Lacerat intrns musc/fasc/tend r thm at wrs/hnd lv, sequela

This code signifies a chronic or late-stage complication resulting from a laceration to the intrinsic muscles, fascia, or tendons of the right thumb, specifically within the wrist and hand region. It indicates that the initial injury has healed, but the patient is now experiencing residual effects such as pain, stiffness, weakness, or functional impairment directly attributable to the prior laceration.

Apply this code when documenting follow-up care for a patient who previously sustained a laceration to the intrinsic structures of their right thumb and is now presenting with persistent symptoms or long-term consequences of that injury. This is appropriate for conditions like chronic scar tissue formation, nerve entrapment due to scarring, or persistent functional deficits after the acute healing phase has passed.

• Ensure documentation clearly links the current symptoms to a previously sustained laceration of the right thumb's intrinsic structures.
• This "S" seventh character indicates a sequela, meaning the patient is being seen for the late effects or complications of the original injury.
• Do not use this code for the initial treatment of an acute laceration; use an acute injury code for that scenario.
