Inj intrinsic msl/tnd at ank/ft level, right foot, sequela

This code describes a long-term or late effect of an injury to a specific intrinsic muscle or tendon within the right ankle or foot. These are muscles and tendons that originate and insert entirely within the foot, and the injury is not further specified as a sprain, strain, or laceration. The "sequela" designation indicates that the initial acute injury has resolved, but the patient is still experiencing residual effects.

Use this code when documenting a chronic or residual condition resulting from a past injury to an intrinsic muscle or tendon of the right foot. This applies when the specific nature of the original injury (e.g., tear, rupture) is not precisely known or documented, but the lasting consequences are being treated. Examples include chronic pain, weakness, or limited range of motion directly attributable to the old injury.

• Ensure documentation clearly links the current condition to a previous injury of an intrinsic muscle or tendon in the right foot.
• Only use the "S" seventh character for sequela codes when the acute phase of the injury has passed and the patient is being treated for the residual effects.
• Verify that the injury is to an intrinsic muscle or tendon, meaning it originates and inserts within the foot itself, rather than an extrinsic muscle with a tendon extending into the foot.
