clearly documents "other specified arthritis" of the hand, but lacks further detail regarding the specific joint (e.g., carpometacarpal, metacarpophalangeal, interphalangeal) or the precise etiology (e.g., psoriatic, enteropathic, reactive). This code is appropriate when the provider has diagnosed arthritis of the hand but has not specified the exact type or location beyond "hand."

• Avoid using this code if a more specific ICD-10-CM code for arthritis of the hand is available and supported by documentation.
• Query the provider for greater specificity regarding the type and location of arthritis if possible, to allow for more precise coding.
• This code is for an unspecified hand; if the documentation specifies left or right hand, a more specific code (M13.841 or M13.842) should be used.
