Coverage Summary

Scope: This policy (Policy Number DCP009.12, Status: CURRENT) defines indications and non-indications for non‑surgical endodontic procedures including direct and indirect pulp caps, therapeutic pulpotomy, partial pulpotomy for apexogenesis, apexification/recalcification, pulpal regeneration, pulpal debridement (pulpectomy), pulpal therapy for primary teeth (resorbable filling), endodontic (root canal) therapy, treatment of root canal obstruction (non‑surgical access), incomplete endodontic therapy, internal root repair of perforation defects, and retreatment of previous root canal therapy. It also provides an applicable CDT procedure code list and notes on inclusive intra‑operative services.

Overview: Non‑surgical endodontic treatment uses chemical and mechanical management of the root canal system to promote healing and repair of periradicular tissues; additional surgical procedures may be required for posts, obstructions, radicular defects, aberrant canal morphology, ledges, or perforations. Coverage stance is mixed (procedures are indicated or not indicated based on the specific clinical criteria listed in the policy), and procedural coding guidance is provided in the applicable CDT list and inclusions section.

Key thresholds and dates

Root calcification extentComplete calcification of 50% or more of root length

Retreatment apex distanceCanal fill appears to extend to a point shorter than 2 millimeters from the apex (indicator for retreatment)

Primary tooth root bone requirementTooth root lies in at least 25% bone (for pulpal therapy in primary teeth)

Retreatment is indicated when ANY of the following apply:

ANY of the following

Canal fill appears to extend to a point shorter than 2 millimeters from the apex, or extends significantly beyond the apex
Fill appears to be incomplete
Tooth is sensitive to pressure and percussion or other subjective symptoms
Placement of a post has the potential to compromise the existing obturation or apical seal of the canal system

Background and Definitions

Background: Non‑surgical endodontic treatment is described as the use of biologically acceptable chemical and mechanical therapies of the root canal system to promote healing and repair of the periradicular tissues. The policy notes that additional surgical procedures may be required to remove posts and manage canal obstructions, radicular defects, aberrant canal morphology, ledges, or perforations. Pursuant to CA AB2585 the policy specifically states that nonpharmacological pain management strategies should be encouraged if appropriate.

Term	Definition
Apexogenesis
The vital pulp therapy performed to encourage continued physiological formation and development of the tooth root. (ADA)
Direct Pulp Cap
A procedure in which the exposed vital pulp is treated with a therapeutic material, followed with a base and restoration, to promote healing and maintain pulp vitality. (ADA)
Endodontics
The branch of dentistry which is concerned with the morphology, physiology, and pathology of the human dental pulp and periradicular tissues. Its study and practice encompass the basic and clinical sciences including biology of the normal pulp, the etiology, diagnosis, prevention and treatment of diseases and injuries of the pulp and associated periradicular conditions. (ADA)
Indirect Pulp Cap
A procedure in which the nearly exposed pulp is covered with a protective dressing to protect the pulp from additional injury and to promote healing and repair via formation of secondary dentin. (ADA)
Perforation
The mechanical or pathologic communication between the root canal system and the external tooth surface. (AAE)
Pulpal Debridement (Pulpectomy)
The complete removal of vital and non-vital pulp tissue from the root canal space. (ADA)
Regenerative Endodontics
Biologically based procedures designed to physiologically replace damaged tooth structures, including dentin and root structures, as well as cells of the pulp-dentin complex. (AAE)
Recalcification
A procedure used to encourage biologic root repair of external and internal resorption defects. (ADA)
Therapeutic Pulpotomy
The removal of a portion of the pulp, including the diseased aspect, with the intent of maintaining the vitality of the remaining pulpal tissue by means of a therapeutic dressing. (ADA)
