25-999 Streamlining Prior Authorization: Simplifying Processes for Better Efficiency
Date: 09/24/25
New code updates to minimize administrative burden and enhance patient care
In our continuous effort to improve the prior authorization (PA) experience for both providers and members, we are implementing significant updates to our PA requirements1. These changes align with industry-wide modernization initiatives and commitments to regulatory agencies and AHIP, striving to make prior authorization more efficient and transparent.
What’s changing?
Starting December 1, 2025, updated PA code requirements will take effect, as detailed in the table below.
Key changes include:
- Removal of certain PA requirements based on clinical necessity and review urgency.
- Standardization of PA requirements across lines of businesses to reduce confusion and support future real-time authorization capabilities.
Our objectives:
- Reduce administrative burden.
- Simplify submission and approval processes.
- Support timely access to high-quality, medically necessary care.
