Also, you need to check your Medicaid guidelines as well if the patient has Medicaid. What Medicare has as guidelines is not always the case with Medicaid and vica versa. Also, check for any NCDs that relate to the product. For example, Medicare has an NCD for Mobility Assistive Equipment (MAE) (280.3) that payers will use for why a denial was valid.
My advice, as Doreen stated, get to know the guidelines as most denials happen because of a guideline requirement that was not met verses a coding error.
Good Luck! Hope this helps.
