All I can find in 820.198 is: Each manufacturer shall establish and maintain procedures for receiving, reviewing, and evaluating complaints by a formally designated unit.
21 CFR 211.198.a states: Written procedures describing the handling of all written and oral complaints regarding a drug product shall be established and followed. Such procedures shall include provisions for review by the quality control unit, of any complaint involving the possible failure of a drug product to meet any of its specifications and, for such drug products, a determination as to the need for an investigation in accordance with § 211.192.
Mind you, 211 only requires that a quality organization review complaints in the event of possible failure of a drug product to meet any of its specifications, but does not require a formally designated unit to handle the complaints.
