Try this,

| makeresults 
| eval data="URI=/v4/cp/members/summary?hcid=AN5635356&firstnm=ELLEN&lastnm=BRODBINE&dob=1962-01-02" 
| rename data as _raw 
| rex field=_raw "hcid\=(?P<OUTPUT>[^\&]*)"

You need to escape special characters such as / and ?

Try URI=\/v4\/cp\/members\/summary\?hcid=(?P<hcid>[^&]+)

The value will be stored in field hcid
