Facing Allegations for Medical Billing Issues: How Should I Defend Myself in an Inquiry?

I had bought a few days' worth of medicine with a bill from the first shop in one state. However, after that, all my medical bills had to be processed at the second shop in a different state due to prescription date issues. Despite this, the purchases were still made from the first shop without a bill. Even though prescriptions from both shops were submitted, the batch number of the medicines remained the same on the bills. As a result, I am now under scrutiny by the vigilance department for:

1. Medical irregularities - batch number issue
2. Fraudulent medical claims
3. Malpractice
4. Misuse of medical facilities, CDA rule

Furthermore, the second shopkeeper provided a written statement to my company confirming that they only issued the bill, not the medicine.

In an official inquiry in front of the Inquiring Authority (IA), is there any defense against the above allegations possible? Should I accept, deny, partially accept, or plead guilty to all four charges considering the purchase was made, but there was a billing discrepancy?

Addressing Fraudulent Actions in Billing Issues

It may have been just a billing issue to you, but in reality, you are acting fraudulently. If you didn't get the bill, it is better to let go of the expense than to do something that may result in you losing your job.

Since the evidence is already there, you have no option but to admit to your actions, apologize, and promise never to do it again. In most cases, they will let it go, but if you are holding a position of confidence and trust, it is unlikely you will be able to retain your job.
