Inj long flexor musc/fasc/tend r thm at wrs/hnd lv, sequela

This code signifies a long-term complication or residual effect stemming from a previous injury to the long flexor muscle, fascia, or tendon of the right thumb, specifically located at the wrist or hand level. This could include issues like chronic pain, stiffness, limited range of motion, or weakness that persists after the initial healing phase of the original injury.

Use this code when documenting a patient presenting with ongoing problems directly attributable to a past injury of the specified right thumb flexor structures. This is appropriate for follow-up encounters addressing the chronic sequelae, not the initial acute injury. It should be used when the acute phase of the original injury has passed and the patient is experiencing residual symptoms.

• Always assign this code as a secondary diagnosis, with the primary diagnosis reflecting the specific nature of the sequela (e.g., chronic pain, contracture).
• Ensure documentation clearly links the current condition to a previous injury of the right thumb's long flexor structures at the wrist/hand.
• Do not use this code for acute injuries; refer to the appropriate initial encounter or subsequent encounter codes for active treatment of the original injury.
