HN Modifier Description: Bachelor's Degree Level in Behavioral Health
HN shows up on the services bachelor's-level staff deliver: case management, rehabilitative skills work, ABA support, and team-based care. Where a state pays those services by credential, HN is what sets the rate.
Short answer
HN is the HCPCS Level II modifier "Bachelors degree level." Medicaid behavioral health programs use it when a bachelor's-level provider renders the service. Michigan maps bachelor's social workers, BCaBAs, and bachelor's-level case managers and supports coordinators to HN; Ohio uses it for bachelor's-level QMHS, care management specialists, and peer supporters, and for unlicensed ACT team members.
| Modifier | HCPCS descriptor | Type |
|---|---|---|
| HN | Bachelors degree level | Provider education level |
How Michigan uses HN
Michigan treats HN as a provider credential modifier that affects the rate. Its job title crosswalk includes:
| Role (Michigan crosswalk) | Modifier |
|---|---|
| Licensed or limited licensed social worker, bachelor's | HN |

How Ohio uses HN
In Ohio's practitioner table HN marks a bachelor's degree for Qualified Mental Health Specialists, care management specialists, and certified peer supporters; Ohio added HN and HO to peer recovery specifically to reflect education level. As a procedure modifier, HN identifies an ACT team member who is a trainee, assistant, or unlicensed paraprofessional.
Why HN claims deny
- Level mismatch. HN on a service the state limits to master's-level or licensed staff.
- Missing education modifier. Ohio requires HM, HN, HO, or UK on the paraprofessional roles in its table.
- Wrong credential on file. The staff member's degree in the plan's records does not match the modifier.
