Unsp inj intrns musc/fasc/tend finger at wrs/hnd lv, sequela

This code signifies a long-term complication or residual effect stemming from an unspecified injury to the small muscles, connective tissue, or tendons within a finger other than the thumb, occurring at the wrist or hand level. It indicates that the specific nature of the original injury is not documented, but its lasting impact is being addressed.

Use this code when documenting a sequela (e.g., chronic pain, stiffness, weakness, functional limitation) resulting from a past, unspecified injury to an intrinsic finger structure (excluding the thumb) at the wrist or hand. This applies when the acute phase of the original injury has passed, and the patient is presenting for treatment of the residual effects.

• Always assign a sequela code as a secondary diagnosis, following the code for the specific sequela itself (e.g., chronic pain, scar contracture).
• Ensure documentation clearly links the current condition to a previous, unspecified injury of an intrinsic finger structure at the wrist/hand level.
• Avoid using this code if the specific type of intrinsic muscle, fascia, or tendon injury is known and documented; in such cases, a more specific sequela code would be appropriate.
