R47.9

Unspecified speech disturbances

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R47.9 is a billable code used to indicate a diagnosis of unspecified speech disturbances.

Key Diagnostic Point:

Unspecified speech disturbances encompass a range of speech-related issues that do not fit neatly into defined categories. These disturbances may manifest as difficulties in articulation, fluency, or voice quality, and can arise from various underlying conditions. Symptoms may include slurred speech, stuttering, or abnormal pitch and volume. The etiology of these disturbances can be multifactorial, including neurological disorders (e.g., stroke, traumatic brain injury), psychological factors (e.g., anxiety, stress), or developmental disorders (e.g., speech delays in children). Clinical evaluation often involves a thorough history and physical examination, alongside assessments by speech-language pathologists. Laboratory findings may be limited, but imaging studies like MRI or CT scans may be warranted to rule out structural causes. Accurate diagnosis is crucial, as treatment options vary widely based on the underlying cause.

Medium Complexity

Complexity Factors

  • Variety of potential underlying causes
  • Overlap with other speech-related codes
  • Need for comprehensive documentation
  • Potential for misdiagnosis

Audit Risk Factors

  • Insufficient documentation of symptoms
  • Failure to specify the underlying cause
  • Inconsistent coding practices
  • Use of R47.9 when a more specific code is available

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specificity in coding speech disturbances, but R47.9 remains a catch-all code that can lead to ambiguity if not properly documented.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specificity in coding speech disturbances, but R47.9 remains a catch-all code that can lead to ambiguity if not properly documented.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specificity in coding speech disturbances, but R47.9 remains a catch-all code that can lead to ambiguity if not properly documented.
