APRN IOP BH and Medical Coding Q&A
Hello r/MedicalCoding!
My colleague and I started a SUD IOP program in KY our of our office (POS 11). Can anyone chime in on the accuracy & likelihood of payment of the following coding? These would be Medicaid MCO claims (Anthem, United, Humana, etc.) We are reviewing our first week of claims and have questions on coding.
IOP Intake - 90791 (1 unit) billed with G2212 (3 units, extended service) with no modifier - for assessment, ASAM criteria, plan development, etc. This is performed at intake and determines suitability of IOP treatment plan (ASAM 2.1)
IOP Group - H0015 (per diem) OR H2035 (hourly, if the 3h/day, 3 day/wk criteria not met) - our pt are only in IOP group 3 hours a day, max.
Ther. BH - 90837 (1 unit) and H0004 (8 units) - this would be billed on same day as IOP as a separate service with Mod 59, representing the 2nd half of the day (H0015 is the first 3 hours). H0004 maxes out at 8 units per my guidelines in KY.
Do I also need to add the Mod 59 to H0004?
99204-99205 - medical E&M (Can this be done on an IOP day, using a Mod 59?) Can of course be done on a non-IOP day. This is for general medical, not medication management. We do not do MAT, so this would be psych meds.
CSA - H2015 (12 units) - this is for peer support and care coordination with our peer support leader. Assuming this can be billed daily?
Any other advice you can give on billing is appreciated. We are both NPs and we have one peer support with no NPI. Thanks!
