Typically, Delta will not pay for anesthesia outside of the oral surgery/dentist office.
After researching, I did find the following (from the AAOMS).......
USING DENTAL CODES ON MEDICAL CLAIMS
In general, CPT codes are not used on ADA forms, and CDT codes are not used on CMS 1500
(Medical) forms. However, some medical carriers may direct that you use CDT codes on a
CMS 1500 form for “dental” procedures which do not have an applicable CPT code
(e.g. third molars). In those situations, they may also request use of CDT anesthesia codes.
The presence of an anesthesia code, or any procedure code, does not guarantee payment for these services. It is crucial for the OMS practitioner and his/her staff to understand the intricacies of reimbursement for anesthesia services by each carrier, managed care organization, and Medicare.(end)
Unless the patient has an oral surgery rider on their medical policy, it is my experience that anesthesia is usually not covered out of the oral surgery office.
