Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Indications for coverage

Foreign body obstruction: Blockage of the root canal by a foreign body (including, but not limited to, separated instrument or broken post).
Calcified canal: Calcification of 50% or more of the length of the tooth root (calcification from the root tip to the pulp chamber is 50% or more occluded).
Pulp stones: Presence of pulp stones requiring formation of a pathway to achieve an apical seal without surgical intervention.

Select Health will deny the root canal obstruction (non‑surgical access) procedure when the required clinical documentation and radiographic verification are not submitted. Specifically, approval requires chart notes and a radiographic image that shows a file in place indicating the position of the blockage to verify the indicated condition. If those materials are not provided, the service will be denied as inclusive to the primary endodontic procedure.

Provider Actions and Requirements

Prior Authorization

Prior Authorization Required

Prior Authorization / Approval Required — Approval requires submission of chart notes and a radiograph demonstrating the obstruction. Follow commercial plan rules.

Submit chart notes documenting the condition
Submit a radiographic image showing a file in place indicating the position of the blockage

Documentation Required

Provider Documentation Required

Provider must submit supporting documentation with the request. Failure to provide required documentation will result in denial.

Chart notes verifying the obstruction or calcification
Radiograph showing file in place confirming blockage position

Denial Risk

Denial Risk if Documentation Not Provided

Documentation-driven Denial Risk — If chart notes and a radiographic image verifying the blockage are not provided, the procedure will be denied as inclusive to the primary endodontic procedure.

Denial will occur when chart notes and radiographic evidence are not submitted

Background

Non‑surgical access for treatment of a root canal obstruction is an alternative to surgical intervention intended to create a pathway to achieve an apical seal when a root canal is non‑negotiable. Covered situations include obstruction by a foreign body (for example, a separated instrument or broken post) or significant calcification. For the latter, the policy defines the threshold as calcification of 50% or more of the length of the tooth root. Imaging that documents the obstructing pathology and supports the need for non‑surgical access is required for reimbursement.
