Code Description

ICD-10 R47.01 is a billable code used to indicate a diagnosis of aphasia.

Key Diagnostic Point:

Aphasia is a communication disorder that affects a person's ability to process and use language. It can manifest as difficulty in speaking, understanding speech, reading, or writing. Aphasia is often caused by damage to the areas of the brain responsible for language, typically due to stroke, traumatic brain injury, or neurological diseases such as Alzheimer's disease or brain tumors. Symptoms can vary widely, from mild word-finding difficulties to complete inability to communicate. Patients may exhibit signs such as speaking in incomplete sentences, using nonsensical words, or struggling to comprehend spoken or written language. Clinical assessment often includes a detailed history, neurological examination, and language assessments conducted by speech-language pathologists. Laboratory findings may not be directly associated with aphasia but can help identify underlying causes, such as imaging studies revealing brain lesions. Accurate diagnosis and coding are crucial for effective treatment planning and resource allocation.
