🧬 ICD-10 CM I69.322 — Dysarthria Following Cerebral Infarction
Billable Code Confirmed
Non-Billable Parent Codes
I69.32 “Speech and language deficits following cerebral infarction” is a non-billable subcategory that groups all speech-related sequelae together without specifying the exact deficit type^2. I69.3 “Sequelae of cerebral infarction” is a broader non-billable category covering all types of residual stroke deficits, not just speech-related ones^3. I69 “Sequelae of cerebrovascular disease” is the top-level non-billable header for all late effects of any cerebrovascular event^4.
Clinical Context
Dysarthria refers to slurred or unclear speech caused by muscle weakness controlling articulation, which must be clinically distinguished from aphasia (a language comprehension/production disorder) since both frequently coexist after stroke but require different codes^5.
Code Classification
This is a diagnosis code used to report a residual neurological deficit (sequela), not an acute condition or procedure code^1.
🔍 Code Description
ICD-10 CM I69.322 captures dysarthria, a motor speech disorder characterized by slurred, slow, or poorly articulated speech, that persists as a residual effect after a cerebral infarction has resolved into its chronic phase. Dysarthria results from weakness or incoordination of the muscles used for speech production, including the lips, tongue, and vocal cords, and is distinct from I69.320 aphasia, which reflects a higher-level language processing deficit rather than a motor speech problem. Because both conditions frequently coexist after a stroke affecting the dominant hemisphere or brainstem, coders must carefully review speech-language pathology documentation to determine whether the deficit described is motor (dysarthria) or linguistic (aphasia) in nature before assigning the correct code.
This code sits within the I69.32 “Speech and language deficits following cerebral infarction” subcategory, which also includes fluency disorders and other communication deficits distinct from dysarthria. Unlike hemiplegia sequelae codes such as I69.351, which require a fifth and sixth character to specify laterality and dominance, I69.322 does not carry a laterality component, since dysarthria is not classified by side of body affected. Documentation should clearly state the deficit occurred “following” or as a “late effect of” the cerebral infarction, distinguishing it from an acute presentation still under active stroke treatment, which would instead be coded to the acute infarction category I63.

Specificity Insight
Speech-language pathology claims are frequently denied when coded to the vague I69.32 header instead of the specific I69.322 dysarthria code, since payers require the sixth-character specificity to establish medical necessity for articulation therapy^2.
Tip
Review the SLP evaluation note carefully, since dysarthria (motor) and dysphasia/aphasia (language) are commonly conflated in casual physician documentation but require distinctly different codes.
✅ Includes
- Dysarthria (speech disorder) due to stroke — the primary clinical presentation captured by this code I69.322.
- Dysarthria as late effect of cerebrovascular accident — reflects the chronic, residual nature of the deficit I69.322.
- Dysarthria as late effect of cerebrovascular disease — broadens the causal terminology while remaining coded identically I69.322.
❌ Excludes
Excludes 1
- Z86.73 - Personal history of cerebral infarction without residual deficits — this code specifically indicates the absence of any residual deficit, which directly contradicts the presence of documented dysarthria, so the two cannot be reported together^6.
- Z86.73 - Personal history of prolonged reversible ischemic neurologic deficit (PRIND) — PRIND is defined by eventual full resolution of neurologic symptoms, making it inherently incompatible with a permanent residual deficit code^6.
Danger
The most common Excludes 1 error is defaulting to Z86.73 “history of stroke” for any post-stroke patient without checking whether an actual residual deficit like dysarthria is still present and documented.
Excludes 2
- S06.- Sequelae of traumatic intracranial injury — may be coded together with I69.322 when a patient has both a documented history of traumatic brain injury and a separate cerebral infarction independently contributing to speech deficits.
📋 Clinical Overview
Dysarthria vs Aphasia vs Dysphasia Following Stroke
Distinguishing between motor speech disorders and language-processing disorders is essential since SLP treatment plans, billing codes, and functional prognosis differ significantly between these presentations. This table compares I69.322 against the related aphasia and dysphasia sequela codes to clarify documentation cues.
| Feature | I69.322 | I69.320 | I69.321 |
|---|---|---|---|
| Deficit type | Motor speech disorder — impaired articulation due to muscle weakness/incoordination | Language disorder — impaired comprehension and/or production of language | Partial language disorder — milder form of impaired language function |
| Typical lesion location | Brainstem, cerebellum, or bilateral corticobulbar pathways | Typically dominant (usually left) hemisphere, frontal/temporal lobes | Similar to aphasia but with partial preservation of language function |
| Therapy focus | Articulation exercises, oral-motor strengthening, pacing strategies | Language comprehension and expression retraining, augmentative communication | Similar language-focused therapy, often less intensive than full aphasia |
Important
A CDI trigger should fire whenever documentation says only “speech problems” or “slurred speech” without specifying whether the deficit is motor or linguistic, since this ambiguity prevents accurate code assignment.
Manifestations & Symptom Burden
- Slurred or mumbled speech due to weakness of the articulatory muscles (lips, tongue, soft palate).
- Reduced speech volume or breathiness from impaired respiratory support for speech.
- Abnormal speech rate, either too slow or with irregular, jerky rhythm.
- Nasal-sounding speech (hypernasality) when soft palate muscles are affected.
- Difficulty being understood by listeners despite intact language comprehension and word choice.
Tip
Document severity (mild, moderate, severe) and functional impact on communication whenever possible, since this supports medical necessity documentation for ongoing SLP therapy authorization.
💰 HCC Risk Adjustment
ICD-10 CM I69.322 does not map to any payment HCC category under the current CMS-HCC V28 model, so it carries no direct RAF impact for Medicare Advantage risk scores. Despite the lack of HCC weight, the code remains valuable for establishing medical necessity for speech-language pathology services and for tracking long-term stroke rehabilitation outcomes in quality reporting programs. Coders should continue to capture this diagnosis accurately regardless of its non-HCC status, since omitting it can result in denied SLP therapy claims for lack of a qualifying diagnosis code.
🏥 MS-DRG Assignment
ICD-10 CM I69.322 is rarely, if ever, appropriate as a principal diagnosis on an acute inpatient claim, since it represents a chronic residual deficit typically identified and treated well after the acute stroke admission has concluded. When reported as a secondary diagnosis, most commonly on inpatient rehabilitation facility (IRF) stays, it does not independently drive CC or MCC status and groups broadly to MDC 01 nervous system DRGs 052-054 based on other qualifying comorbidities. A frequent inpatient coding pitfall is mistakenly applying I69.322 during the acute stroke hospitalization itself, when the acute infarction code from category I63 should be used instead, since I69 codes are reserved specifically for the post-acute, residual phase of care. Coders working in acute rehab or SLP-heavy outpatient settings should confirm the timing of the encounter relative to the acute event before assigning any I69 sequela code.

🛠️ Commonly Associated CPT Codes
92507 Treatment of speech, language, voice, communication, and/or auditory processing disorder — the primary individual therapy code used for ongoing dysarthria rehabilitation sessions. 92521 Evaluation of speech fluency — may be reported if fluency assessment is also performed concurrently with dysarthria evaluation. 92522 Evaluation of speech sound production — commonly billed for the initial diagnostic workup establishing the articulation deficit. 92523 Evaluation of speech sound production with evaluation of language comprehension and expression — used when both motor speech and language deficits are being assessed in the same visit. 96125 Standardized cognitive performance testing — occasionally billed alongside speech evaluation when cognitive-communication deficits are also suspected.
NCCI Bundling Considerations
CPT 92523 bundles the individual components of 92522 (speech sound production) when both are performed at the same encounter, so only the combined code should be reported rather than billing both separately. Individual treatment codes like 92507 are generally not billed on the same day as the initial comprehensive evaluation codes (92521-92523) unless documentation clearly supports medical necessity for both a new evaluation and a separate treatment session.
🔬 ICD-10-PCS Crosswalk
F07Z9ZZ is not standard here; instead PCS crosswalk is generally not applicable to I69.322, since this is a chronic diagnosis code without an associated inpatient procedural counterpart for the speech deficit itself. Diagnostic workup procedures such as B030ZZZ Plain radiography of brain or prior MRI brain codes may appear in the same encounter to document the causal infarction location, but do not directly crosswalk from the dysarthria code itself.
💊 Coding Scenarios and Examples
Scenario 1: A 67-year-old female presents to outpatient speech-language pathology six weeks after an acute ischemic stroke; she has persistent slurred speech confirmed on evaluation as dysarthria, with no accompanying language comprehension deficit. Correct coding: I69.322 (Dysarthria following cerebral infarction) as the primary diagnosis supporting the SLP evaluation and treatment plan. Sequencing explanation: Since the acute stroke has fully resolved into the residual phase and no acute treatment is being provided at this encounter, only the sequela code is reported. CDI note: Confirm the SLP note explicitly distinguishes dysarthria from aphasia, since both diagnoses may otherwise be miscoded interchangeably.
Scenario 2: A patient admitted for inpatient rehabilitation following a recent stroke has documented dysarthria and right-sided hemiparesis affecting the dominant side, both attributed to the same cerebral infarction. Correct coding: I69.322 (Dysarthria following cerebral infarction), I69.351 (Hemiplegia and hemiparesis following cerebral infarction affecting right dominant side). Sequencing explanation: Both residual deficits are coded together as secondary diagnoses to support the intensity and multidisciplinary nature of the rehab stay, with the admitting rehab diagnosis typically sequenced first. CDI note: Ensure each distinct residual deficit (speech, motor, cognitive) is separately documented and coded to fully capture the patient’s rehabilitation needs and support IRF-PAI reporting.
Scenario 3: A patient is seen in the emergency department for acute onset slurred speech and is subsequently diagnosed with a new acute cerebral infarction; dysarthria is documented as a presenting symptom of the acute event, not a chronic sequela. Correct coding: I63.9 (Cerebral infarction, unspecified) as the principal diagnosis; I69.322 would NOT be used in this scenario. Sequencing explanation: Since the dysarthria is a symptom of the current acute stroke rather than a residual deficit from a prior, resolved event, the acute infarction code is used instead of the sequela code. CDI note: This scenario highlights the critical timing distinction; query the physician if it is unclear whether the stroke is a new acute event or a previously known chronic condition presenting with a new symptom.
⚠️ Coding Pitfalls and Tips
- Never assign I69.322 during the acute phase of a stroke; use the appropriate acute infarction code from category I63 instead, since I69 codes are reserved for the post-acute residual period only.
- Always confirm whether documented “speech problems” are motor (dysarthria, I69.322) or linguistic (aphasia, I69.320) in nature before code assignment, since SLP documentation often uses these terms loosely.
- Do not report I69.322 alongside Z86.73, since Z86.73 specifically indicates the absence of residual deficits, which contradicts an active dysarthria diagnosis.
- Remember that I69.322 carries no HCC weight, but it remains essential for supporting medical necessity of speech therapy claims, so it should never be omitted for lack of RAF impact.
- When multiple residual deficits coexist (dysarthria, hemiparesis, cognitive deficits) after the same stroke, code each individually using the appropriate I69 subcategory rather than relying on a single combined code.
