I heard from my colleague his baby kena RM1000 over for 2 days photo-therapy in a private hospital in Penang a few months back.
If you have budget constraint, you might want to consider renting a phototherapy system at home. Google it and you should find businesses offering this. But make sure you notify your medical care provider.

I remember pediatrician always encourage newborn to feed frequently to alleviate jaundice when my sons were born few years back. I paid a few hundred ringgits back then for phototherapy as we got tired of frequent trips to Klinik Kesihatan.
