Type 6 HIPAA Line of Service Testing
Type 6 validation is used to ensure that HIPAA transaction data for claims meets specific requirements that are related to specialized healthcare service, or products such as medically related transport, durable medical equipment, or chiropractic treatment.
For example, the Situational Rule for the Ambulance Transport Information (CR1 Segment in the Claim Information (2300) Loop of the Health Care Claim: Professional (X222A1 -837)) transaction set states that the segment is "Required on all claims involving ambulance transport services."
