The Standing Committee on Finance, headed by Congress MP Verappa Moily, had questioned Dr Patel once - on January 18 - on the move to ban high-value currency notes of Rs 500 and Rs 1,000 denominations.
"Patel has been asked to appear again before the panel on July 6 to brief the members about demonetisation as discussion on it is yet to be concluded," a member in the panel said.
The Committee had also called top finance ministry and Reserve Bank of India officials in January to discuss the impact of demonetisation.
Sources said that the members in the panel are likely to ask Dr Patel about how much money has come back into the system. The members will also enquire on when bank operations will be "normal".
