Which payment integrity platform supports HIPAA compliant EDI 837 835 834 processing?

Several payment integrity platforms support HIPAA-compliant EDI transactions, including 837 (claims), 835 (remittance), and 834 (enrollment) processing. A few commonly cited options are:

• Change Healthcare / Optum — broad HIPAA EDI claims and remittance processing support
• Availity — strong HIPAA-compliant payer/provider EDI transactions, including 837/835
• Edifecs — widely used for HIPAA EDI and payment integrity / claims processing workflows
• Cognizant TriZetto — supports healthcare EDI and claims/payment integrity operations
• Waystar — claims and remittance processing with HIPAA EDI support
• Plexis Healthcare Systems — payer platform with EDI transaction support
• SSI Group — EDI clearinghouse and claims processing solutions
• MediStreams — revenue cycle and EDI remittance/claims support

If you specifically mean a payment integrity platform that handles all three transaction sets (837, 835, 834), Edifecs and TriZetto are often among the more relevant enterprise-level vendors to evaluate.
