ICD-10 code I69.391 is a billable diagnosis code identifying dysphagia following cerebral infarction — a swallowing impairment that persists as a direct sequela of an ischemic stroke. Valid through September 30, 2026 under the FY 2026 ICD-10-CM code set, I69.391 sits within the I69.39 subcategory (“Other sequelae of cerebral infarction”) and is assigned whenever neurologically driven swallowing dysfunction is documented as a residual effect of a prior stroke rather than an acute presentation. This guide provides the practitioner-level clarity medical billers, coders, and clinical documentation specialists need to assign, sequence, and support I69.391 accurately.
What Does ICD-10 Code I69.391 Mean?
I69.391 — Dysphagia following cerebral infarction is a combination sequela code that captures both the neurological cause (cerebral infarction) and its ongoing consequence (dysphagia) in a single code. It is assigned at any point after the acute infarction encounter — there is no time-based restriction on when a sequela code may be used.
Key attributes of I69.391:
- Billable and valid for FY 2026 (October 1, 2025 – September 30, 2026) with no description change since its introduction in FY 2016
- Exempt from Present on Admission (POA) reporting for inpatient acute care admissions
- “Use additional code” instruction applies: coders should add a code from R13.11–R13.19 to specify the phase of dysphagia when that information is documented
- Grouped under MS-DRG v43.0: 056 (Degenerative nervous system disorders with MCC) and 057 (without MCC), affecting facility reimbursement
- POA exemption: Because this is a sequela of a prior event, the POA indicator is not expected
What Conditions and Diagnoses Does I69.391 Cover?
I69.391 applies when a provider explicitly links a patient’s swallowing difficulty to a previously documented cerebral infarction. The code encompasses several clinical presentations as long as the causal relationship to ischemic stroke is established:
- Oropharyngeal dysphagia resulting from cortical or brainstem infarction
- Neurogenic dysphagia documented as a sequela of ischemic CVA
- Post-stroke swallowing dysfunction confirmed by instrumental assessment (VFSS or FEES)
- Aspiration risk secondary to stroke-related dysphagia (aspiration coded separately when applicable)
- Delayed swallow initiation, reduced laryngeal elevation, or pharyngeal residue attributed to prior infarction
- Dysphagia described in documentation as a “late effect of cerebrovascular accident”
What Does I69.391 Specifically Exclude?
The following scenarios fall outside the scope of I69.391 and require different code assignments:
- Dysphagia not linked to a prior stroke — use R13.10–R13.19 as the principal or standalone diagnosis
- Sequelae of nontraumatic intracerebral hemorrhage — use I69.1xx codes instead
- Sequelae of subarachnoid hemorrhage — I69.0xx series applies
- Sequelae of other nontraumatic intracranial hemorrhage — I69.2xx series applies
- Personal history of cerebral infarction without residual deficit — use Z86.73 when there are no active sequelae
- Acute stroke encounter — use I63.xxx for the current infarction; I69.391 is not appropriate during the index stroke admission
When Is I69.391 the Right Code to Use?
Choosing I69.391 over a standalone dysphagia code requires a clear evidentiary trail in the medical record. Apply this code when all of the following criteria are met:
- A cerebral infarction (ischemic stroke) is documented in the patient’s medical history — the prior stroke does not need to be coded again, but the record must reference it.
- The current encounter involves evaluation or management of dysphagia — not the acute stroke itself.
- The provider has explicitly connected the dysphagia to the prior infarction — phrases like “secondary to stroke,” “sequela of CVA,” or “post-infarction dysphagia” satisfy this requirement; an implied relationship is insufficient for outpatient encounters.
- The swallowing impairment is not attributable to another etiology (e.g., esophageal stricture, head and neck cancer, Parkinson’s disease) — if another cause is primary, a different code hierarchy applies.
- The clinical encounter is not the initial acute stroke admission — I69.391 is appropriate from the rehabilitation phase onward, including outpatient SLP visits, SNF encounters, and long-term follow-up.
How Does I69.391 Differ From R13.10, R13.12, and I69.398?
Understanding which code leads — and which supplements — is the most common decision point for coders working post-stroke dysphagia cases.
| Code | Description | Use When | Relationship to I69.391 |
|---|---|---|---|
| I69.391 | Dysphagia following cerebral infarction | Post-stroke dysphagia is the documented diagnosis | Primary code; always sequenced first |
| R13.10 | Dysphagia, unspecified | No phase documented; no stroke linkage | Use only when I69.391 does NOT apply |
| R13.11 | Oral phase dysphagia | Phase specified as oral; stroke link confirmed | Add-on code to supplement I69.391 |
| R13.12 | Oropharyngeal dysphagia | Phase specified as oropharyngeal; stroke link confirmed | Add-on code to supplement I69.391 |
| R13.19 | Other dysphagia | Pharyngeal/esophageal phase, stroke link confirmed | Add-on code to supplement I69.391 |
| I69.398 | Other sequelae of cerebral infarction | Sequela not captured by a specific I69.39x code | Sibling code; not used together with I69.391 |
In practice, coders frequently encounter SLP notes that identify oropharyngeal dysphagia following stroke — in those cases, I69.391 is sequenced first and R13.12 is added to identify the phase. Assigning R13.12 alone without I69.391 in a confirmed post-stroke patient is a common coding error auditors flag.
What Documentation Is Required to Support I69.391?
Strong medical record documentation is the foundation of defensible I69.391 coding. Without an explicit provider-established link between the swallowing impairment and the prior infarction, the code is unsupported — and vulnerable to claim denial or audit recoupment.
What Must the Provider Document in the Clinical Notes?
The following elements must appear in the clinical record to support I69.391 assignment:
- Reference to the prior cerebral infarction — date of stroke, affected vessel or territory, or prior hospitalization reference
- Explicit causal statement linking current dysphagia to the stroke (e.g., “dysphagia secondary to ischemic CVA,” “post-stroke swallowing impairment”)
- Current functional swallowing status — FOIS (Functional Oral Intake Scale) level, diet texture, or liquid consistency modifications
- Assessment by qualified provider — physician, NP, PA, or SLP note documenting the swallowing evaluation findings
- Treatment plan or clinical decision — recommendation for modified diet, compensatory strategies, or therapeutic intervention
Which Diagnostic Tests Support This Code?
While no specific test is required to assign I69.391, the following diagnostic findings strengthen documentation and support medical necessity for related procedures:
- Videofluoroscopic Swallow Study (VFSS / Modified Barium Swallow) confirming oropharyngeal phase dysfunction
- Fiberoptic Endoscopic Evaluation of Swallowing (FEES) — particularly useful in inpatient and SNF settings
- Clinical bedside swallow evaluation with documented findings (delayed initiation, coughing, wet voice quality)
- Chest imaging if aspiration pneumonia is suspected as a complication
What Is the Documentation Standard for Inpatient vs. Outpatient Settings?
| Setting | Documentation Standard | Who Can Establish Diagnosis |
|---|---|---|
| Inpatient (acute or rehab) | Physician or qualified provider must document the causal link; SLP findings alone are insufficient to drive code selection | Attending physician, consulting physiatrist |
| Outpatient (SLP clinic, follow-up) | Provider must explicitly link dysphagia to prior stroke in the note — implied relationships do not qualify per ICD-10-CM Official Coding Guidelines for outpatient settings | Ordering/treating physician or NP/PA with prescriptive authority |
| SNF / Long-Term Care | MDS coding and physician orders should reflect the stroke-dysphagia link; SLP documentation supports but does not replace physician attestation | Attending physician or covering provider |
How Does I69.391 Affect Medical Billing and Claims?
From a revenue cycle perspective, I69.391 carries meaningful downstream implications for DRG assignment, medical necessity determinations, and therapy utilization review. Billers should note:
- MS-DRG impact: I69.391 maps to MS-DRG 056/057 (Degenerative nervous system disorders), which carries different reimbursement weights than stroke-specific DRGs — a critical distinction for case mix analysis
- Medical necessity for SLP services: I69.391 supports CPT codes for dysphagia evaluation and treatment when paired with appropriate functional documentation; payers often require evidence of skilled care necessity and measurable functional goals
- SNF Consolidated Billing: Under the SNF consolidated billing rule, most therapy services billed separately must be scrutinized when the patient is in a Part A SNF stay; I69.391 may appear as a secondary code driving therapy necessity
- Medicare Advantage plan scrutiny: MA plans often apply clinical criteria that require documented instrumental swallow study results when I69.391 drives high-cost rehabilitation claims
What CPT Codes Are Commonly Billed With I69.391?
| CPT Code | Description | Typical Pairing Context |
|---|---|---|
| 92610 | Evaluation of oral and pharyngeal swallowing function | Initial SLP evaluation post-stroke |
| 92611 | Motion fluoroscopic evaluation of swallowing function (MBSS) | VFSS ordered to confirm dysphagia phase |
| 92612 | FEES — evaluation only | Inpatient or SNF dysphagia assessment |
| 92507 | Treatment of speech, language, voice, communication, and/or auditory processing disorder | Ongoing SLP therapy sessions |
| 92526 | Treatment of swallowing dysfunction and/or oral function for feeding | Direct swallowing rehabilitation |
| 99213–99215 | Office/outpatient E/M visit | Physician follow-up managing post-stroke sequelae |
Are There Prior Authorization or Coverage Restrictions?
- Many commercial payers require prior authorization for FEES (CPT 92612) when performed in an outpatient setting; confirm payer-specific LCD requirements before scheduling
- Medicare Part B covers dysphagia treatment under SLP benefits when the service is medically necessary and the provider documents skilled care requirements — functional maintenance programs may require additional justification
- Some Medicare Advantage and Medicaid managed care plans apply visit limits or step-therapy requirements (e.g., bedside evaluation before authorizing VFSS)
- Payers may request clinical documentation linking I69.391 to a specific prior infarction with dates — coders should ensure the medical billing documentation requirements in the record are complete before submission
What Coding Errors Should You Avoid With I69.391?
Even experienced coders make predictable mistakes with post-stroke sequela coding. Auditors commonly flag these patterns during claims review for I69.391:
- Assigning R13.10 or R13.12 as the primary code when a stroke-dysphagia link is clearly documented — I69.391 must lead when the cause-and-effect relationship is established
- Using I69.391 during the acute stroke admission — sequela codes are not appropriate during the initial encounter for the infarction itself
- Failing to add the R13.1x specificity code when the SLP note or swallow study clearly identifies the dysphagia phase; leaving the code at unspecified dysphagia reduces clinical data quality and can draw payer scrutiny
- Applying I69.391 when dysphagia is attributable to a hemorrhagic stroke — hemorrhagic CVA sequelae fall under I69.1xx (intracerebral) or I69.0xx (subarachnoid), not I69.3xx
- Coding both I69.391 and a separate acute stroke code (I63.xxx) in the same encounter when only sequelae — not active stroke — are being managed
- Relying solely on SLP documentation to support I69.391 in outpatient settings — the ordering or treating physician must establish the diagnosis
What Do Auditors Look for When Reviewing Claims With I69.391?
Auditors focusing on coding audit preparation for I69.391 typically examine:
- Whether the medical record contains a physician attestation explicitly linking dysphagia to the prior infarction (not merely an SLP assessment)
- Presence of a documented prior stroke — date, type, or reference to prior hospitalization
- Correct sequencing: I69.391 before any R13.1x add-on code
- Whether therapy claims (CPT 92507, 92526) are supported by measurable functional goals and progress notes demonstrating skilled-care necessity
- Whether the POA indicator was incorrectly applied (it should be exempt)
- Inconsistencies between the ICD-10 code and the physician’s clinical narrative in office notes
How Does I69.391 Relate to Other ICD-10 Codes?
I69.391 exists within a broader family of cerebrovascular sequela codes and swallowing-disorder codes. Understanding the hierarchy prevents both under-coding and over-coding.
| Code | Description | Relationship to I69.391 | Key Distinction |
|---|---|---|---|
| I69.390 | Apraxia following cerebral infarction | Sibling code | Motor planning disorder, not swallowing |
| I69.392 | Facial weakness following cerebral infarction | Sibling code | Cranial nerve VII deficit, may coexist |
| I69.393 | Ataxia following cerebral infarction | Sibling code | Coordination deficit, not swallowing |
| I69.398 | Other sequelae of cerebral infarction | Sibling code | Catch-all; use only when no specific code applies |
| R13.10–R13.19 | Dysphagia, various phases | Supplementary codes | Added to specify phase; do NOT replace I69.391 |
| I63.5xx | Cerebral infarction due to occlusion of cerebral arteries | Prior causal code | The original infarction, not reported again at sequela visit |
| Z86.73 | Personal history of TIA and cerebral infarction without sequelae | Alternate history code | Use only when no residual deficit remains |
| J69.0 | Pneumonitis due to aspiration | Complication code | Add separately when aspiration pneumonia is documented |
What Is the Correct Code Sequencing When I69.391 Appears With Other Diagnoses?
Per the ICD-10-CM Official Coding Guidelines (Section I.C.9 and the general sequela guidance), follow this sequencing order:
- I69.391 — sequenced first as the primary sequela code driving the encounter
- R13.1x (e.g., R13.12 for oropharyngeal dysphagia) — sequenced second when phase is documented
- Additional sequelae codes (e.g., I69.392 for facial weakness, I69.351 for hemiplegia) — added in order of clinical significance
- Complication codes (e.g., J69.0 for aspiration pneumonia) — sequenced per principal diagnosis rules for the encounter type
- Comorbidity codes — hypertension (I10), diabetes, atrial fibrillation, etc., sequenced per encounter relevance
Real-World Coding Scenario — How I69.391 Is Applied in Practice
Patient encounter: A 71-year-old male presents to outpatient speech-language pathology eight months after a right middle cerebral artery (MCA) ischemic stroke. The referring physician’s note states: “Patient with known right MCA infarction (March 2024) with persistent oropharyngeal dysphagia. Referred to SLP for ongoing management.” The SLP documents oropharyngeal dysphagia with silent aspiration on thin liquids, confirmed by VFSS. The patient is on a IDDSI Level 2 (mildly thick liquid) diet.
Correct Code Application
- I69.391 — Dysphagia following cerebral infarction (primary code; physician note explicitly links dysphagia to prior stroke)
- R13.12 — Oropharyngeal dysphagia (phase confirmed by VFSS and SLP documentation)
- CPT 92507 — Treatment of speech/language/swallowing disorder (SLP therapy session)
The physician’s explicit causal language in the referral note is the anchor for I69.391 — without it, only R13.12 would be supportable in outpatient coding.
Common Mistake in This Scenario
- Incorrect approach: Coder assigns R13.12 as the standalone primary code, noting that the SLP documented oropharyngeal dysphagia clearly
- Why it fails: The physician referral and clinical record contain an established causal link to the prior infarction; omitting I69.391 misrepresents the clinical picture, reduces diagnosis code specificity, and may trigger a query from a CDI specialist or payer — because R13.12 alone suggests idiopathic swallowing dysfunction rather than neurogenic, post-stroke pathology
Frequently Asked Questions About ICD-10 Code I69.391
Is ICD-10 Code I69.391 Still Valid in FY 2026?
ICD-10 code I69.391 remains a valid, billable diagnosis code for FY 2026, effective October 1, 2025 through September 30, 2026, with no changes to its description or classification since it was introduced in FY 2016. Coders should verify annually against the CMS ICD-10-CM tabular list to confirm ongoing validity.
When Should I Use R13.12 Instead of I69.391?
R13.12 (oropharyngeal dysphagia) should be used as the primary code only when there is no documented causal link to a prior cerebral infarction. When a stroke-dysphagia relationship is established by the provider, I69.391 leads and R13.12 is added as a supplemental phase-specificity code — not the other way around.
Can I69.391 Be Assigned During the Acute Stroke Hospitalization?
No. I69.391 is a sequela code and is not appropriate during the index inpatient admission for the cerebral infarction. During the acute stroke encounter, code the infarction with I63.xxx and any associated acute presentations separately. I69.391 applies beginning at the rehabilitation phase and any subsequent encounter where residual swallowing dysfunction is managed.
Does I69.391 Require a Separate Code for the Original Stroke?
No. Unlike some sequela coding conventions, I69.391 is a combination code that implies the prior cerebral infarction without requiring the I63.xxx code to be reported again at the sequela encounter. The ICD-10-CM Official Coding Guidelines indicate that the prior causal condition does not need to be re-coded when a specific sequela code already encompasses it.
What Is the Difference Between I69.391 and I69.398?
I69.391 is assigned specifically when the documented sequela is dysphagia — a swallowing impairment. I69.398 is the catch-all code for “other sequelae of cerebral infarction” that do not have their own unique code in the I69.39x subcategory. The two codes are never assigned together; if dysphagia is present, I69.391 always takes precedence over I69.398 for that specific deficit.
What Documentation Language Triggers I69.391 Most Reliably?
Provider documentation using terms such as “post-stroke dysphagia,” “swallowing dysfunction secondary to cerebral infarction,” “neurogenic dysphagia following ischemic CVA,” or “dysphagia as a sequela of stroke” directly supports I69.391 assignment. Vague language such as “history of stroke, now with dysphagia” may be sufficient in an inpatient setting but typically requires a physician query in outpatient coding to confirm the causal relationship.
How Does I69.391 Affect DRG Assignment in the Inpatient Setting?
When I69.391 appears as a principal diagnosis in an acute inpatient setting, it maps to MS-DRG 056 (with MCC) or 057 (without MCC) under the degenerative nervous system disorders grouping. This DRG pairing carries a different relative weight than the cerebrovascular DRG family (061–069), which is an important consideration for case mix management and revenue cycle compliance reviews.
Key Takeaways
Every coder and biller working with post-stroke patients should commit these core principles to practice:
- I69.391 is the correct primary code whenever a provider explicitly documents dysphagia as a sequela of a prior cerebral infarction — not R13.10 or R13.12 alone
- Sequela codes carry no time restriction; I69.391 is appropriate months or years after the original stroke
- Always add an R13.1x specificity code when the dysphagia phase is identified in clinical or instrumental swallow assessment documentation
- Outpatient coding requires an explicit physician-documented causal link — implied relationships are insufficient under ICD-10-CM Official Coding Guidelines
- I69.391 is POA-exempt in acute inpatient settings — do not assign a POA indicator
- DRG assignment under MS-DRG 056/057 has revenue implications distinct from stroke DRGs — flag for case mix analysis
- Audit risk concentrates around missing physician attestation, incorrect primary code assignment (R13.1x without I69.391), and improper use during the acute stroke encounter
For comprehensive sequela coding guidance, refer to the CMS ICD-10-CM Official Guidelines for Coding and Reporting and the AHA Coding Clinic references specific to cerebrovascular sequelae. Additional clinical context on post-stroke swallowing dysfunction is available through CDC stroke surveillance data and the WHO ICD-10 classification reference.
