MedicareService

Implements IMedicareService, the batch job that reconciles Medicare-beneficiary query results against the MedicareQueryHistory table for each submission batch, inserting new history entries and updating stale ones, then deleting the now-processed beneficiary batch. It depends on IUnitOfWork for persistence, IMedicareQueryProvider for reading beneficiary/batch data, and IUserProfileService to stamp history records with the current user. It accumulates run totals in an internally held MedicareHistoryResults instance created in the constructor and mutated across calls within a single service lifetime.

Purpose

• Processes the next available minimum-submission batch of Medicare beneficiary data: deletes the prior batch if it has already been fully reconciled, then inserts/updates history for the new batch.
• Determines whether a submission batch has been fully processed by comparing the beneficiary count against the matching history count for that submission date.
• Inserts new MedicareQueryHistory records for beneficiaries with no existing history match, and updates the LastSubmissionDate on records whose match is stale.
• Deletes the processed MedicareBeneficiaryQuery records and their batch marker once history has been reconciled.

Context

• Namespace: SAIF.Services.Claims.Medicare
• Assembly/package: SAIF.Services (packaged inside the SAIF.SAIFCode.Core NuGet package)

Public members

Member	Signature	Purpose
MedicareService	public MedicareService(IUnitOfWork uow, IUserProfileService prof, IMedicareQueryProvider qu)	Wires the unit-of-work, user-profile, and Medicare query-provider collaborators, and initializes the internal MedicareHistoryResults accumulator.
ProcessNextBatch	public MedicareHistoryResults ProcessNextBatch(ILogWriter controlReport)	Deletes the previous batch's beneficiary records if already reconciled, processes the next minimum-submission batch into history, throws if the post-processing counts still don't match, and returns the accumulated result totals.
HasPreviousBatchBeenProcessed	public bool HasPreviousBatchBeenProcessed(DateTime submissionDate)	Returns true only when the beneficiary count and history count for the given submission date are equal, indicating the batch has been fully reconciled.
ProcessMedicareBeneficiarysStatelessMode	public bool ProcessMedicareBeneficiarysStatelessMode(DateTime submissionDate)	Within a unit-of-work transaction, inserts history for beneficiaries with no existing match and updates the submission date on stale matches; always returns true.
InsertMedicareQueryHistory	public void InsertMedicareQueryHistory(MedicareBeneficiaryQuery medicareBeneficiary, string currentUser, DateTime submissionDate)	Creates and adds a new MedicareQueryHistory record copying the beneficiary's identity/response fields and stamping first/last submission dates and audit fields.
ProcessDeleteMedicareBeneficiarysForBatch	public bool ProcessDeleteMedicareBeneficiarysForBatch()	Within a unit-of-work transaction, deletes all beneficiary records for the current minimum-submission batch along with the batch marker itself; always returns true.

Behavioral notes

• ProcessNextBatch throws a generic Exception("Counts Don't match") if, after processing, the new batch is still not fully reconciled — a coarse-grained integrity check rather than a typed exception.*
• ProcessMedicareBeneficiarysStatelessMode and ProcessDeleteMedicareBeneficiarysForBatch each wrap their writes in IUnitOfWork.Begin()/Commit().
• Result counters (MedicareBeneRead, HistoryUpdated, HistoryInserted, MedicareBeneDeleted) accumulate on the single _historyResult instance created at construction, so a MedicareService instance is intended for one batch-processing run rather than reuse across independent runs.*
