Major Restorative Services (cont.)
Benefit Limitations for Class C Major Restorative Services
1. Diagnostic casts (study models) taken in conjunction with restorative procedures are considered integral
2. Pin retention is covered only when reported in conjunction with an eligible restoration.
3. An amalgam or resin restoration reported with a pin (D2951), in addition to a crown, is considered to be a pin buildup
(D2950).
4. The charge for a crown or onlay should include all charges for work related to its placement including, but not limited
to, preparation of gingival tissue, tooth preparation, temporary crown, diagnostic casts (study models), impressions, try-
in visits, and cementations of both temporary and permanent crowns.
5. Onlays, permanent single-crown restorations, and posts and cores for members 12 years of age or younger are excluded
from coverage unless specific rationale is provided indicating the reason for such treatment (e.g., fracture, endodontic
therapy, etc.) and if approved by the contractor.
6. Cast posts and cores (D2952) are processed as an alternate benefit of a prefabricated post and core. The patient is
responsible for the difference between the dentist's charge for the cast post and core and the amount paid by the
contractor for the prefabricated post and core.
7. Replacement of crowns, onlays, buildups, and posts and cores is covered only if the existing crown, onlay, buildup, or
post and core was inserted at least five years prior to the replacement and satisfactory evidence is presented that the
existing crown, onlay, buildup, or post and core is not and cannot be made serviceable. Satisfactory evidence must show
that the existing crown, onlay, buildup, or post and core is not and cannot be made serviceable. The five-year service
date is measured based on the actual date (day and month) of the initial services versus the first day of the initial service
month.
8. Onlays, crowns, and posts and cores are payable only when necessary due to decay or tooth fracture. However, if the
tooth can be adequately restored with amalgam or composite (resin) filling materials, payment will be made for that
service. This payment can be applied toward the cost of the onlay, crown, or post and core.
9. When performed as an independent procedure, the placement of a post is not a covered benefit. Posts are only eligible
when provided as part of a buildup for a crown and are considered integral to the buildup.
10. Services or treatment for the provision of an initial prosthodontic appliance (i.e., fixed bridge restoration, implants,
removable partial or complete denture, etc.) when it replaces natural teeth extracted or missing, including congenital
defects, prior to effective date of coverage are not eligible for coverage.
