As long as you are enrolled in a family HDHP (meaning your spouse has double coverage from Medicare and your HDHP) then you are allowed to contribute up to the family limit. Any other coverage your spouse has will disqualify her (she can't make her own $1000 catch-up, for example) but her other coverage does not disqualify you.
If you decided to downgrade your coverage to single (to reduce the premium since she is covered by Medicare) then you would be subject to the single limit going forward.
