Questions About H75Overview

Is H75 a billable code?

No. This is a category header that groups the codes for other disorders of middle ear and mastoid in diseases classified elsewhere, and headers cannot be submitted on claims. Claims for other disorders of middle ear and mastoid in diseases classified elsewhere need a more specific code from this category, such as H75.00, H75.01, and H75.02.

What is coded first with H75?

The Code First note reads: underlying disease. When one of these applies, it is sequenced before H75.
