Strain of unsp quadriceps muscle, fascia and tendon, sequela

This code signifies a long-term or late effect resulting from a previous injury to the quadriceps muscle, its surrounding fascia, or associated tendons, where the specific quadriceps muscle involved was not documented. These sequelae can include chronic pain, weakness, stiffness, or functional limitations that persist after the initial acute phase of the strain has resolved.

This code is appropriate for documenting residual conditions directly attributable to a past quadriceps strain when the specific muscle (e.g., rectus femoris, vastus medialis) was not identified in the original injury. It should be used when the patient is presenting for treatment of these persistent issues, not for the initial acute injury.

• Always assign an additional code to specify the nature of the sequela (e.g., chronic pain, muscle weakness).
• Ensure documentation clearly links the current condition to a previous quadriceps strain.
• Avoid using this code for acute or subacute injuries; it is strictly for late effects.
