Strain of unsp quadriceps muscle, fascia and tendon, init

This code signifies a muscle strain affecting the quadriceps group, its surrounding fascia, or associated tendons, where the specific quadriceps muscle involved is not documented. It indicates an acute injury, representing the initial phase of treatment.

Apply this code when a patient presents with a quadriceps strain, and the medical record does not specify which of the four quadriceps muscles (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius) is affected. This is appropriate for the initial visit for this injury, such as in an emergency department or initial physician consultation.

• Ensure the documentation explicitly states "unspecified" or lacks detail regarding the specific quadriceps muscle.
• Confirm this is the patient's first encounter for this particular injury; subsequent encounters will require a different seventh character.
• If a specific quadriceps muscle is identified (e.g., rectus femoris), a more precise code should be selected.
