Eh actually I'm not sure lah pasal aturan dia, tapi a few of us tried continuity of care macam tu and it depends je on your medical records lah, kalau properly transferred, usually okay je, tapi lepas tu kena inform dulu HSA pasal plan nak deliver kat HSI so they update file you. Better email or call HSA clinic kat JB directly to confirm, sebab ada hospitals yang strict pasal referral letter and record handover, takut nanti masa deliver ada problem je with incomplete history. Kak, mula-mula inform aje, jangan sampai tunggu last minute!
