# Claim edit: ICD-9 qualifier after the ICD-10 transition date > Stedi now rejects 837P professional and 837I institutional claims that declare ICD-9 for a service provided on or after October 1, 2015. Published Sep 4, 2026 Product: Claim edits Stedi now rejects [837P professional](https://www.stedi.com/docs/healthcare/submit-professional-claims) and [837I institutional](https://www.stedi.com/docs/healthcare/submit-institutional-claims) claims that declare ICD-9 for a service provided on or after October 1, 2015. ## ICD-9 qualifiers and service dates On October 1, 2015, the U.S. healthcare system replaced ICD-9 with ICD-10. Both the diagnosis code sets and the inpatient procedure code sets changed on that date. A payer won't accept a claim that declares ICD-9 for a service on or after that date. A claim declares its code set with a code list qualifier. The qualifier sits in a Health Care Code Information (`HI`) segment in Loop `2300`, and it introduces the code that follows it. Each `HI` segment holds up to 12 composites, so a qualifier can also appear in `HI02-1` through `HI12-1`. **Clinical Modification (CM) diagnosis qualifiers in 837P professional claims** | **ICD-9 qualifier** | **ICD-10 qualifier** | **JSON API field** | **X12 element** | | -------------------------- | -------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------- | | `BK` (principal diagnosis) | `ABK` | [`claimInformation.healthCareCodeInformation[].diagnosisTypeCode`](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-claims#body.claimInformation.healthCareCodeInformation) | `HI01-1` (Code List Qualifier Code) of the Health Care Diagnosis Code `HI` segment in Loop `2300` | | `BF` (other diagnosis) | `ABF` | [`claimInformation.healthCareCodeInformation[].diagnosisTypeCode`](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-claims#body.claimInformation.healthCareCodeInformation) | `HI01-1` (Code List Qualifier Code) of the Health Care Diagnosis Code `HI` segment in Loop `2300` | **Clinical Modification (CM) diagnosis qualifiers in 837I institutional claims** | **ICD-9 qualifier** | **ICD-10 qualifier** | **JSON API field** | **X12 element** | | --------------------------------- | -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | -------------------------------------------------------------------------------------------------- | | `BK` (principal diagnosis) | `ABK` | [`claimInformation.principalDiagnosis.qualifierCode`](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-institutional-claims#body.claimInformation.principalDiagnosis) | `HI01-1` (Code List Qualifier Code) of the Principal Diagnosis `HI` segment in Loop `2300` | | `BF` (other diagnosis) | `ABF` | [`claimInformation.otherDiagnosisInformationList[][].qualifierCode`](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-institutional-claims#body.claimInformation.otherDiagnosisInformationList) | `HI01-1` (Code List Qualifier Code) of the Other Diagnosis Information `HI` segment in Loop `2300` | | `BJ` (admitting diagnosis) | `ABJ` | [`claimInformation.admittingDiagnosis.qualifierCode`](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-institutional-claims#body.claimInformation.admittingDiagnosis) | `HI01-1` (Code List Qualifier Code) of the Admitting Diagnosis `HI` segment in Loop `2300` | | `BN` (external cause of injury) | `ABN` | [`claimInformation.externalCauseOfInjuries[].qualifierCode`](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-institutional-claims#body.claimInformation.externalCauseOfInjuries) | `HI01-1` (Code List Qualifier Code) of the External Cause of Injury `HI` segment in Loop `2300` | | `PR` (patient's reason for visit) | `APR` | [`claimInformation.patientReasonForVisits[].qualifierCode`](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-institutional-claims#body.claimInformation.patientReasonForVisits) | `HI01-1` (Code List Qualifier Code) of the Patient's Reason For Visit `HI` segment in Loop `2300` | **Procedure Coding System (PCS) qualifiers in 837I institutional claims** | **ICD-9 qualifier** | **ICD-10 qualifier** | **JSON API field** | **X12 element** | | -------------------------- | -------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------ | | `BR` (principal procedure) | `BBR` | [`claimInformation.principalProcedureInformation.qualifierCode`](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-institutional-claims#body.claimInformation.principalProcedureInformation) | `HI01-1` (Code List Qualifier Code) of the Principal Procedure Information `HI` segment in Loop `2300` | | `BQ` (other procedure) | `BBQ` | [`claimInformation.otherProcedureInformationList[][].qualifierCode`](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-institutional-claims#body.claimInformation.otherProcedureInformationList) | `HI01-1` (Code List Qualifier Code) of the Other Procedure Information `HI` segment in Loop `2300` | The edit compares the qualifier against a governing date. A date of injury governs when the claim carries one. ICD-9 stays valid for an injury that predates the transition, even when the services came later. Otherwise each service line's own date of service governs. **Date of service** | **Claim type** | **JSON API field** | **X12 element** | | ------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------- | | 837P professional | [`claimInformation.serviceLines[].serviceDate`](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-claims#body.claimInformation.serviceLines.serviceDate) | `DTP-03` (Date Time Period) of Loop `2400` (Service Line) with qualifier `472` (Service) | | 837I institutional | [`claimInformation.serviceLines[].serviceDate`](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-institutional-claims#body.claimInformation.serviceLines.serviceDate) | `DTP-03` (Date Time Period) of Loop `2400` (Service Line) with qualifier `472` (Service) | **Date of injury** | **Claim type** | **JSON API field** | **X12 element** | | ------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------- | | 837P professional | [`claimInformation.claimDateInformation.accidentDate`](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-claims#body.claimInformation.claimDateInformation.accidentDate) | `DTP-03` (Date Time Period) of Loop `2300` (Claim Information) with qualifier `439` (Accident) | | 837I institutional | [`claimInformation.occurrenceInformationList[][]`](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-institutional-claims#body.claimInformation.occurrenceInformationList) with an accident occurrence code `01`-`06` | `HI` segment in Loop `2300` (Occurrence Information) with qualifier `BH` | A service date is required on every 837P service line. On an 837I claim it's optional, so the edit falls back to the claim statement date in [`claimInformation.claimDateInformation.statementEndDate`](https://www.stedi.com/docs/healthcare/api-reference/post-healthcare-institutional-claims#body.claimInformation.claimDateInformation.statementEndDate) (`DTP-03` of Loop `2300` with qualifier `434`). ## How the edit works If a claim uses an ICD-9 qualifier and a governing date falls on or after October 1, 2015, the payer may reject the claim. 837D dental claims don't carry ICD-9 qualifiers, so this edit doesn't apply to them. This [edit](https://www.stedi.com/docs/healthcare/claim-edits-and-repairs#edits) catches the issue before the claim reaches the payer. It prevents payer rejections, which take longer to resolve and delay payment for the provider. ## Rejection errors If you submit a claim using Stedi's [Claim Submission API endpoints](https://www.stedi.com/docs/healthcare/intro-to-claim-submission#api-claim-submission) and the claim fails the edit, you'll get back an error response in real time. The response includes details in the `errors` array. ```json { "errors": [ { "code": "33", "description": "Invalid ICD-9 Qualifier usage. A code list qualifier indicating ICD-9 can not be used for service dates after 09-30-2015. Submitted qualifier(s): BK. Correct and resubmit.", "followupAction": "Please Correct and Resubmit" } ] } ``` The error names every distinct ICD-9 qualifier on the claim. If you submit a claim using [SFTP](https://www.stedi.com/docs/healthcare/submit-claims-sftp-connection) and the claim fails the edit, Stedi will reject the claim with a [277CA claim acknowledgment](https://www.stedi.com/docs/healthcare/claim-responses-overview#277ca-claim-acknowledgment). The acknowledgment will include a related [claim status category code](https://x12.org/codes/claim-status-category-codes), [claim status code](https://x12.org/codes/claim-status-codes), and error message. ```text STC*A7>508*[DATE]*U*[AMOUNT]******A7>488**Invalid ICD-9 Qualifier usage. A code list qualifier indicating ICD-9 can not be used for service dates after 09-30-2015. Submitted qualifier(s): BK. Correct and resubmit.~ ``` ## Resolution tips This edit checks the qualifier. It doesn't check the code the qualifier introduces. To resolve a rejection, change the qualifier to its ICD-10 counterpart, change the code to an ICD-10 code, or change both. ## Related claim edits Stedi has a mirror edit for the opposite mismatch, an ICD-10 code paired with a service date before the transition.
