Heads up: "Functional," "selective," and "radical" refer to the same procedure. Thinking you know thyroidectomy codes through and through may set you up for disaster. You really have to study the code descriptors and know the terminology associated with neck dissection to accurately code these procedures. Tip: Decide Whether to Report Dissections Challenge yourself with the following examples. Suppose your otolaryngologist removes both thyroid lobes with the isthmus and pyramid lobe tissue. He also identifies and excises all enlarged lymph nodes. The malignancy has not spread significantly, so the otolaryngologist excises only a few selected lymph nodes. As a result, he performs a thyroidectomy with limited neck dissection. What CPT code(s) should you report, and should you report a separate code for the dissection? Answer 1: What if the physician states in the operative note that she performed a "central neck dissection?" What would you code in this situation? Answer 2: Let's try another example. During a total thyroidectomy, an otolaryngologist dissects all the levels of lymph nodes and must sacrifice the spinal accessory nerve, jugular vein and sternocleidomastoid muscles to remove a malignant lymphatic chain. What CPT code(s) should you report, and should you report a separate code for the dissection? Answer 3: In this case, report only the thyroidectomy with radical neck dissection with 60254 (Thyroidectomy, total or subtotal for malignancy; with radical neck dissection). By definition, you shouldn't separately report the radical neck dissection (38720, Cervical lymphadenectomy [complete]). CPT, however, throws you a curve ball when your physician combines thyroidectomy with modified radical neck dissection. None of the thyroidectomy codes specify this combination, which you'll have to code out separately. Suppose an otolaryngologist removes both thyroid lobes. But when removing a malignant lymphatic chain, she manages to preserve the spinal accessory nerve, jugular vein, and sternocleidomastoid muscles. What CPT code(s) should you report, and should you report a separate code for the dissection? Answer 4: Don't forget to use modifier 50 (Bilateral procedure) if the physician performs the modified radical neck dissection bilaterally. Watch Out for Other Terms Although op report titles clue you into how to code a procedure, otolaryngologists may use several monikers for a modified radical neck dissection. For instance, "functional neck dissection is the same as a modified radical neck dissection," Cobuzzi says. Another name your surgeon might use is selective neck dissection. The code for these is 38724. Surprise: Suppose, an otolaryngologist removes the lymph nodes as well as the sternocleidomastoid muscle, the spinal accessory nerve, and the internal jugular vein. This is a radical neck dissection (38720). Note that you should report 38700 when the surgeon removes the nodes above the hyoid only.
