Important note


This Clinical Policy Bulletin determines whether certain services or supplies are medically necessary, experimental, and investigational, or cosmetic. Aetna® has reached these conclusions based upon a review of currently available clinical information (including clinical outcome studies in the peer-reviewed published medical literature, regulatory status of the technology, evidence -based guidelines of public health and health research agencies, evidence-based guidelines and positions of leading national health professional organizations, views of physicians practicing in relevant clinical areas, and other relevant factors).


Aetna makes no representations and accepts no liability with respect to the content of any external information cited or relied upon in the Bulletin.  The discussion, analysis, conclusions, and positions reflected in this Bulletin, including any reference to a specific provider, product, process or service by name, trademark, manufacturer, constitute an opinion by Aetna and are made without any intent to defame.


Aetna expressly reserves the right to revise these conclusions as clinical information changes, and welcomes further relevant information including correction of any factual error. CPBs include references to standard HIPAA compliant code sets to assist with search functions and to facilitate billing and payment for covered services. New and revised codes are added to the CPBs as they are updated. When billing, you must use the most appropriate code as of the effective date of the submission. Unlisted, unspecified and nonspecific codes should be avoided.  


Each benefit plan defines which services are covered, excluded and subject to dollar caps or other limits. Members and their dentists will need to refer to the member's benefits plan to determine if any exclusions or other benefits limitations apply to this service or supply.


The conclusion that a particular service or supply is medically necessary does not guarantee that this service or supply is covered (that is, will be paid for by Aetna) for a particular member. The member's benefits plan determines coverage. Some plans exclude coverage for services or supplies that we consider medically necessary. If there is a discrepancy between this policy and a member's plan of benefits, the benefits plan will govern. In addition, coverage may be mandated by applicable legal requirements of a state, the federal government or CMS for Medicare and Medicaid members.

We consider the placement of a preventive resin restoration (PRR) to be a treatment for caries found in the pits and fissures in a patient documented to be at moderate-to-high risk of caries. Aetna’s policy is that if decay is present on pit and fissures of permanent teeth and it extends into the dentin, the restoration is considered a posterior composite. If the decay (active cavitated lesion) does not extend into the dentin, it is considered a preventive resin restoration. The PRR procedure includes placement of a sealant in any radiating non-carious fissures or pits.




The preventive resin restoration (a combination of composites and/or sealants) is a treatment for caries found in the pits and fissures of posterior permanent teeth in a documented moderate to high caries risk patient when the carious lesion is isolated to the enamel. A patient's caries risk assessment may be evaluated and documented by a variety of methods. 


The use of preventive resin restorations is generally governed by the desire to treat small lesions conservatively, and they are usually placed in the nonstress-bearing regions of the dentition.
