About H65.113

H65.113 is the ICD-10-CM diagnosis code for acute and subacute allergic otitis media (mucoid) (sanguinous) (serous), bilateral. It belongs to category H65 (nonsuppurative otitis media), block H65-H75 (diseases of middle ear and mastoid) 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 H65.11 (acute and subacute allergic otitis media (mucoid) (sanguinous) (serous)), H65.113 is specifically for acute and subacute allergic otitis media (mucoid) (sanguinous) (serous), bilateral. Related codes cover right ear (H65.111), left ear (H65.112), recurrent, right ear (H65.114), recurrent, left ear (H65.115), recurrent, bilateral (H65.116), recurrent, unspecified ear (H65.117) and unspecified ear (H65.119).

Use an additional code for any associated perforated tympanic membrane (H72.-). Use an additional code, if applicable, 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), infectious agent (B95-B97), occupational exposure to environmental tobacco smoke (Z57.31) and 2 more.

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 152 (Otitis Media and URI with MCC, relative weight 1.1151) and DRG 153 (Otitis Media and URI without MCC, relative weight 0.7421), in MDC 03 (Diseases and Disorders of the Ear, Nose, Mouth and Throat), 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 381.02 (acute mucoid otitis media), 381.03 (acute sanguinous otitis media), 381.04 (acute allergic serous otitis media) and 2 more.
