Lacerat long flexor musc/fasc/tend l thm at wrs/hnd lv, sqla

This code signifies a long-term complication or residual effect stemming from a previous laceration to the long flexor muscle, its surrounding fascia, and the associated tendon of the left thumb. This injury specifically occurred at the wrist or hand level. The sequela indicates that the acute injury has healed, but there are ongoing issues directly attributable to that past laceration.

Use this code when documenting a patient presenting with chronic pain, limited range of motion, weakness, or other persistent functional deficits in the left thumb, wrist, or hand that are directly linked to a previously sustained laceration of the long flexor muscle/tendon complex. This code is appropriate for follow-up visits addressing these long-term consequences, not the initial acute injury.

• Always sequence the sequela code first, followed by codes for the specific manifestations of the sequela (e.g., chronic pain, contracture).
• Ensure documentation clearly links the current condition to a past laceration of the specified muscle/tendon.
• Do not use this code for acute lacerations; refer to the acute injury codes in the S66.02 category for initial encounters.
