Topic: Medicare beneficiary identifier identifier type
Lee Surprenant (May 18 2020 at 18:18):
https://www.hl7.org/fhir/identifier-registry.html lists Medicare Beneficiary Identifier http://hl7.org/fhir/sid/us-mbi with a Type of SB. However, in an internal mapping I just reviewed, I'm seeing the use of MC. Is one of these more right than the other? Are they both acceptable?

similarly, http://hl7.org/fhir/sid/us-ssn is listed with type SB where you might expect SS...which is right?

@Robert McClure any clue on this one? Any suggestions on who to ask?

I think that ssn should be a MB, but both us-medicare and us-mbi should be MC. Can you make a task to correct this please

opened FHIR#27538

Actually, I just realized that Identifier datatype has an extensible binding to https://www.hl7.org/fhir/valueset-identifier-type.html and that this valueset does not include MB, MC, or SS... so based on the definition of "Extensible", I think the recommendations on that Identifier registry are probably right.
Net: In FHIR, I guess we should favor SB over these older identifier types.

@Grahame Grieve Should SSN be MB? Social Security isn't an insurance program, so I would think SB would be more appropriate. For MBI and HICN (and Medicare identifiers in general), I think NIIP is the better region-agnostic code. MC is a case where regional (US/AU) terminology made it into the international tables. NIIP is really the general case of MC.

For non-national insurance, those IDs would be subscriber or member IDs on the Coverage (at least in the US), and putting those on patients is probably discouraged, unless maybe you are using Patient for a health plan member roster. On the health system, side putting (non-national) insurance identifiers on Patient gets confusing when you deal with the different insurance type that can apply. It looks like we don't have a code in the Identifier type value set for non-national insurance IDs, but since it is extensible... /shrug

Should SSN be MB
I think so, but it's #terminology where the correct answer would come from (the v2 experts)
