Inj flexor musc/fasc/tend unsp finger at wrs/hnd lv, subs

This code signifies an injury to the flexor muscles, fascia, or tendons of an unspecified finger, occurring at the wrist or hand level. This injury is not a strain, sprain, or laceration, but rather another type of damage such as a rupture, tear, or crush, and is being treated during a subsequent encounter.

Use this code for follow-up care of a patient who previously sustained an injury to the flexor structures of an unspecified finger at the wrist or hand. This includes situations like post-operative care, follow-up for conservative management, or evaluation of healing progress after the initial treatment phase.

• Ensure the documentation specifies an "other" type of injury (e.g., rupture, tear) and not a strain, sprain, or open wound.
• Confirm the encounter is for subsequent care, not the initial treatment of the injury.
• If the specific finger is known, a more precise code from the S66.1- series should be used.
