Venous Malformation

Question:

I am trying to provide the most accurate code in order to get a procedure through pre-determination for insurance. The patient has had two prior sclerotherapy sessions of a right triceps venous malformation. The patient still has residual episodic acute pain, with some component of muscle dysfunction. The pain is not relieved by dependent positioning or by anti-inflammatories. The ultrasound that was done last shows the malformation without flow, therefore the best course would be to perform cryoablation of the lesion. Would this be reported with unlisted code 37799?
