# How does Claim.MD decide when to update a claim record, or create a new one?

By default our system will identify a claim as an update to a previous record if all of these values match a previous claim:

- [pcn](https://docs.claim.md/v1/docs/professional-claim-form-overview#patients-account-number)
- [prov_npi](https://docs.claim.md/v1/docs/professional-claim-form-overview#rendering-provider-npi1)
- [prov_id](https://docs.claim.md/v1/docs/professional-claim-form-overview#rendering-provider-atypical-id)
- payer_order
- [proc_code (charge line field, 2400)](https://docs.claim.md/v1/docs/professional-claim-form-overview#procedure-code)
- [from_date (charge line field)](https://docs.claim.md/v1/docs/professional-claim-form-overview#date-of-service-from)
- [charge (charge line field)](https://docs.claim.md/v1/docs/professional-claim-form-overview#charge-amount)

Alternatively, if you are able to send a unique claim ID in the "remote_claimid" (REF*D9) field we can match that value exclusively.

That would mean you need to send the same ID each time you re-upload a claim to make sure the previous record is updated.

To request using the REF*D9 or remote_claimid value for updated claims in your account, open a support ticket and request the Duplicate Fields setting to be modified to "remote_claimid".
