PatientIndexer

PatientIndexer matches an e-billing patient to a WCIS claim in ClaimCenter and validates the resulting claim state, implementing operation OP-DOM-02: it validates the claim number format, calls the Guidewire ICCClaimApiService to fetch the claim, compares worker and patient birth dates, sets the e-bill's ClaimId, and checks the indexed claim for void/draft status and non-complying-employer flags. All errors are reported through the supplied IErrorConditionHandler rather than thrown, except for a wrapping exception at the batch level.

Purpose

• Validates that a patient's claim number is present and correctly formatted before attempting to index it, rejecting "UNKNOWN" and any number outside the 7–8 character rule (DOM-BR-010, DOM-BR-011).
• Retrieves the claim from ClaimCenter and records specific error conditions for an API failure or a missing claim, so callers can distinguish "claim service unavailable" from "claim does not exist" (DOM-BR-012, DOM-BR-013).
• Confirms the worker's and patient's birth dates match before setting the e-bill's ClaimId, and flags void/draft claim status and non-complying-employer claims once indexed (DOM-BR-014, DOM-BR-015, DOM-BR-016).

Context

• Namespace: SAIF.Domain.Claims.Ebilling.Indexing
• Assembly/package: SAIF.Domain (Domain/SAIF.Domain/SAIF.Domain.csproj, .NET Framework 4.6.2 class library)

Public members

Member	Signature	Purpose
IndexPatientsToClaim	public static ResultCount IndexPatientsToClaim(long batchId, IEbillingQueryProvider queryProvider, IErrorConditionHandler errorConditionHandler, string updateUser, ICCClaimApiService ccclaimApiService)	Indexes every non-indexed patient on the batch to its claim, tallying successes/failures into a ResultCount and rethrowing any per-patient exception with the patient id attached.
IndexPatientToClaim	public static bool IndexPatientToClaim(EbillPatient patient, IEbillingQueryProvider queryProvider, IErrorConditionHandler errorConditionHandler, string updateUser, ICCClaimApiService ccclaimApiService)	Validates the patient's claim number, fetches the claim from ClaimCenter, confirms the birth dates match, sets ClaimId, and delegates to CheckIndexedPatientForClaimErrors for post-index validation (DOM-BR-010–DOM-BR-014).
CheckIndexedPatientForClaimErrors	public static bool CheckIndexedPatientForClaimErrors(EbillPatient patient, InjuryClaim claim, IErrorConditionHandler errorConditionHandler)	Flags an indexed claim as an error when its WCD status is void, its claim state is draft, or it is a non-complying-employer claim, recording each condition independently (DOM-BR-015, DOM-BR-016).

Behavioral notes

• The ClaimCenter lookup calls ICCClaimApiService.GetClaim synchronously via GetAwaiter().GetResult(), so a slow or failing call blocks the indexing loop for that patient*.
• IndexPatientToClaim returns false on every validation failure rather than throwing, so callers must check the return value (and the error condition recorded by IErrorConditionHandler) to detect a failed match.

Note: Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts.
