A system includes a memory device and a processing device, operatively coupled with the memory device, to perform operations including receiving a command to perform a program operation on a block of the memory device; determining whether the block is on an exclusion list; determining, in response to determining that the block is not on the exclusion list, whether a value of a media endurance metric of the block satisfies a media endurance metric criterion; performing, in response to determining that the value of the media endurance metric of the block satisfies the media endurance metric criterion, the program operation on the block; determining whether a media health metric of the block satisfies a health threshold criterion; and adding, in response to determining that the media health metric of the block satisfies the health threshold criterion, the block to the exclusion list.
