2025 Best In KLAS CMS Payer Interoperability

Cognizant has long been a major player in payer technology, with offerings that span core administration, care management, quality/reporting, and pricing/payment analytics, along with a range of consulting and business processing services. Some health plans use a single solution from Cognizant, but others are deep adopters: i.e., long-standing clients that leverage multiple Cognizant offerings across their organizations. For this report, KLAS spoke with six vendor-identified deep adopters to learn (1) how they are using Cognizant’s offerings, (2) what their experience has been with the vendor, and (3) what benefits they have realized from their deep adoption.

White Paper

Consistent High Performers 2025

07 November 25 | Bradley Hunter and Lance Merrell

KLAS’ reports—including the annual Best in KLAS report—share which software vendors and services firms excel in helping healthcare professionals improve various aspects of healthcare. While reports typically draw from data collected over the prior 12 or 18 months, we wanted to examine which companies deliver strong client satisfaction over a longer period of time. To answer this, KLAS is introducing the Consistent High Performers report, a new annual report recognizing vendors and services firms that maintain high client satisfaction on a three-year rolling basis for a specific offering. This inaugural report—intended to complement Best in KLAS—identifies the 2025 consistent high performers and how they are collectively rated across KLAS’ customer experience pillars. Additionally, the report draws from surveys administered to 25 consistent high performers, who shared similar best practices for maintaining high client satisfaction. KLAS hopes this report helps healthcare organizations identify future partners and prompts other HIT vendors and firms to implement these best practices.

Prior authorizations for referrals and clinical procedures are widely acknowledged as a significant pain point for all involved parties—payers, providers, and patients. Using implementation guides from HL7’s Da Vinci Project, the collaborators in this case study created bidirectional data exchange through a FHIR API that enables an automated, in-workflow authorization process. The pilot use cases have been successful, achieving improved efficiency, reduced costs, and—most critically—more timely care and improved patient outcomes.
