How Many Days Do You Usually Have An Ultrasound Reference Letter?
Sorry, I usually ask for the ultrasound referral letter today
What is your referral letter using? if you mean that the USG reference letter uses BPJS, then the letter is usually valid for up to 1 month. So you can still use the letter 1 month from the date the letter was issued.
However, if you use a referral with a particular insurance guarantee, then it can be different. Therefore, to be sure, you should ask directly to your health facility, so you can get more accurate information.
