OS X partition corrupted after bootcamp use

Question

Starting with OS 10.10 and Windows 8.1, whenever I use Windows 8.1 for a variable amount of time, the OS X partition becomes corrupted.  Sometimes it is okay, but more often then not, when I leave bootcamp and boot back to OS X, the OS X partition won't boot.  Using Disk Utility (via Cmd-R) shows that the OS X partition is damaged and cannot be repaired.  I then have to format the partition and restore from a Time Machine backup.
The system is a MacBook Pro 10,1 (Retina Mid 2012).  There are no bizarre NTFS utilities installed, only a stock Windows 8.1 OS and OS X 10.10.2.  There are a handful of apps installed under Windows - AutoCAD, etc., but again, no file
Any suggestions?
Per LonerT, I am posting the output from diskutil.

Everything appears to be normal.  I have no idea why this happens on this machine.  My only other thought is that this machine was upgraded from 10.9.  My last option is to wipe the machine, install 10.10 from scratch, then reinstall everything again.  I dread this last option - it is usually the sign of a desperate individual (which I am).
