Initiate Open Negotiation and (if needed) IDR — how, when, and where to send requests

If the 30-day negotiation does not resolve the dispute, providers may generally initiate the Independent Dispute Resolution (IDR) process within 4 days after the end of the negotiation period; follow federal IDR initiation requirements. Send notices and communications to the Provider Appeals contact listed or call Customer Support with questions.

Key Definitions
OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.
