Strain msl/tnd lng extn msl toe at ank/ft lev, r foot, sqla

This diagnosis code indicates a prior injury to the long extensor muscle and its tendon in the right foot, specifically at the ankle or foot level, where the patient is now experiencing persistent symptoms or complications as a direct result of that original strain. These sequelae could include chronic pain, weakness, limited range of motion, or other long-term functional impairments.

Apply this code when documenting a patient presenting with ongoing issues stemming from a previously sustained strain to the long extensor muscle of the right foot. This is appropriate for follow-up visits addressing chronic symptoms or complications that are directly attributable to the original injury, rather than an acute event.

• Ensure documentation clearly links the current symptoms to a past strain of the specified muscle/tendon.
• This "S" seventh character indicates sequela, meaning the acute injury has resolved, but residual effects persist.
• Do not use for acute or initial encounters; look for codes with "A" (initial encounter) or "D" (subsequent encounter) for those situations.
