Mapped - the final choice, the most suitable choice


Need to be found the best place for the field (not mapped currently)


Currently not important - not mapped

FHIR field

Description

STPH

Mapping status

PolicyID

PK

Identifier



Use only PolicyUUID

This is the Database ID and should be used only internally

PolicyUUID

UniqueIdentifier

Identifier

The unique identifier used as PK for FHIR

FamilyID

FK(tblFamilies)

policyHolder


We use the policyHolder to represent the reference to the Patient (head of the family). The insurance code is used to point the appropriate Patient.

Extension


The FHIR representation doesn't contain this type of value. If needed we can consider adding the FHIR extension.

PolicyStatus

tinyint

status

Default: 1
1 - Idle
2 - active
4 - suspended
8 - Expired

There are some differences between the Policy and FHIR statuses. List of FHIR coverage statuses:
1) active
2) cancelled
3) draft
4) entered-in-error

PolicyValue

decimal

contract.valuedItem.net


The FHIR representation doesn't contain this type of value. If needed we can consider adding the FHIR extension.

contract.valuedItem.net


ProdID

FK(tblProduct)

grouping


The FHIR representation doesn't contain exactly the same type of value. The coverage classifications can be contained in the "grouping" field and we can join it with a product using grouping.plan. See example: https://hl7.org/fhir/STU3/coverage-example.json.html

I would suggest to check Contract entity => Coverage.contract 


OfficerID

FK(tblOfficer)

contract.agent.actor


The FHIR representation doesn't contain this type of value. If needed we can consider adding the FHIR extension.

subscriber


PolicyStage

char(1)


Default: N
N - New Policy
R - Renewed Policy

The FHIR representation doesn't contain this type of value. If needed we can consider adding the FHIR extension.


Will be added after when the final approach will be established

ValidityFrom

Audit information. More information can be found here (on page 113):
https://github.com/openimis/openimis_docs/blob/master/specs/Web%20application%20-%20Functional%20Design%20Specification.pdf

This information are valuable for OpenIMIS but I probably not required by external systems.




Internal field


ValidityTo

datetime



LegacyID

int



AuditUserID

int



RowID

timestamp



I'm not sure but this is probably some unique value used to distinguish database rows. Probably not useful for external systems.

Internal field


isOffline

int



I'm not sure but this is probably used to determine the source of row (offline/online app). Probably information isn't valuable for external systems.
