He was too drunk to walk — but not to work.

A Brooklyn doctor who was falling-down drunk when he got busted by the feds in a massive insurance-fraud scheme says he would have been treating patients later in the day if not for his early-morning arrest.

“Who from Russia doesn’t drink? Everybody does,” an inebriated-looking Dr. Sergey Gabinsky said yesterday.

A prosecutor said Gabinsky, 54, “was so intoxicated he couldn’t walk” when he was nabbed Wednesday at 6 a.m.

And an hour later, testing revealed that the pediatrician had an “inordinately high” blood-alcohol level of 0.38 — nearly five times the legal limit for driving — prosecutor Nicholas McQuaid said during a bail hearing Wednesday evening.

Gabinsky was among three dozen people charged by Manhattan federal prosecutors in a $279 million-plus scheme to cheat insurance companies out of medical benefits under New York’s “no-fault” insurance law.

The record fraud, which involved more than 100 phony medical clinics across the city, was allegedly run by a ring of Russian crooks and a Long Island lawyer accused of advising them “on various aspects of their criminal activity.”

Gabinsky, who was sprung on a $250,000 bond, appeared blotto yesterday when The Post visited his posh apartment in Brighton Beach.

He walked with the help of a cane and his speech was slurred as he recounted the raid.

“They came at 6 o’clock in the morning. I couldn’t walk, so they took me to the hospital,” he said.

Gabinsky said he was taken to Long Island College Hospital, but maintained it was because he was suffering back pain.

“After that, they took me to the FBI building,” he said.

Asked if he drinks, Gabinsky admitted, “Sometimes, yes.”

“The court told me I have to do urine tests once a week,” he said.

After a sobering moment, he tried to retract his comments, insisting, “I don’t drive when I’m drunk. I don’t treat anybody when I’m drunk.

“I’m still a doctor. I don’t want you to put anything in the press,” he said.

“If somebody reads this article, you know what will be.”

The receptionist at Gabinsky’s office, which he shares with a physical therapist and a chiropractor, said that he generally handles his own schedule and frequently sees patients at New York Methodist Hospital.

She also said she had never known him to be drunk, and praised him as a physician.

A spokeswoman for New York Methodist said Gabinsky had been affiliated with the hospital since 1995, but wasn’t a paid staffer — and “nobody can remember seeing him recently.”

The spokeswoman, Lyn Hill, also said, “He’s going to be suspended.

“Depending on how the case is disposed, he will either be permanently severed from the staff or, if he’s found not guilty, he’ll be reinstated,” she said.

One of the alleged ringleaders of the scam, Mikhail Zemlyansky, 35, was expected to be released to house arrest today after his family posted a $2.5 million bond secured by $50,000 in cash yesterday.

Three other alleged ringleaders — Michael Danillovich, 38, Yuriy Zayonts, 40, and Mikhail Kremerman; 41 — didn’t ask for bail after being hauled into Manhattan federal court on Wednesday.
