Strain extn musc/fasc/tend at forarm lv, unsp arm, sequela

This code signifies a chronic or residual condition resulting from a previous strain injury to the extensor muscles, fascia, or tendons in the forearm. It indicates that the specific arm affected (left or right) was not documented at the time of the original injury or subsequent treatment. The injury involves muscles responsible for extending the wrist and fingers.

This code is appropriate for documenting the long-term effects or complications of a forearm extensor strain when the laterality of the original injury is unknown or unspecifiable. It is used when a patient presents for follow-up care related to persistent pain, weakness, or functional limitations stemming from a past strain.

• Always attempt to clarify the laterality (left or right arm) if possible to use a more specific code.
• Ensure documentation clearly links the current condition to a previous strain injury.
• This "S" seventh character indicates a sequela, meaning the patient is experiencing residual effects of the original injury.
