Unsp inj flxr musc/fasc/tend l lit fngr at wrs/hnd lv, sqla

This code signifies the long-term effects or complications arising from an unspecified injury to the flexor muscle, fascia, and tendon of the left little finger. The injury occurred at the wrist or hand level, and the patient is now presenting with residual symptoms or conditions related to that past trauma.

Apply this code when documenting a patient's current condition that is a direct consequence of a previous, unspecified injury to the flexor structures of the left little finger. This is appropriate for follow-up visits where the initial acute injury has healed, but the patient experiences ongoing issues such as chronic pain, stiffness, weakness, or functional limitations attributable to the original trauma.

• Requires a seventh character "S" to indicate sequela, meaning the current condition is a late effect of the original injury.
• Ensure documentation clearly links the current symptoms to a past injury of the specified flexor structures.
• Do not use for acute injuries; instead, select an appropriate acute injury code from the S66.10- range.
