Codes and Timelines
Submitting Requests, Incomplete Info, and Denials
Submitting prior authorization requests
Providers and facilities must be able to submit prior authorization requests at any time, including outside normal business hours. Carriers (or their designated/contracted representatives) must provide a secure online process for participating providers or facilities to complete prior authorization requests and upload documentation (effective November 1, 2019). Carriers must also maintain a system documenting information and supporting evidence submitted during prior authorization requests and, upon request or when information is transmitted telephonically, provide written acknowledgments of receipt of documents or telephonic communications.
- Allow submission of prior authorization requests at all times, including outside normal business hours.
- Provide a secure online process for participating providers/facilities to complete requests and upload documentation (effective Nov. 1, 2019).
- Document and retain all information and supporting evidence submitted while requesting prior authorization until claim paid or appeals exhausted.
- Provide written acknowledgment of documents upon request and of telephonic transmissions.
Handling requests with incomplete information
If a prior authorization request is missing necessary information, the carrier or its designated/contracted representative must inform the provider or facility what additional information is needed and the deadline for its submission. Time frames for determinations pause until the carrier has the necessary information to make a decision; once received (or the deadline for receipt expires), the applicable prior authorization time frames apply and the carrier must make a decision within the required period.
- Inform the provider/facility what additional information is needed and the submission deadline when a request lacks necessary information.
- Determination time frames are suspended until the carrier receives the necessary information; once received (or the deadline passes), the initial statutory time frames govern.
Denial notification requirements
When a prior authorization request is denied, the carrier must state whether it is approved or denied and, for denials, provide the specific reason in clear and simple language. The denial must include clinical review criteria if the denial is based on those criteria, the department and credentials of the individual with authorizing authority, a phone number to contact that authorizing authority, and notice of the enrollee's appeal rights and process; written notice must be provided to the provider/facility and the enrollee (oral decision permitted if followed by written notice).
- State approval or denial; for denials, give the specific reason in clear and simple language.
- Provide clinical review criteria when the denial is based on those criteria.
- Include the department and credentials of the authorizing individual and a contact phone number.
- Provide notice of the enrollee's appeal rights and process and deliver written notice to the provider/facility and enrollee (oral allowed if followed by written).

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.
