Range Overview

high priority

The ICD-10 code range H90-H94 represents 'Other disorders of ear'. These codes are used to document various non-inflammatory conditions of the ear, including conductive and sensorineural hearing loss, tinnitus, and disorders of the auditory nerve. The codes are designed to specify the type, cause, and location of the disorder, providing a comprehensive picture of the patient's ear health.

Key Usage Points:

  • •Always specify the type of hearing loss: conductive, sensorineural, or mixed.
  • •Use additional codes to identify the exposure to environmental tobacco smoke, history of tobacco use, or occupational exposure to noise.
  • •For bilateral conditions, use the bilateral code. If no bilateral code exists, use separate codes for both ears.
  • •For tinnitus, specify whether it's subjective (H93.13) or objective (H93.12).
  • •For vertigo, use additional code to identify the type (H81.-).

Coding Guidelines

When to Use:

  • ✓When a patient presents with hearing loss without inflammation.
  • ✓When a patient complains of tinnitus.
  • ✓When a patient is diagnosed with an auditory nerve disorder.
  • ✓When a patient has a non-inflammatory disorder of the ear.
  • ✓When a patient has vertigo.

When NOT to Use:

  • ✗When the condition is inflammatory in nature.
  • ✗When the condition is related to the external ear.
  • ✗When the condition is due to an injury or trauma.
  • ✗When the condition is a congenital anomaly.
  • ✗When the condition is due to a neoplasm.

Code Exclusions

Always verify exclusions with the latest ICD-10-CM official guidelines.

Documentation Requirements

Documentation for codes H90-H94 should include the type, cause, and location of the ear disorder. The patient's symptoms, the results of audiological tests, and the impact on the patient's daily life should also be documented.

Clinical Information:

  • •Type of hearing loss or ear disorder
  • •Cause of the disorder
  • •Location (left, right, or bilateral)
  • •Severity of symptoms
  • •Impact on patient's daily life

Supporting Evidence:

  • •Audiological test results
  • •Clinical examination findings
  • •Patient's medical history
  • •Patient's symptom description
Good Documentation Example:

Patient presents with bilateral sensorineural hearing loss. Audiological tests confirm moderate loss in both ears. Patient reports difficulty hearing conversations in noisy environments.

Poor Documentation Example:

Patient has hearing loss.

Common Documentation Errors:

  • âš Not specifying the type of hearing loss
  • âš Not documenting the cause of the disorder
  • âš Not indicating the location of the disorder
  • âš Not providing supporting evidence

Coding Complexity

Medium
Complexity Rating

The complexity of coding for other disorders of the ear lies in the need to accurately identify the type, cause, and location of the disorder. Coders must also understand the difference between subjective and objective tinnitus, and how to code for vertigo.

Key Factors:
  • â–¸Determining the type of hearing loss
  • â–¸Identifying the cause of the disorder
  • â–¸Coding for bilateral conditions
  • â–¸Understanding the difference between subjective and objective tinnitus
  • â–¸Coding for vertigo

Specialty Focus

These codes are primarily used by otolaryngologists and audiologists. They are also used by primary care physicians and geriatricians when dealing with age-related hearing loss.

Primary Specialties:
Otolaryngology
60%
Audiology
30%
Clinical Scenarios:
  • • A patient with sudden sensorineural hearing loss in the right ear.
  • • A patient with chronic tinnitus.
  • • A patient with bilateral conductive hearing loss due to otosclerosis.
  • • A patient with vertigo due to Meniere's disease.
  • • A patient with age-related hearing loss.

Resources & References

Resources for these codes include the ICD-10-CM official guidelines, clinical textbooks on otolaryngology and audiology, and professional coding guides.

Frequently Asked Questions

How do I code for bilateral conditions?

If a bilateral code exists, use it. If not, use separate codes for the left and right ear.
