The lawyer, John Rivas, said the doctor acknowledged an "error" in the diabetes diagnosis for ABC News' undercover grandmother on the patient referral form but said, "this section was filled out by someone other than Dr. Bhadriraju," even though he confirmed the doctor did fill out the majority of the form and signed it in her handwriting.
Her signature served as certification that "my clinical findings support that this patient is homebound."
The doctor's lawyer said neither the doctor nor others in her office knew who filled in the incorrect diabetes diagnosis.
Rivas also said the doctor played no role in the official certification form sent to Medicare, although records show she billed Medicare for the review of the form and its plan of care.
"The records provided by ABC News do not support any allegations of fraud. It would be irresponsible journalism to air a story on Medicare/Medicaid fraud using this referral as an example when there is clearly no evidence of fraud," he added in a letter to ABC News.
ABC News ended the undercover investigation before any medical supplies or equipment could be billed to Medicare based on the false diagnosis.
