Anesthesia Procedure Code Modifiers with the Minute Qualifier
Professional anesthesia capitated encounters billed with specific modifiers must use the minute qualifier, MJ. If you use the unit qualifier, UN, an edit will reject the encounter. The edit applies regardless of the date of service.
This change follows the Health Insurance Portability and Accountability Act (HIPAA) 5010 HIPAA 837 Companion Guide.
Use the MJ qualifier with these modifiers:
- AA
- AD
- QK
- QS
- QX
- QY
- QZ
Modifiers, other than the ones listed above, can process with the UN qualifier and not cause an edit.
If a professional encounter claim is sent with the above listed modifiers and the UN qualifier, the edit display will read: ANESTHESIA QUALIFIER IS INCORRECT. Resend a corrected capitated encounter with the MJ qualifier.
