This video is one segment in a series of videos from ResDAC’s Introduction to using Medicare Fee-for-Service (FFS) Data for Research.
The Carrier file contains claims submitted by non-institutional providers such as physicians, nurse practitioners, clinical laboratories, ambulance services, suppliers and stand-alone ambulatory surgical centers. The Outpatient file contains claims submitted by hospitals for non-inpatient care, including emergency room visits and other outpatient radiology and surgeries.
This presentation reviews specific variables useful for research files, examples include:
- dates of services
- services provided (HCPCS and modifiers)
- payment and charges for services
- the provider of services (NPI, Specialty codes)
The Carrier and Outpatient files contain some overlapping information, and this presentation clarifies the similarities and differences between the files.
