HCFA-1500 Box 11 - Insured's Policy Group or FECA Number

July 25, 2025
On the HCFA-1500 form, Box 11 is designated for the insured’s policy group or FECA number. This refers to the primary insurance policy number assigned to the patient by the payer, including group numbers or Federal Employees' Compensation Act (FECA) claim numbers.
Completing this box is required for claims involving group health insurance or FECA-related coverage. It ensures the payer can correctly identify the patient's insurance account and apply coverage appropriately.
Tip: Box 11 is required when billing a primary insurance payer. If the patient has no insurance, you may enter “None.” Do not leave this field blank unless directed.
In our example below, we populated Box 11 with the ID 'GP12345'.

So far, we've discussed how the insured’s policy or group number appears on the HCFA-1500 form. In this section, we’ll briefly explore how this information is represented in the X12 837 format.
In the X12 837 transaction, Box 11 maps to the SBR03
data element in the 2000B Subscriber Information Loop, specifically in the SBR (Subscriber Information) segment. SBR03
represents the insured’s group or policy number and is used to report the identifier assigned by the payer for the subscriber’s coverage.
The examples below illustrate how Box 11 maps to the 837 5010 and 4010 formats, specifically within the 2000B loop:
5010 Version:
SBR01
(Payer Responsibility Sequence Number Code): 'P' for Primary
SBR02
(Individual Relationship Code): '18' for Self
SBR03
(Subscriber Group or Policy Number): 'GP12345'
SBR09
(Claim Filing Indicator Code): 'CI' for Commercial Insurance Co.
4010 Version:
SBR01
(Payer Responsibility Sequence Number Code): 'P' for Primary
SBR02
(Individual Relationship Code): '18' for Self
SBR03
(Insured Group or Policy Number): 'GP12345'
SBR09
(Claim Filing Indicator Code): 'CI' for Commercial Insurance Co.
Sample 837P (5010) - 2000B - Subscriber Information
Sample 837P (4010) - 2000B - Subscriber Information
Note: HCFA Box 11 maps to SBR03
in the 2000B loop of the X12 837 for both 4010 and 5010 formats. This field is required when billing a primary insurance payer.
