The FDNY has signed off on a more than 50% hike for basic ambulance rides.

The bump, from $900 to $1,385, or 54%, goes into effect May 1, according to city records.

It also raised the charge per mile for hospital trips to $20, up from $15.

Advanced life supports emergency transports would see smaller increases.

The fire department proposed the increase in February, citing inflation and increased salaries for EMS workers.

A few dozen New Yorkers weighed in on the change, calling the increase “unwarranted,” according to the public notice released Friday.

The FDNY countered the complaints, saying the increase would be covered by insurance and would help offset the burden of a round-the-clock 911 system.

The department also noted it offers programs to low-income people to help offset ambulance bills.
