Your J codes should distinguish Paraguard and Mirena IUDs. Answer: • J7300 (Intrauterine copper contraceptive) for copper-bearing IUDs • J7302 (Levonorgestrel-releasing intrauterine contraceptive system, 52 mg) for progestin-releasing IUDs. If you're submitting a supply code to a private payer that accepts S codes (such as Blue Cross Blue Shield), you can report S4981 (Insertion of levonorgestrelreleasing intrauterine system) alternatively for a progestin-releasing IUD. You can bill for the supplies only if your practice purchases them ahead of time and keeps a supply in the office, points out Veronica Antonelli, coding and compliance coordinator for Women's Care Florida in Tampa Bay. Some payers require practices to purchase this device through a specified process where the vendor bills the payer directly. If that's the case, you shouldn't bill for the supply.
