Unsp inj intrns musc/fasc/tend r lit fngr at wrs/hnd lv,init

This code signifies an undiagnosed injury to the intrinsic muscles, fascia, or tendons within the right little finger, specifically at the wrist or hand level. The exact nature of the injury (e.g., strain, tear) is not yet determined. This code is for the initial treatment or evaluation of the injury.

Use this code when a patient presents with pain, swelling, or functional impairment of the right little finger at the hand/wrist level, and diagnostic imaging or a thorough clinical examination has not yet specified the exact intrinsic muscle, fascia, or tendon involved, or the precise type of injury. It is appropriate for the initial encounter where further investigation is planned or underway.

• Only use for the right little finger; specific codes exist for other digits and sides.
• "Unspecified" indicates the precise nature of the injury is unknown; avoid if a more specific diagnosis is documented.
• The "A" suffix denotes an initial encounter for active treatment of the injury.
