PayerList Outages

The PayerList /outages endpoint enables providers comprehensive real-time visibility into payer product outages using the stand-inReason indicator as the primary identification mechanism. The API serves as a critical operational tool for monitoring and managing product availability across healthcare systems, enabling proactive outage management and system reliability.

The API enables operational teams to:

Providers can identify active product outages using the stand-inReason indicator flag
Providers can search for payer IDs for PayerId and AdditionalSupportedIDs
Monitor outage status across multiple healthcare systems (IMN, IEDI, EXCH, DENTAL, RPA), transaction type, and payer configuration
Provides providers can use multiple comma separated
- Filter values function as an OR for: transactionType, system, imnPayerId, and standinReason
Support incident response with detailed outage information and affected product details
- This service is essential for maintaining service reliability and ensuring transparent communication about product availability issues.
Filters outage fields
- Payer Outage API by multiple values on certain fields, such as TransactionType, so that I can get a clear picture of outages with a single search
Response includes the issueStartDate
Exports outage data as CSV

Outage Identification Fields

Primary Outage Indicators (Essential for Outage Detection)

Field	JSON Tag	Value	Outage Purpose
`payerProductStandinFlag`	`payer_product_standin_flag`	Y/N (Yes/No)	PRIMARY: Indicates product outage status
`system`	`system`	IMN, IEDI, EXCH, DENTAL, RPA	CRITICAL: Outage scope identification
`active`	`active`	Y/N (Yes/No)	ESSENTIAL: Service availability
`payerName`	`payer_name`	String	IMPORTANT: Human-readable outage identification
`transactionType`	`transaction_type`	837P, 837I, ELIGIBILITY	IMPORTANT: Affected service type

Notes and validation rules

system is REQUIRED — every request must include it.
Date fields strictly require YYYY-MM-DD format; datetime strings are rejected.
startDateTimeBefore must be equal to or after startDateTimeAfter.
transactionType and sort support both repeated params (&transactionType;=A&transactionType;=B) and comma-separated strings (&transactionType;=A,B).
The same multi-value behavior applies to imnPayerId and standinReason.
wildcardSearch defaults to Yes — substring matching is active unless explicitly set to No.
The /outages/export endpoint accepts the same parameters and returns a CSV file.
