^^^^ This. All of this. PLUS THIS:
You have now admitted in an open forum to committing Medicare fraud. You cannot bill Medicare MORE than you bill anyone else. You must bill Medicare your actual fee, and they pay either 80% of that or 80% of their fee schedule, whichever is lower.
Example:
You bill $500 for a 99215. Medicare allows $150 and pays $120; $30 is the coinsurance/copay to the patient.
You bill Medicaid $75 for 99215 because that's what Medicaid allows.
Your actual fee is $75, not $500. Now Medicare comes back and does an audit. 80% of $75 is $60, which is what Medicare should have paid, not $120. You now have to pay back $60 ($120-$60) for every 99215 you billed Medicare over the last five (?) years. Are you prepared to do that??? Now multiply that out by every CPT code you bill.
Don't think Medicare won't find out. They will.
This is bad. Very Bad. VERY, VERY BAD.
