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

This code describes a chronic or late effect of an injury to a flexor muscle, fascia, or tendon in the forearm, where the specific arm (left or right) is not documented. This indicates a residual problem or complication directly resulting from an initial strain, rather than the acute injury itself.

Use this code when a patient presents with a long-term consequence or complication from a previously sustained strain of a forearm flexor muscle, fascia, or tendon. This is appropriate for conditions like persistent pain, weakness, limited range of motion, or scar tissue formation that are directly attributable to an old strain.

• Always sequence this "S" code after the code describing the specific sequela (e.g., chronic pain, muscle weakness).
• Ensure documentation clearly links the current condition to a past forearm flexor strain.
• Avoid using this code for acute or initial injury encounters; those require the acute strain codes without the "S" seventh character.
