About H90
H90 is the ICD-10-CM diagnosis code for conductive and sensorineural hearing loss. It belongs to block H90-H94 (other disorders of ear) 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 10 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: H90.0 (bilateral), H90.1 (side), H90.2 (unspecified), H90.3 (bilateral), H90.4 (side), H90.5 (loss), H90.6 (bilateral), H90.7 (side) and 2 more.
Don't report H90 together with the conditions in its Excludes1 note: deaf nonspeaking NEC (H91.3), deafness NOS (H91.9-), hearing loss NOS (H91.9-), noise-induced hearing loss (H83.3-) and 2 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
