A bill aimed at stopping an Upper East Side pharmacy from fleecing 9/11 responders by charging them $150 for a simple printout of records is in the works.

Assemblyman Richard Gottfried, chairman of the health committee, will introduce an amendment to “close a gap in state law” that requires medical facilities to provide copies of medical records at minimal copying cost, but does not mention pharmacies.

Gottfried announced a measure to include drugstores after The Post reported that Madison Avenue Pharmacy was demanding $150 for a couple of pages of prescription records.

“No one should have to pay anything like $150,”Gottfried said.

The pharmacy backed down, saying “Our policy going forward will be to process all Victim Compensation Fund claims free of charge.”
