D1353Sealant Repair - Per Tooth

What This Code Covers

D1353 covers the repair of a sealant that was previously placed on a tooth. Over time, sealants can partially or completely wear away, chip, or debond. When this happens, the remaining sealant may be removed and a new sealant reapplied, or additional sealant material may be added to fill in the gaps. This code is billed per tooth.

Billing Guide

Bill this code when:

• A previously placed sealant has partially or fully lost and needs repair
• The tooth is still free of decay and only the sealant needs to be replaced
• The repair involves removing remnants of the old sealant and applying new material
• The tooth was evaluated and the sealant was found to be deficient

Do not bill this code when:

• A brand new sealant is being placed on a tooth that never had one. Use D1351
• Decay has developed under or around the failed sealant requiring a restoration
• The original sealant was placed recently and the repair is within the warranty period covered by the original code
• The payer does not recognize D1353 and requires rebilling as D1351

Insurance and Denial Prevention

Key Payer Rules:

• Not all payers recognize D1353 as a separate code. Some require sealant repairs to be billed as D1351
• When covered, frequency limits for sealants may apply to both D1351 and D1353 combined
• Some payers have a waiting period after the original sealant before they cover a repair
• Medicaid programs vary in their coverage of sealant repairs

Common Denials and How to Respond:

• Code not recognized → Contact the payer. They may require billing sealant repairs as D1351 with a narrative.
• Frequency exceeded → Verify the combined frequency limit for sealants and sealant repairs on the plan.
• Too soon after original placement → Some plans require a waiting period. If the sealant failed prematurely, document the clinical finding and appeal.
