What M96 means

Diagnostic services such as imaging and some tests split into a professional component (interpretation) and a technical component (equipment, staff, supplies). When the patient is a hospital inpatient, the hospital’s inpatient payment is expected to cover technical services, so only the hospital can bill them. M96 tells you that your claim for the technical part, or for the global service, cannot be paid to you.

The remark gives two instructions: contact the inpatient facility about the technical component, and, if you have not already, bill the payer for the professional component only.

Common causes

A mobile or independent diagnostic provider billing globally for a hospital inpatient.
A patient admitted during or shortly after the service, which the provider was not told about.
Date mismatches that place an outpatient service within an inpatient stay.
A default global billing setup that does not check patient status.

How to fix it

Confirm the patient was an inpatient on the date of service with the hospital.
Rebill the professional component with modifier 26 if you provided the interpretation, as a corrected claim with frequency code 7 if the original was adjudicated.
Invoice the facility for the technical component according to your arrangement.
If the patient was not an inpatient, gather registration records and ask the payer to reprocess.

How to prevent it

Check inpatient status with the hospital before billing technical services.
Keep written arrangements with facilities that cover technical component payment.
See provider enrollment and billing setup for facility-related billing structure.

M96 FAQ

Why can't I bill the technical component?

For a hospital inpatient, the facility's inpatient payment is designed to cover technical services. Payers such as Medicare require those services to be billed by the hospital, which may then pay outside suppliers under arrangement.

What should I bill instead?

The professional component, using modifier 26, if you performed the interpretation or professional work.

How do I get paid for the technical work?

Contact the inpatient facility. Payment for the technical component comes from the facility under your agreement with it.
