About H66.01

H66.01 is the ICD-10-CM diagnosis code for acute suppurative otitis media with spontaneous rupture of ear drum. It belongs to category H66 (suppurative and unspecified otitis media), block H65-H75 (diseases of middle ear and mastoid) and chapter 8 (diseases of the ear and mastoid process). It is a header code, so it can't be reported by itself; one of its 8 subcodes must be used instead.

Within H66.0 (acute suppurative otitis media), H66.01 is specifically for acute suppurative otitis media with spontaneous rupture of ear drum. Related codes cover without spontaneous rupture of ear drum (H66.00).

To report this condition, pick the subcode that matches the documentation: H66.011 (right ear), H66.012 (left ear), H66.013 (bilateral), H66.014 (recurrent, right ear), H66.015 (recurrent, left ear), H66.016 (recurrent, bilateral), H66.017 (recurrent, unspecified ear) and H66.019 (unspecified ear).

Use an additional code to identify: exposure to environmental tobacco smoke (Z77.22), exposure to tobacco smoke in the perinatal period (P96.81), history of tobacco dependence (Z87.891), occupational exposure to environmental tobacco smoke (Z57.31), tobacco dependence (F17.-) and 1 more.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
