Code Description

ICD-10 H91.23 is a billable code used to indicate a diagnosis of sudden idiopathic hearing loss, bilateral.

Key Diagnostic Point:

Sudden idiopathic hearing loss (SIHL) is characterized by a rapid onset of hearing loss, typically occurring over a period of 72 hours or less, without an identifiable cause. When this condition affects both ears, it is classified as bilateral SIHL. Patients may present with a range of symptoms, including a feeling of fullness in the ears, tinnitus (ringing in the ears), and a noticeable decrease in hearing ability. The etiology of SIHL remains largely unknown, although it may be associated with viral infections, vascular events, or autoimmune disorders. Diagnosis is primarily clinical, supported by audiometric testing to confirm the degree and type of hearing loss. Management often involves corticosteroids to reduce inflammation and promote recovery, although the effectiveness of treatment can vary. Early intervention is crucial, as prompt treatment may improve outcomes. Patients may also benefit from audiological rehabilitation, including hearing aids or assistive listening devices, depending on the severity of the hearing loss.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Lack of identifiable cause complicates diagnosis.
  • Requires differentiation from other types of hearing loss.
  • Potential overlap with other ear disorders.
  • Need for comprehensive documentation of clinical findings.

Audit Risk Factors

  • Insufficient documentation of clinical findings.
  • Failure to document the onset and progression of symptoms.
  • Inadequate justification for the use of corticosteroids.
  • Lack of follow-up documentation.

Coding Guidelines

Inclusion Criteria

Use H91.23 When
  • According to ICD
  • 10 coding guidelines, H91
  • 23 should be used when the hearing loss is sudden and idiopathic, affecting both ears
  • It is important to document the absence of known causes and to differentiate from other hearing loss codes

Exclusion Criteria

Do NOT use H91.23 When
  • Exclusion criteria include hearing loss due to trauma, infection, or other identifiable conditions

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of hearing loss conditions, including idiopathic cases. H91.23 provides a distinct code for bilateral sudden hearing loss, improving data accuracy and facilitating better patient management.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of hearing loss conditions, including idiopathic cases. H91.23 provides a distinct code for bilateral sudden hearing loss, improving data accuracy and facilitating better patient management.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of hearing loss conditions, including idiopathic cases. H91.23 provides a distinct code for bilateral sudden hearing loss, improving data accuracy and facilitating better patient management.
