Using sed to replace specific character and specific position

I am trying to use sed to replace specific characters at a specific position in the file with a different value... can this be done?

Example:

File:
A0199999123
A0199999124
A0199999125

Need to replace 99999 in positions 3-7 with 88888.

Any help is appreciated.
