Medical costs... Victoria vs. Houston

I have notice a trend in the billing submitted to Mutual of Omaha, plan f provider, since my mom broke her elbow and is still under care.

Two ER visits and a TWO day stay at Detar... Submitted $1750 for the two ER visits, annnndddd get this $60,448.08 for a TWO day hospital stay! The hospital stay charges where found in error, but Detar submitted them. Mom was transferred to Methodist in Houston, $270.00 a day.

The Doctors who visited her in her room at Detar... $250 to $395 a visit.
The Doctors who visited her in her room at Methodist, ( TMI Associates, Baylor College of Medicine, ect.), ... $103 to $250 a visit.

Victoria Orthopedic surgeon, who only cleaned out the infection she developed and did not set the chipped bone.... $1350.00
Houston Orthopedic surgeon, who set the chipped bone, grafted tissue and skin over infected area... $1840.00

Victoria anesthesiologist... $ 975.00
Houston anesthesiologist... $795.00

Does anyone not notice a higher fee charged in Victoria than Houston?
And in no way can you compare Detar to Methodist.
