Medical Billing - "Transparent" Charges; Is This Possible?

As I have mentioned, previously, a DRASTIC change to our health care system, LIKE Socialized Medicine, makes me nervous as a Medical Biller. I feel that this type of change would put my job in jeopardy.
I did, however, see a news segment recently that spoke about "Transparency" in insurance billing and payouts, according to specialty and whether the services received by the patient were done so at a hospital, clinic or private practice.
This seems like an interesting idea and I'll explain why.
The current system varies to extremes.
I have TWO Physical Therapy clients. Each submits an identical code. One of my clients receives a reimbursement of $69.27, while the other - for the exact same code - receives $16.38! What is with these numbers?? There is no rhyme or reason and getting a valid explanation from a payer is next to near impossible.
It's almost as if the representatives employed at these carriers are unable to explain such vast differences in payouts also.

In a revised "Transparent" health care system, all providers within a specialty would be reimbursed at the exact same rate, regardless of history or longevity, or which size the moon was at the time while credentialing with the carrier.
There would be SOME variation depending upon the location of the services; hospital, clinic or private practice. But, Medicare would need to impose such a regulation in order for all carriers to follow suit.
Asking Medicare for a change to this magnitude is like asking the sun to quiet its rays for a while; impossible!

However, the only organization that could force Medicare to oblige would be the government, somewhat, unfortunately...
SICKO and Michael Moore are, of course, considered fiercely liberal.
What this movie has done though, is forced a dialogue to occur regardless of one's position in the political spectrum. A republican from Iowa - Charles Grassley -is the individual that coined "Transparency".
Many advocates for change in our health care system see this point of view as the closest to the best outcome for all to date.
What do you think??
