I am getting conflicting answers of billing for place of service 33, what i read is that block 32 on cms 1500 can remain blank for place of service 33 (custodial care/personal care home. I am searching for mln matters articles/etc to confirm as i have also read that block 32 needs to be completed with NPI for services provided in place of service other than home or office-but personal care home 33 doesn’t have NPI as they are not a health care provider. any input would be appreciated.
