Is it appropriate to code 49185 or 37241? "PROCEDURE: Lymphatic malformation sclerotherapy. Ultrasound mapping confirmed the presence of lymphatic malformation within area of concern, comprised of 3 dominant large macrocysts and multiple smaller macrocysts. The largest macrocyst was accessed using ultrasound guidance and a 20 gauge Angiocath needle. The cyst was aspirated to completion and injected with a dilute solution of Sotradecol 3%. The Sotradecol was left to dwell for approximately 5 minutes and then aspirated. The cyst was then injected with a smaller volume of the contrast-opacified doxycycline solution than was initially aspirated. The two remaining dominant macrocysts were each treated in a similar fashion. The remaining smaller macrocysts were accessed under ultrasound guidance, aspirated, and then injected with a slightly smaller volume of doxycycline solution. Post procedure ultrasound and radiograph confirmed the presence of contrast opacified doxycycline solution within the region of concern."
