It looks like a coding error
A0427 keyed instead of A0428 A0428 more closely matches the trip record.
Thanks for your consideration. BTW, I live in Ventura County and the incident was in Santa Barbara County.
Vitals
Blood Pressure, pulse rate, probably respiratory rate, and temperature. Pardon me for saying, but it was the usual basic admitting nurse triage routine without a history.
Thanks for your additional question.
Opinions please:
I was the patient for a short trip to the local ER. The ambulance company tried to bill Medicare but was denied because I do not have Medicare yet. The company then tried to bill Anthem Blue Cross for A0427, but was denied. The care level during the trip was basic vitals...
