Strain msl/tnd lng flxr msl toe at ank/ft lev, l foot, sqla

This code signifies a long-term or residual effect resulting from a previous injury to the long flexor muscle and its tendon in the left foot, specifically at the ankle or foot level. This indicates that the initial strain has healed, but the patient continues to experience ongoing symptoms or functional limitations directly attributable to that past injury.

Use this code when documenting a patient presenting with chronic pain, weakness, stiffness, or other persistent issues in the left foot or ankle that are a direct consequence of a previously diagnosed strain of the long flexor muscle. This applies to follow-up visits where the acute phase of the injury has passed, but the sequelae are still being managed.

• Ensure documentation clearly links the current symptoms to a past strain of the specified muscle/tendon.
• This code requires a seventh character "S" for sequela, indicating a late effect.
• Do not use for acute or initial encounters of a muscle/tendon strain.
