Heart doc, 94, collecting and working

We should all be as disabled as this 94-year-old retired city employee — he’s enjoyed a cushy tax-free pension for more than two decades and has still worked for the city on the side.

Former NYPD chief cardiologist Dr. Irving Kroop retired in 1986 — when he was 70 — with a $64,364 disability pension awarded because of a bad heart, according to sources and city records.

All the while, he’s maintained a private practice in Brooklyn and moonlighted at NYCERS, the New York City Employees Retirement System, which paid him $14,479 last year to help determine whether other city workers should get disability pensions.

“Hats off to the man — he’s 94 years old but disabled? And still going strong?” said an incredulous Carol Kellerman, head of the Citizens Budget Commission.

Kroop, who gets $155 an hour as a private contractor for city’s civilian pension board, shuffles into examining rooms with a cane and oxygen tank, sources say.

Kroop was on vacation last week and unavailable for comment.

The city’s pension costs are expected to reach $7.6 billion this year and hit $8.7 billion next year.
