About H93.25

H93.25 is the ICD-10-CM diagnosis code for central auditory processing disorder. It belongs to category H93 (other disorders of ear, not elsewhere classified), block H90-H94 (other disorders of ear) and chapter 8 (diseases of the ear and mastoid process). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within H93.2 (other abnormal auditory perceptions), H93.25 is specifically for central auditory processing disorder. Related codes cover auditory recruitment (H93.21), Diplacusis (H93.22), Hyperacusis (H93.23), temporary auditory threshold shift (H93.24) and other abnormal auditory perceptions (H93.29).

Don't report H93.25 together with the conditions in its Excludes1 note: mixed receptive-expressive language disorder (F80.2).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 886 (Behavioral and Developmental Disorders, relative weight 1.8678), in MDC 19 (Mental Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

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

Before ICD-10, this condition was coded in ICD-9-CM as 315.32 (mixed receptive-expressive language disorder).
