most all carriers are going to first see this as a cosmetic procedure as doctors tend to agree/disagree on the medical necessity.
Doctors disagree over how hemangiomas should be dealt with. The answer may depend on whether you see a dermatologist, plastic surgeon, pediatrician, or other specialist. Because many of the smaller birthmarks resolve on their own with no intervention, most doctors agree that you should leave small hemangiomas that are not growing alone, especially if they are on skin normally covered by clothing.
The medical necessity argument are some as discribed below.
Hemangiomas that require early aggressive treatment include those that are cosmetically deforming, growing rapidly or obstructing vision, hearing, breathing, eating or any other body function. Hemangiomas on the lower face and neck may later block internal airways. Large facial hemangiomas may cause psychosocial impairment. Also, larger hemangiomas that are left alone to regress (shrink away over years) will eventually look better if the resulting saggy, stretched out skin and fatty tissue is surgically removed.
Because I am more experienced on the coding side then billing my suggestion would be to submit the chart notes along with the initial submission of your bill in hopes that it wont get denied as ''non covered' the first tiem.. Hopefully some of the billing experts on this form can adivse on the billing techniques.
