As a speech-language pathologist, you’ll be familiar with finding the right ICD-10 codes for dysarthria. 

This article provides an overview of the dysarthria ICD-10 code, including the diagnostic criteria, differential diagnoses, and other important diagnosis codes related to speech, language, and swallowing disorders. 

Using the correct ICD-10 codes for diagnosis and treatment planning can avoid unnecessary delays with insurance companies. However, it can be challenging to keep track of every single diagnosis code, especially with regular revisions of diagnostic and coding information.

What is the ICD-10?

The International Classification of Diseases, Tenth Revision (ICD-10) is a guide published by the World Health Organization (WHO) that uses standard diagnostic language. 

In the United States, clinicians use two variations of these coding guides:

  • The American Psychiatric Association’s (APA) Diagnostic and Statistical Manual of Mental Health Disorders, Fifth Edition (DSM-5), which also contains ICD-10 codes

  • The ICD-10-Clinical Modification (CM), an adapted version used to classify medical diagnoses in the U.S. 

Using the same ICD-10 code for dysarthria allows clinicians and statisticians to better measure and track health information and enables greater specificity in identifying health conditions.


What is the ICD-10 code for dysarthria?

ICD-10 codes are used to record diagnoses, accompany assessments, and bill insurance payers. 

There are several dysarthria ICD-10 codes under the section R47 “Speech disturbances, not elsewhere classified” and subheading R47.1 “Dysarthria and anarthria.” 

The specific ICD-10 code for dysarthria is R47.1. 

Synonyms for the dysarthria ICD-10 diagnosis code include:

  • Dysarthria

  • Dysarthria, flaccid

  • Dysarthria, lingual

  • Dysarthria, spastic

  • Flaccid dysarthria

  • Lingual dysarthria

  • Spastic dysarthria

There is no specific spastic dysarthria ICD-10 code, or ataxic dysarthria ICD-10 code as they both fall under the R47.1 code. 

However, the CVA with dysarthria ICD-10 code is different. In cases of dysarthria following very specific conditions, like an intracerebral hemorrhage or cerebrovascular disease, use a different set of ICD-10 codes, such as:

Dysarthria ICD-10 diagnosis criteria

The American Speech Language Hearing Association (ASHA) specifies that the ICD-10 dysarthria code is to be used for the diagnosis of a speech condition caused by muscle weakness, which may occur with other speech and language disorders. 

According to ASHA, dysarthria refers to a group of neurogenic speech disorders characterized by “abnormalities in the strength, speed, range, steadiness, tone, or accuracy of movements required for breathing, phonatory, resonatory, articulatory, or prosodic aspects of speech production.”

An assessment for dysarthria uses a perpetual method of classification. ASHA advises when diagnosing dysarthria to rely primarily on auditory perceptual attributes of speech to pinpoint the underlying pathophysiology. 

The assessment should identify and describe:

  • Impairments in body structure and function, including strengths and weaknesses in speech production and verbal/nonverbal communication.

  • Limitations in activity and participation, including functional status in communication, interpersonal interactions, self-care, and learning.

  • Contextual factors that serve as barriers or protective factors related to successful communication and life participation.

  • The impact of communication impairments on quality of life and functional limitations relative to the individual’s premorbid social roles and abilities individually and within their community.

There are specific signs and symptoms of dysarthria, which vary by dysarthria type

ASHA states that dysarthria can alter speech intelligibility and/or speech naturalness by impacting one or more of the five speech subsystems:

  1. Respiration: Short phrases, reduced loudness, excessive loudness variation, loudness decay, monoloudness, forced expiration/inspiration.

  2. Phonation: Pitch level (higher or lower than baseline), monopitch, pitch breaks, audible inhalation/inhalatory stridor, atypical voice quality (roughness, breathiness, strain, harshness, hoarseness), vocal flutter, diplophonia, voice tremor, reduced control of voice onset and offset, devoicing.

  3. Articulation: Distorted vowels, imprecise consonants, articulatory blurring, irregular articulatory breakdown.

  4. Resonance: Hypernasality, audible nasal emission/nasal snort, denasality or hyponasality.

  5. Prosody: Atypical rate, reduced stress, short rushes of speech, atypical intonation, prolonged intervals, excessive and equal stress, atypical silences.

Physical signs and symptoms may affect the articulatory structures (such as the head, jaw, lip, or tongue) and include:

  • Abnormal muscle tone at rest

  • Mucosal membrane changes

  • Muscle wasting

  • Decreased muscular range of motion

  • Fasciculations

  • Tremors

  • Weakness

  • Involuntary movements

  • Abnormal reflexes


Other diagnosis codes related to speech, language, and swallowing disorders

Even though clients may meet some criteria for using the dysarthria ICD-10 code, there may be a more appropriate diagnosis, such as:

  • Phonological disorder (F80.0)

  • Childhood onset fluency disorder (F80.81)

  • Dysphagia unspecified (R13.10)

  • Dysphagia, oral phase (R13.11)

  • Dysphagia, oropharyngeal phase (R13.12)

  • Dysphagia, pharyngeal phase (R13.13)

  • Dysphagia, pharyngoesophageal phase (R13.14)

  • Other dysphagia (R13.19)

  • Apraxia (R48.2)

  • Dysarthria related to cerebrovascular disease I69.922

  • Mixed receptive expressive language disorder (F80.2)

  • Feeding difficulties (R63.3)

  • Other symbolic dysfunctions (F48.8)

  • Expressive language delay due to hearing loss (F80.4)
