Proof of service is the primary source documentation for a service or a result (not a secondary representation of the information), and should originate from the source system where it was first documented.
Acceptable proof of service:
- A copy of the information from the member’s chart from the service provider or PCP.
- A copy of the clinical report or clinical summary from the visit for service, such as lab or radiology reports.
- A screen shot of the EHR records or state- or county-sponsored immunization registry records.
Proof of service is primary source documentation, not a secondary representation of that information. The following provide examples that are not considered proof of service:
- C-CDA or FHIR files are electronically generated, and are not proof of service.Â
- Attestation forms are not the original source of documentation for an encounter, and are not proof of a service or result.Â
