Code 38999 (unlisted CPT due to direct approach) vs. 2014 transcather codes... Code 37244 does not seem to fit lymphatic malformation direct approach embolizations. "Ultrasound-guided needle placement: Ultrasound evaluation showed numerous predominantly microcystic changes in a thicken soft tissues in the submandibular and right facial region and in the tongue base. A few macrocystic changes are present. Under ultrasound guidance, 18 gauge catheters were carefully inserted into multiple areas of the macro and microcystic areas. Percutaneous embolization: 6 ml of 3% sodium tetradecyl sulphate mixed with 10 ml of room air and a foamed emulsion was made. The sclerosant was slowly injected with ultrasound guidance at 6 lymphatic micro and macrocystic malformation sites. Firm manual compression was applied after needle withdrawal for 3 minutes. A small amount of fluid was aspirated prior to the cyst injections."
