LOS ANGELES (AP) _ Television director and producer Richard Irving, whose credits included ''Columbo'' and the ''Six Million Dollar Man,'' has died at the age of 73.

Irving died Sunday after heart surgery at an undisclosed San Diego hospital, and was buried Wednesday following a funeral at Hillside Memorial Park in Los Angeles, according to the mortuary.

Irving, a onetime Broadway and film actor, was a dialogue director at the RKO film studio before entering television. Later he helped establish Revue Productions, the MCA Universal television production subsidiary.

He oversaw the production of 36 TV films during one six-month period in 1971. In 1949 and 1950, he produced 22 episodes of the 90-minute ''Mystery Theatre'' features.

Irving produced the Gruen and Chevron Theater anthologies, ''Pepsi-Cola Playhouse,'' ''Name of the Game,'' ''Columbo,'' and ''Wagon Train.''

He also directed the pilot film for ABC-TV's ''Six Million Dollar Man'' and the NBC-TV miniseries ''Seventh Avenue.''

He was executive vice president of Universal TV until 1979. Shortly after his departure, he directed the mini-series ''The Jesse Owens Story.''

Most recently, Irving directed the ABC series ''The Insiders'' and NBC's ''Hell Town,'' and produced the TV movie ''The Last Days of Pompeii.''

Irving is survived by his wife, Joanne; a daughter, a son, three stepchildren and seven grandchildren.
