Strain extensor musc/fasc/tend r thm at wrs/hnd lv, sequela

This code signifies a past injury involving a strain to the extensor muscles, fascia, or tendons of the right thumb, specifically at the wrist and hand level. The "sequela" designation indicates that this code is used to report a current condition that is a residual effect or complication of the original strain, rather than the acute injury itself.

This code is appropriate when a patient presents with ongoing symptoms such as chronic pain, weakness, limited range of motion, or instability in the right thumb, and these symptoms are directly attributed to a previously sustained extensor strain. It should be used after the initial acute phase of the injury has passed and the patient is experiencing long-term effects.

• Always ensure documentation clearly links the current symptoms to a prior extensor strain of the right thumb.
• Do not use this code for the initial acute injury; a different code would be appropriate for the acute phase.
• Consider additional codes for specific residual symptoms, such as chronic pain (e.g., G89.29), if documented.
