Strain extn musc/fasc/tend l idx fngr at forarm lv, sequela

This code signifies a chronic or late effect of an injury to the extensor muscle, fascia, or tendon of the left index finger, specifically at the forearm level. It indicates that the patient is experiencing residual symptoms or complications from a previously sustained strain in this anatomical area.

Use this code when documenting conditions such as chronic pain, weakness, limited range of motion, or other long-term sequelae directly resulting from a past strain of the left index finger's extensor mechanism at the forearm. This applies after the acute phase of the initial injury has passed.

• Requires an additional code to identify the specific sequela (e.g., chronic pain, muscle weakness).
• Ensure documentation clearly links the current condition to a previous strain of the specified anatomical site.
• Do not use for acute or initial encounters of a strain; this code is exclusively for sequelae.
