meet US Core profile requirements when writing Patient and Condition resources

Steps

1. For US Core Patient: include at least one Patient.identifier with a system and value, Patient.name with family or given, Patient.gender (required), and Patient.birthDate (must-support); also include race and ethnicity extensions (us-core-race, us-core-ethnicity) if available.
2. Populate Patient.name.family and Patient.name.given as separate structured fields rather than only text; many systems require structured name components for matching.
3. For US Core Condition: set Condition.clinicalStatus (required binding to ConditionClinicalStatusCodes), Condition.verificationStatus (required), and Condition.category with at least one coding from the ConditionCategoryValueSet (e.g. 'encounter-diagnosis' or 'problem-list-item').
4. Condition.code must be present and should use SNOMED CT or ICD-10-CM; if using ICD-10-CM include the system http://hl7.org/fhir/sid/icd-10-cm.
5. Set Condition.subject to a reference to the Patient resource; include Condition.onsetDateTime or onsetPeriod when the onset date is known.
6. Validate both resources against the relevant US Core profile canonical URLs using $validate or the HL7 validator before submission.
