Girum,
Yes, any uncompensated transfer by the CS (asset or income) will trigger a penalty period for the CS, should they need LTC within five years of the transfer. You are correct that the monthly MCA income will become an asset the following month. However, the CS must only stay under the CSRA in the month of application. Post application, the CS no longer needs to stay under the CSRA. Only the institutionalized spouse must continue to stay under their $2,000 asset limit to maintain asset eligibility.
Thanks,
Collin Terry
