Variable: CLAIM_ADJUSTMENT_GROUP_CODES

const CLAIM_ADJUSTMENT_GROUP_CODES: object

The 4 spec-fixed Claim Adjustment Group Codes. Frozen literal union via as const so consumers compare code === CLAIM_ADJUSTMENT_GROUP_CODES.PR and TypeScript narrows exhaustively.

• CO - Contractual Obligation. The provider's contracted write-off (e.g. payer fee schedule below billed charges). The PROVIDER eats this. Posting CO to patient responsibility is the wrong-party bug.
• PR - Patient Responsibility. Patient deductible / coinsurance / copay / non-covered. The PATIENT owes this. This is the patient-statement total.
• OA - Other Adjustment. Used when neither CO nor PR fits - typically prior-payer payments, COB adjustments, withholding for refund. Use is fact-pattern-specific.
• PI - Payer Initiated Reductions. Payer-side reduction the provider may not dispute under the contract - e.g. bundling edits, prepayment review reductions.
