  1. When selecting the CPT code for repair of a lacerated peripheral nerve, the primary determinants are:

    Answer: The specific nerve involved and whether it is a primary or secondary repair

    CPT nerve repair codes are selected based on the specific nerve repaired and repair timing (primary/fresh vs. secondary/delayed or with grafting).

  2. Which statement correctly describes add-on codes used for additional spinal levels?

    Answer: They represent additional work at extra levels and must accompany a primary procedure code

    Add-on codes (marked with '+') represent additional services performed with a primary procedure; they cannot be billed independently and are exempt from modifier -51.

  3. Nerve conduction studies performed on 3–4 nerves are reported with which CPT code?

    Answer: 95908

    CPT 95908 describes nerve conduction studies covering 3–4 studies (nerves tested), and is selected based on the total number of nerve studies performed.

  4. Destruction by neurolytic agent of a peripheral nerve branch not described by a more specific CPT code (such as the greater occipital nerve) is reported with:

    Answer: 64640

    CPT 64640 describes destruction by neurolytic agent of any other peripheral nerve or branch not covered by a more specific code.

  5. Creation of a ventriculoperitoneal (VP) shunt is reported with which CPT code?

    Answer: 62223

    CPT 62223 describes creation of a shunt including ventriculoperitoneal (VP shunt), ventriculopleural, or ventriculoatrial configurations.

  6. Stereotactic brain biopsy performed using CT/MRI guidance WITHOUT a stereotactic frame is reported with:

    Answer: 61751

    CPT 61751 describes a stereotactic biopsy of the brain with CT and/or MRI guidance performed without a stereotactic frame (frameless navigation).

  7. Transforaminal epidural injection of a steroid at the cervical level (single level) with imaging guidance is reported with:

    Answer: 64479

    CPT 64479 describes injection of an anesthetic or steroid via transforaminal approach at the cervical or thoracic level, single level, with imaging guidance.
