Unsp inj extn musc/fasc/tend r idx fngr at wrs/hnd lv, sqla

This code signifies a long-term complication or residual effect stemming from an unspecified injury to the extensor muscle, fascia, or tendon of the right index finger. The injury occurred at the wrist or hand level, and the specific nature of the original injury is not documented.

Apply this code when documenting a patient presenting with a current problem directly resulting from a past, unspecified injury to the extensor structures of the right index finger. This is appropriate for conditions like chronic pain, stiffness, weakness, or deformity that are sequelae of the original trauma.

• Requires a seventh character "S" to indicate sequela, meaning the current condition is a residual effect of a previous injury.
• Only use when the specific nature of the original injury (e.g., laceration, strain, rupture) is unknown or not documented.
• Ensure documentation clearly links the current complaint to a prior injury of the right index finger's extensor mechanism at the wrist/hand level.
