Its Duckworth Billing. They are a medical billing service.

Call came in on 2/17/17 @ 8:34 a.m. Caller ID on land line showed McKesson Advance was calling to confirm our address.  Woman had a Texan accent and said she was a billing service for a hosp we frequent (gave correct hosp. name).  Said my husb. had a procedure @ said hosp - gave correct date.  But,. gave wrong extremity (radiology dept) and wrong doctor name.  Just needed to confirm our address. I didn't feel comfortable w/ giving her info.  We receive daily scam calls - all day long.
