HN Modifier: Bachelors Degree Billing Guide

The HN modifier, like the HO modifier, is a HCPCS modifier used in coding some claims.

These modifiers are different from CPT or procedure codes and are used to describe something else about the claim.

One commonly used example is the HJ modifier which is usually used to code Employee Assistance Program (EAP) visits. Modifiers are normally used in addition to the CPT codes to fully describe the service.
