Dysphasia and aphasia

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 R47.0 is a billable code used to indicate a diagnosis of dysphasia and aphasia.

Key Diagnostic Point:

Dysphasia and aphasia refer to language disorders that affect a person's ability to communicate effectively. Dysphasia is a partial loss of language ability, while aphasia is a more severe form that can result in a complete inability to communicate verbally or in writing. These conditions can manifest as difficulty in speaking, understanding speech, reading, or writing. Common symptoms include word-finding difficulties, problems with sentence structure, and challenges in comprehending spoken or written language. The underlying causes can vary widely, including stroke, traumatic brain injury, brain tumors, infections, or neurodegenerative diseases such as Alzheimer's. Diagnosis typically involves a thorough clinical evaluation, including neurological assessments and language testing, often conducted by speech-language pathologists. Imaging studies like CT or MRI may be utilized to identify structural brain abnormalities. Accurate coding requires careful documentation of the patient's symptoms, the context of their presentation, and any underlying conditions contributing to the dysphasia or aphasia.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of underlying causes requiring differential diagnosis
  • Overlap with other neurological conditions
  • Need for precise documentation of symptoms
  • Potential for misclassification with other speech disorders

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings
  • Failure to specify the type of aphasia or dysphasia
  • Misuse of related codes leading to upcoding or downcoding
  • Lack of clarity on the underlying cause of the condition
