Unsp injury of unsp quadriceps musc/fasc/tend, init

This code signifies an injury to any part of the quadriceps muscle group, its surrounding fascia, or its tendons, where the specific muscle or tendon involved is not documented. It indicates that the injury is acute and the patient is receiving initial treatment for it.

Use this code when documentation clearly states a quadriceps injury but lacks specificity regarding which of the four quadriceps muscles (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius) or which specific tendon is affected. This is appropriate for initial evaluations of new quadriceps strains, tears, or contusions where further diagnostic details are pending.

• Only use this code when the specific quadriceps muscle or tendon is truly unspecified in the medical record.
• Always strive for a more specific code if the documentation allows (e.g., S76.11_ for rectus femoris).
• The "A" suffix indicates an initial encounter for active treatment.
