Inj intrns musc/fasc/tend l idx fngr at wrs/hnd lv, sequela

This code signifies a long-term complication or residual effect stemming from a previous injury to the intrinsic muscles, fascia, or tendons of the left index finger. This injury occurred specifically at the wrist or hand level, affecting the fine motor control and function of the digit. The sequela indicates that the initial acute injury has resolved, but persistent issues remain.

This code is appropriate for documenting chronic pain, weakness, stiffness, limited range of motion, or other lasting functional impairments of the left index finger due to a past injury to its intrinsic structures. It should be used when the patient is presenting for treatment or evaluation of these ongoing problems, not for the initial acute injury. This code is also applicable when a patient requires ongoing therapy or management for these residual effects.

• Always ensure documentation clearly links the current condition to a previous injury of the intrinsic muscles, fascia, or tendons of the left index finger.
• This "S" seventh character indicates a sequela, meaning the initial injury has healed, but its lasting effects are being treated.
• Do not use this code for acute injuries; instead, refer to the appropriate acute injury code for the initial encounter.
