I believe the deductible only applies to the property coverage and not the liability or medical payments coverages.
Out of curiosity I called our renter's insurance carrier and asked them what it would cost to increase our medical payments from $1,000 to $5,000 (their maximum for med pay). They said it would make no difference to the minimum premium we currently pay, so I asked them to increase the med pay limit. I think the cost to increase med pay would be pretty modest even if it didn't fall within the policy minimum.
