Strain of intrns msl/tnd at ank/ft level, unsp foot, sequela

This code describes a chronic or late effect of an injury involving a strain to the small muscles and/or tendons located within the ankle or foot itself. It indicates that the initial injury has resolved, but the patient continues to experience residual symptoms or complications directly related to that past strain. The specific foot affected is not documented.

Apply this code when a patient presents with ongoing pain, weakness, instability, or other long-term issues stemming from a previously sustained strain of an intrinsic muscle or tendon in the ankle or foot. This would be used after the acute and subacute phases of the original injury have passed, and the current encounter addresses the sequelae.

• Always use an additional code to identify the specific sequela, such as chronic pain or functional limitation.
• Ensure documentation clearly states the current condition is a residual effect of a past strain, not an acute injury.
• This code is for an unspecified foot; if the laterality is known, a more specific code should be chosen.
