Unsp inj intrinsic musc/fasc/tend finger at wrs/hnd lv, init

This code signifies an undiagnosed injury to the small muscles, connective tissue, or tendons located within a finger, excluding the thumb, at the level of the wrist or hand. The specific nature of the injury (e.g., sprain, strain, tear) has not yet been determined.

Use this code for initial encounters when a patient presents with pain, swelling, or dysfunction in a finger (other than the thumb) due to an injury, and the physician has not yet specified the exact type of intrinsic muscle, fascia, or tendon damage. This is appropriate when diagnostic workup is ongoing or pending.

• Ensure the documentation clearly indicates an injury to an intrinsic structure of a finger (not the thumb) at the hand/wrist level.
• Only use this code for the initial encounter for the injury.
• Avoid using this code if a more specific diagnosis (e.g., sprain, strain, tear) is documented.
