Dental offices are heading into 2027 with another round of insurance changes to track.
In October, Healthcare Dive reported that several major Medicare Advantage carriers are reducing dental allowances for 2027. UnitedHealthcare reductions affect almost 70% of its members. CVS-owned Aetna reduced dental benefits for 36% of members. Shifts like these affect the coverage patients bring into the office and place more pressure on eligibility checks before treatment begins.
And what about reimbursement? An ADA Health Policy Institute poll found that more than half of dentists entering 2026 named insurance among their top concerns, including low reimbursement and delayed or denied payments. AS Bertram Hughes, D.D.S., told ADA News, “Many of us have experienced real declines in reimbursement.”
Dental Insurance With Medicare Has More Billing Variables
Traditional Medicare still excludes routine dental care in general. Coverage has expanded, however, for certain dental services considered integral to the success of covered medical treatment.
Under current CMS Medicare dental coverage rules, eligible situations include dental care connected with organ transplants and cardiac valve procedures. This coverage also extends to specified cancer treatment and other qualifying medical care.
The billing rules require more coordination than a standard dental claim. Since July 1, 2025, claims for covered dental services that are inextricably linked to medical care require a KX modifier. Claims submitted on the 837D dental format, meanwhile, also require an ICD-10 diagnosis code. Documentation must demonstrate the medical connection and care coordination between providers. It’s a lot.
Dental insurance billing and coding staff are in unfamiliar territory. Well, familiar in the sense that paperwork is burdensome, but unfamiliar because even more is now required. Offices need to identify the patient’s type of Medicare coverage and confirm the benefit involved. Even with that in hand, staff need the right supporting documentation before a claim leaves the practice.
CDT 2027 Changes Affect Dental Billing
Medicare changes are arriving alongside annual CDT updates. The ADA approved a whopping 67 changes for CDT 2027, including 28 new codes and 33 revisions. The changes take effect January 1, 2027.
Accurate coding still does not guarantee payment. Rather, benefit limitations and payer policies will determine reimbursement — and only after the procedure is reported. Downcoding and documentation gaps create plenty of denials or lower payments.
As a result, there’s a growing need for dental insurance billing and coding classes that address the rules staff encounter in daily revenue-cycle work.
