Karachi City Cricket Association president Sirajul Islam Bukhari confirmed Ahsan died early Friday in the city.
"Ahsan fought illness with courage," said Bukhari of Ahsan who was on dialysis for the last two years. "He served the game well and was particularly supportive of cricket in Karachi."
Ahsan played 12 Tests between 1958-62 and was a member of the Pakistan team on its first tour to the West Indies in 1858. He made his debut at Bridgetown where his old friend Hanif Mohammad scored 337 - still Pakistan's highest Test score.
Former Pakistan captain and legendary paceman Wasim Akram said it was Ahsan who selected him for the first time in 1984.
"As the chief selector, Ahsan convinced everyone of my talent and selected me against New Zealand," Wasim said. "He was very close to me and as a powerful selector, he spotted young talent and threw them in the bigger battles.
"I have lost a very close supporter and it's a great loss for Pakistan cricket," said Wasim.
Ahsan scored 61 runs and picked 27 wickets in his brief career, hit by bowling action controversy.
