Obtaining a Property & Casualty Claim Number


The Property and Casualty Claim Number is required for electronic medical bills that are associated to State Farm® Property and Casualty lines of coverage, except for a handful of Worker's Compensation Jurisdictions which allow the value of "UNKNOWN" if the P&C Claim Number is unavailable.

To obtain the Property and Casualty Claim Number for Worker’s Compensation, you can contact the patient, the patient’s State Farm claim representative, or patient's employer.

To obtain the Property and Casualty Claim Number for Auto, you can contact the patient or call the patient’s State Farm claim representative.


Submitting the Property & Casualty Claim Number in an Electronic Health Care Claim Transaction

For State Farm, the data length of a claim number is typically 9 characters (some claim numbers prior to a 1990 Date of Loss may be 6 numeric characters and if a policy state has not been assigned to the claim yet then the claim number could be 7 characters). Positions 1 and 2 of a 9 character claim number will always be numeric.  Position 3-9 of the 9 character claim number may be either numeric or alphabetic. Example:  99A123456

In an electronic health care claim transaction, the P&C Claim Number is required to be mapped to the Property and Casualty Claim Number REF segment using the reference qualifier of Y4 at either the Subscriber Loop (2010BA) or at the Patient loop (2010CA). For Worker's Compensation bills, the P&C Claim Number should be mapped to the Patient Loop Property and Casualty Claim Number REF segment unless the employer is not known at the time of the billing.  If the employer is not known, then the P&C Claim Number can be mapped to the Subscriber Loop Property and Casualty Claim Number REF segment. For Auto bills, the P&C Claim Number can be mapped to the either the Subscriber or Patient Loop Property and Casualty Claim Number REF segment.

To ensure the P&C Claim Number is being mapped properly from your billing software application to an electronic health care claim transaction, you will need to check with your billing software vendor to determine where to key the P&C Claim Number so that it is mapped to the proper location in the electronic health care claim transaction. On paper CMS1500 billing forms submitted to State Farm, the P&C Claim Number is often being placed in the Box 1a location. However, since this is the location where the Health Care Member ID is also located and most billing software applications map this to the Subscriber Primary ID element in the electronic health care claim transaction, then it is critical the P&C Claim Number be entered on the CMS 1500 form or equivalent billing software in a location that will also map the claim number to the P&C Claim Number element in the electronic health care claim transaction.  Some billing software applications are mapping the P&C Claim Number from Box 11b. If this is the case, then you could also continue to key the P&C Claim Number in Box 1a or the equivalent location in your billing software since Box 1a also maps to a required element within the electronic health care claim transaction.

Box 1a – Enter the P&C Claim Number unless you have been instructed by your billing software vendor to place in Box 11b.

Box 11b – Enter the P&C Claim Number in this location in addition to Box 1a unless you have been instructed by your billing software vendor to only place in Box 11b or only in Box 1a.
