Stiffness of unspecified hand, not elsewhere classified

This code signifies a subjective complaint of restricted movement or inflexibility in a hand, where the specific cause or underlying pathology is not yet determined or documented. It describes a symptom rather than a definitive diagnosis of a specific hand disorder.

Use this code when documentation indicates "hand stiffness" without further specification of the affected hand (left or right) or the underlying etiology. This is appropriate for initial encounters or when the physician has not yet identified the specific joint or condition causing the stiffness.

• Avoid using this code if the laterality (left or right hand) is documented; instead, use the more specific M25.641 or M25.642.
• This code should generally be considered a temporary or primary symptom code until a more definitive diagnosis for the stiffness is established.
• Look for documentation of "unspecified hand stiffness," "hand feels stiff," or "restricted hand movement" without an identified cause.
