Hi Everyone,
It's been a long time since I've needed to check in, but here is a question I have. I have been billing for an LICSW (Massachusetts), I have used an HO modifier in the past when needed, but Optum, just refused a claim saying I was using the wrong modifier. I thought HO was the correct modifier, can anyone tell me if this is correct? If not, can you tell me which modifier I should use. This if for an individual session 90834 outpatient mental health.
Thanks in advance,
Karen
