Strain msl/fasc/tnd post grp at thi lev, unsp thigh, sequela

This code signifies a chronic or late-effect injury to the muscles, fascia, or tendons located at the back of the thigh, such as the hamstrings. It indicates that the initial acute injury has resolved, but the patient continues to experience residual symptoms or complications related to the strain. The specific thigh (left or right) is not documented.

Use this code when documenting a patient presenting with ongoing pain, weakness, or functional limitations in the posterior thigh due to a previously sustained muscle, fascia, or tendon strain. This applies when the acute phase of the injury has passed, and the current encounter addresses the long-term consequences.

• Always sequence the sequela code after the code for the primary condition or injury that caused the sequela, if applicable.
• Ensure documentation clearly states the injury is a "sequela," "late effect," or describes chronic symptoms resulting from a past strain.
• Avoid using this code for acute or initial encounters of a thigh strain; specific acute strain codes should be used instead.
