The Health Level 7 (HL7) FHIR is a new interoperability standard for exchanging healthcare data.

When mapping a drug from your local formulary to RxNorm, you may come across two different RxNorm drug concepts with the same ingredient, strength, form and route.

By now, you may have come across sex and gender being treated as two separate concepts, which sometimes results in confusion and overlap in how they are used to encode data in healthcare, especially if the two domains appear to share the same members (e.g., male and female in both value sets).
