Ay sis, PhilHealth forms talaga ang hassle lalo na pag maraming agencies involved! Based sa situation mo, I think you need to submit to the current/new company since that's where your hubby is officially employed now, pero you might also need a certification from the previous agency showing na updated na sila sa final contributions para wala conflict sa MDR, a few of us had similar setup and ang HR ng bagong company usually knows the process na. Since hubby is at sea, pwede mo ring i-coordinate directly with PhilHealth mismo (punta ka sa office or call their hotline) para clarify kung kailangan nyo ng both agencies' signatures or just the current one, kasi ang email reply ay talaga sometimes slow talaga. Goodluck mama, and congrats on your December baby!
