HCPCS H0015 reports an intensive outpatient program (IOP) for alcohol and/or drug services. It is typically billed per diem and is common in Medicaid substance use treatment.
When to use H0015
Use H0015 for a structured intensive outpatient substance use or co-occurring disorders program. It is distinct from individual counseling H-codes and from CPT psychotherapy.
How to bill it
Report per day (per diem), following the relevant state Medicaid program’s definitions and authorization requirements.
Common pitfalls
- Billing individual service codes separately when they are included in the IOP per diem.
- Assuming a national per-unit standard for a state-defined code.
Frequently asked questions
How is H0015 billed?
H0015 is typically billed per diem (per day) for an intensive outpatient program; confirm the daily definition in your state Medicaid manual.
Can I bill individual counseling on the same day as H0015?
Usually no—individual services included in the IOP are bundled into the per diem. Verify your payer’s bundling rules.
