ICD-10-CM Code R47.02


Version 2020 Billable Code No Valid Principal Dx

Valid for Submission

R47.02 is a billable code used to specify a medical diagnosis of dysphasia. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code R47.02 might also be used to specify conditions or terms like acquired dysphasia, anterior dysphasia, central paraphasia, dysphasia, frontal dynamic dysphasia, literal paraphasia, etc

According to ICD-10-CM guidelines this code should not to be used as a principal diagnosis code when a related definitive diagnosis has been established.

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code R47.02:

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • dysphasia following cerebrovascular disease (I69. with final characters -21)

Clinical Information

  • ANOMIA-. a language dysfunction characterized by the inability to name people and objects that are correctly perceived. the individual is able to describe the object in question but cannot provide the name. this condition is associated with lesions of the dominant hemisphere involving the language areas in particular the temporal lobe. from adams et al. principles of neurology 6th ed p484
  • APHASIA-. a cognitive disorder marked by an impaired ability to comprehend or express language in its written or spoken form. this condition is caused by diseases which affect the language areas of the dominant hemisphere. clinical features are used to classify the various subtypes of this condition. general categories include receptive expressive and mixed forms of aphasia.
  • APHASIA BROCA-. an aphasia characterized by impairment of expressive language speech writing signs and relative preservation of receptive language abilities i.e. comprehension. this condition is caused by lesions of the motor association cortex in the frontal lobe broca area and adjacent cortical and white matter regions.
  • APHASIA WERNICKE-. impairment in the comprehension of speech and meaning of words both spoken and written and of the meanings conveyed by their grammatical relationships in sentences. it is caused by lesions that primarily affect wernicke's area which lies in the posterior perisylvian region of the temporal lobe of the dominant hemisphere. from brain & bannister clinical neurology 7th ed p141; kandel et al. principles of neural science 3d ed p846
  • APHASIA CONDUCTION-. a type of fluent aphasia characterized by an impaired ability to repeat one and two word phrases despite retained comprehension. this condition is associated with dominant hemisphere lesions involving the arcuate fasciculus a white matter projection between broca's and wernicke's areas and adjacent structures. like patients with wernicke aphasia aphasia wernicke patients with conduction aphasia are fluent but commit paraphasic errors during attempts at written and oral forms of communication. from adams et al. principles of neurology 6th ed p482; brain & bannister clinical neurology 7th ed p142; kandel et al. principles of neural science 3d ed p848

Information for Patients


Aphasia is a disorder caused by damage to the parts of the brain that control language. It can make it hard for you to read, write, and say what you mean to say. It is most common in adults who have had a stroke. Brain tumors, infections, injuries, and dementia can also cause it. The type of problem you have and how bad it is depends on which part of your brain is damaged and how much damage there is.

There are four main types:

  • Expressive aphasia - you know what you want to say, but you have trouble saying or writing what you mean
  • Receptive aphasia - you hear the voice or see the print, but you can't make sense of the words
  • Anomic aphasia - you have trouble using the correct word for objects, places, or events
  • Global aphasia - you can't speak, understand speech, read, or write

Some people recover from aphasia without treatment. Most, however, need language therapy as soon as possible.
