Village officials have blocked the local ambulance company from billing residents for service, three months after an explosive debate on the practice.

A few residents argued during a Port Jefferson Village Board of Trustees meeting in November that it was unfair, after paying ambulance district taxes, they received bills for ambulance rides when their insurance companies either denied a claim or left them with a hefty deductible to pay. But the board insisted such bills were not the intention of the plan enacted several years ago to help their emergency medical organization recoup expenses.

Faced with rising costs in the ambulance district — which includes Port Jefferson, Belle Terre and Mount Sinai — the board authorized the Port Jefferson Volunteer Ambulance Company to bill patients’ insurance companies for service within their jurisdiction, using the collected funds to offset ambulance taxes.

The bills being sent later on to patients, according to PJVAC Deputy Chief Rob Stoessel, originated because his group and its third-party billing company are obligated to ask for the balance if the insurance does not cover the entire cost. In November he described the requirement as a “good faith attempt.”

Before insurance, the fee on a call for emergency medical care is $900, with an additional $18 for each mile the ambulance transports a patient. Stoessel said that amount takes into consideration both medical and nonmedical expenses like gasoline.

Both he and Mayor Margot Garant agreed that when the billing program was created, the idea was for patients to receive three notices for bills, with no consequences for not paying — as the ambulance company does not have a mechanism for collections.

“The insurance companies, God bless them — collect every nickel from them,” Garant said in November. But “we didn’t want the resident to be pursued for any of the fees.”

Residents who received the bills complained that wasn’t common knowledge, and they were concerned about their credit ratings.

Monica Williams was denied Medicare coverage for her treatment.

“I don’t really think that any village resident … should be looking at a bill like that,” Williams said in November. “It’s surprising. It’s disappointing.”

She called it “being billed for the same thing twice.”

But Williams saw a solution on Monday night, when the Board of Trustees voted to ban the ambulance company from billing residents.

The previous law that allowed the company “to bill, directly, village residents for the use of its ambulance services … is hereby rescinded,” according to the measure members approved at their meeting. It also forgives all unpaid balances currently hanging against residents.

PJVAC will still be able to collect funds from the insurance companies.

Garant said there would be consequences “if we hear of any resident getting any more collection documents from the ambulance [district].”
