ICD-10 Code H93.212 – Auditory recruitment, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.212 – Auditory recruitment, left ear
What it is
H93.212 identifies auditory recruitment affecting the left ear. It describes an abnormal increase in loudness perception, where soft sounds may be missed but louder sounds seem unusually intense.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include reduced tolerance for louder sounds, rapid loudness growth, and difficulty judging sound intensity in the affected ear.
When to use this code
Use this code when the provider documents auditory recruitment specifically in the left ear. It is appropriate when the condition is described on audiology or ENT evaluation and laterality is clearly stated. Check documentation if the note only says hearing loss or sound sensitivity without recruitment.
Do not use for
Do not use it for general hearing loss, tinnitus, or nonspecific hyperacusis unless recruitment is documented. If the record does not identify the left ear, check documentation before assigning H93.212.
Coding tip
Verify both the finding and laterality in the source note before coding, because H93.212 is ear-specific.
