H93.3Disorders of acoustic nerve

Non-billable headerICD-10-CM

H93.3 is a non-billable header ICD-10-CM code for disorders of acoustic nerve. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • acoustic neuroma (D33.3)
  • syphilitic acoustic neuritis (A52.15)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Disorder of 8th cranial nerve

Risk adjustment

H93.3 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

How H93.3 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to H93.3.

  • Neuritisacoustic(nerve)

Code to one of these instead H93.3

1 child code. Green means billable.
