The specific gamma ray dose constant for Cd-109 has been said to be
4.983e-05 mSv/hr per MBq at one meter.

My question is: Is this over 4 pi, or in 1cc of tissue?

I believe the answer would be "yes" and "yes."  As pointed out by Gary
Masters, the HP&RHH identifies the geometry under which the Specific
Gamma Ray Dose Constant is defined as "4 pi."  And, if memory serves
correctly, by definition, the Sv is defined as the dose "in tissue" at the
location of interest [not the full ICRP rendition, but close enough :~>].
