TYLER (AP) — Some medical workers responsible for treatment billing codes say they felt pressured by a Dallas-area doctor to allegedly falsify data to get more money from Medicare.

Testimony continues in the Tyler health care fraud trial of Dr. Tariq Mahmood, who's denied wrongdoing.

Federal prosecutors say the hospital chain owner conspired to submit more than $1.1 million in false billings.

The Dallas Morning News ( reports Norma Longley testified Monday that she balked at changing billing codes for Renaissance Hospital Terrell patients.

Longley says Mahmood insisted diagnoses by other doctors be altered to reflect more expensive treatments. She later discovered her codes for Medicare reimbursements were altered.

Cynthia Kennemer Plumlee testified she was fired after refusing to let Mahmood be "involved" in reviewing patient. She cited professional ethics.
