Read the first 7 Periodontal Procedures Coding flashcards as text

  1. What CDT code is reported for osseous surgery involving four or more teeth per quadrant?

    Answer: D4260

    D4260 describes osseous surgery (bone reshaping and recontouring) when performed on four or more teeth per quadrant, while D4261 is used for one to three teeth.

  2. Which procedure is described by CDT code D4249?

    Answer: Clinical crown lengthening — hard tissue

    D4249 describes clinical crown lengthening involving hard tissue (bone removal), which is performed to expose sufficient tooth structure for restorative procedures.

  3. Which CDT code is used to report a free soft tissue graft procedure for the first tooth or edentulous area?

    Answer: D4271

    D4271 is used for a free soft tissue graft (harvested and completely detached from the donor site) for the first tooth, implant, or edentulous area treated.

  4. What CDT code describes the localized delivery of antimicrobial agents into periodontal pockets as an adjunct to scaling and root planing?

    Answer: D4381

    D4381 is the code for localized delivery of antimicrobial agents (such as chlorhexidine chip or doxycycline gel) into periodontal pockets as an adjunct to SRP.

  5. What does CDT code D4211 describe?

    Answer: Gingivectomy or gingivoplasty involving four or more teeth per quadrant

    D4211 is used for gingivectomy or gingivoplasty when performed on four or more teeth per quadrant; D4212 is used when one to three teeth are involved.

  6. Which CDT code describes guided tissue regeneration using a resorbable barrier membrane?

    Answer: D4266

    D4266 is used for guided tissue regeneration with a resorbable barrier, while D4267 is used when a non-resorbable barrier is placed and requires subsequent removal.

  7. Which CDT code is appropriate for reporting provisional intracoronal splinting of periodontally involved teeth?

    Answer: D4320

    D4320 is used for provisional intracoronal splinting, where stabilization involves preparation within the tooth structure, as opposed to D4321 which is extracoronal.
