About the R47–R49 Code Range

ICD-10 codes R47-R49 cover various symptoms and signs related to speech and voice, including difficulties with speaking, understanding language, and voice quality. These codes are used to classify speech disturbances, symbolic dysfunctions like dyslexia or agnosia, and disorders affecting voice and resonance.

This range includes R47 for speech disturbances such as aphasia and dysarthria, often linked to nervous system causes, with detailed codes like R47.01 for aphasia and R47.1 for dysarthria and anarthria. R48 covers symbolic dysfunctions including dyslexia, agnosia, and apraxia, which affect comprehension and motor planning for communication. For voice and resonance disorders, R49 includes conditions like dysphonia (hoarseness) and aphonia (loss of voice), as well as hypernasality and hyponasality affecting voice resonance. Specific subcodes, such as R49.0 for dysphonia and R49.1 for aphonia, help pinpoint the exact nature of voice impairment. These codes assist medical coders and healthcare providers in documenting complex speech and voice issues accurately for patients experiencing communication deficits due to neurological, structural, or functional causes.
