How coders use this code

ICD-10-CM H90.A21 is a billable, fully specified code, so it can be reported directly on a claim to document a diagnosis of sensorineural hearing loss, unilateral, right ear, with restricted hearing on the contralateral side. Coders assign it when the chart documentation supports this level of detail, always matching to the most specific code available and verifying against the chapter-specific guidelines published annually by NCHS/CMS.
