Slurred speech

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 R47.81 is a billable code used to indicate a diagnosis of slurred speech.

Key Diagnostic Point:

Slurred speech, or dysarthria, is characterized by unclear or poorly articulated speech that can result from various neurological conditions affecting the muscles involved in speech production. This symptom may present as a result of conditions such as stroke, multiple sclerosis, amyotrophic lateral sclerosis (ALS), or intoxication from substances like alcohol or drugs. Patients may exhibit difficulty in pronouncing words, a slow or irregular speech rate, and changes in voice quality. The clinical context of slurred speech is critical, as it can indicate acute neurological events requiring immediate medical attention or chronic conditions that may need long-term management. Accurate identification of slurred speech is essential for appropriate diagnosis and treatment, as it can significantly impact a patient's communication abilities and quality of life.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying causes (neurological, metabolic, toxic)
  • Potential overlap with other speech disorders
  • Need for comprehensive patient history and examination
  • Variability in presentation based on etiology

Audit Risk Factors

  • Inadequate documentation of the underlying cause of slurred speech
  • Failure to specify acute vs. chronic presentation
  • Misclassification of slurred speech as a symptom of a different condition
  • Lack of supporting clinical findings in the medical record

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Detailed patient history, including onset, duration, and associated symptoms; neurological examination findings.

Common Clinical Scenarios

Patients presenting with slurred speech due to transient ischemic attacks (TIAs) or chronic conditions like multiple sclerosis.

Billing Considerations

Consideration of comorbidities that may contribute to slurred speech, such as diabetes or hypertension.

Emergency Medicine

Documentation Requirements

Immediate assessment of neurological status, including the use of stroke scales (e.g., FAST), and documentation of vital signs.

Common Clinical Scenarios

Acute presentations of slurred speech in patients with suspected stroke or intoxication.

Billing Considerations

Rapid identification of life-threatening conditions and appropriate coding for acute care interventions.
