🧬 ICD-10 CM I69.314 — Frontal Lobe and Executive Function Deficit Following Cerebral Infarction
Billable Code Confirmed
ICD-10 CM I69.314 is a fully specified 6-character ICD-10-CM code that is valid and billable for FY2026. The 6th character “4” within the I69.31x subcategory designates the specific cognitive domain of frontal lobe and executive function deficit, distinguishing it from other cognitive sequelae such as memory deficit (I69.311), attention deficit (I69.310), or psychomotor deficit (I69.313). No additional characters are required; this code is complete as written.
Non-Billable Parent Codes
I69 (Sequelae of cerebrovascular disease) is a non-billable category header and cannot be submitted on a claim. I69.3 (Sequelae of cerebral infarction) is a non-billable subcategory lacking specificity for the type of residual deficit. I69.31 (Cognitive deficits following cerebral infarction) is also non-billable because it does not identify the specific cognitive domain affected. All three parent codes must be extended to the highest level of specificity — I69.314 — before a claim will process correctly.
Clinical Context
ICD-10 CM I69.314 is used exclusively in the post-acute period — it is a sequela code that documents a persistent neurological deficit remaining after the resolution of the acute cerebral infarction event. It is never appropriate to code I69.314 simultaneously with an acute cerebral infarction code (I63.xx) for the same event; the acute code is used during the active infarction encounter, and I69.314 is used at subsequent encounters when only the residual deficit remains. The frontal lobe and executive function domain captured by this code encompasses deficits in planning, working memory, cognitive flexibility, response inhibition, and goal-directed behavior — distinct cognitive functions from the memory, attention, or language deficits captured by sibling codes.
Code Classification
ICD-10 CM I69.314 is a diagnosis code classifying a specific cognitive sequela of a prior cerebral infarction — it is not a procedure code and does not capture the acute stroke event. Per ICD-10-CM guideline I.C.9, the sequela “S” 7th character convention used in injury coding does NOT apply to cerebrovascular sequelae codes in the I69.x category; the I69.x codes themselves carry the sequela concept built into their structure. When cognitive testing (e.g., neuropsychology evaluation) yields the specific executive dysfunction diagnosis, that formal evaluation note is the preferred documentation source for supporting I69.314.
🔍 Code Description
ICD-10 CM I69.314 classifies the residual frontal lobe and executive function deficit that persists as a direct consequence of a prior cerebral infarction (ischemic stroke). Executive function is an umbrella term for a set of high-order cognitive processes controlled predominantly by the prefrontal cortex and its subcortical connections — these include the ability to plan and sequence complex tasks, maintain working memory, shift cognitive sets (cognitive flexibility), inhibit inappropriate responses, and monitor and self-correct behavior. Following a cerebral infarction affecting frontal or prefrontal cortical regions, or the white matter tracts connecting these regions to subcortical structures, patients may present with what is clinically termed “dysexecutive syndrome” — impaired daily functioning out of proportion to basic memory or language testing results.
Frontal lobe and executive function deficits post-stroke are among the most functionally disabling yet underdiagnosed cognitive sequelae, as standardized bedside screening tools (MMSE, MoCA) have limited sensitivity for executive dysfunction without targeted frontal assessment. The deficit captured by I69.314 should be distinguished from general cognitive impairment — it specifically reflects impaired executive processing, which manifests clinically as difficulty with activities requiring planning (e.g., managing medications independently, preparing meals, managing finances), perseveration, disinhibition, and impaired judgment. CDI queries should target neuropsychology, PM&R, and neurology consult notes where formal executive function testing — Trail Making Test Part B, Frontal Assessment Battery, CLOX, or COWAT — has been administered and documented, as these provide the strongest code-level documentation support for I69.314 over the nonspecific I69.30 (unspecified sequelae).

Why I69.314 Over I69.30 (Unspecified) Matters Clinically and Operationally
Using I69.30 (unspecified sequelae) when the provider has documented specific executive dysfunction or frontal lobe cognitive deficits is a coding error that misrepresents the patient’s actual clinical status. While neither I69.314 nor I69.30 carries a V28 HCC RAF, the specificity of I69.314 directly supports quality measure reporting (e.g., post-stroke cognitive screening metrics), rehabilitation goal-setting documentation, payer authorization for neuropsychological evaluation, and defensibility under documentation integrity audits. Specific coding also reflects stronger CDI program performance.
Tip
Multiple cognitive sequela codes from the I69.31x family may be coded simultaneously when the provider documents more than one distinct cognitive domain deficit — for example, a patient with post-stroke memory deficit (I69.311) AND executive dysfunction (I69.314) AND visuospatial neglect (I69.312) can legitimately carry all three codes if each is documented as active and managed. This is not duplicate coding; these represent separately identified, clinically distinct cognitive impairments.
✅ Includes
- Dysexecutive syndrome following cerebral infarction — Clinically established loss of executive processing capacity (planning, inhibition, cognitive flexibility, working memory) as a direct result of prior ischemic stroke; supported by formal neuropsychological testing or documented behavioral observation by a qualified clinician.
- Frontal lobe behavioral syndrome post-stroke — Includes impaired judgment, disinhibition, perseveration, apathy, and loss of goal-directed behavior attributable to frontal lobe involvement in a prior cerebral infarction.
- Executive function deficit following stroke NOS — When a provider documents “executive dysfunction following stroke” or “frontal cognitive deficit post-infarct” without using the precise code terminology, I69.314 is the appropriate code per Alphabetic Index routing.
❌ Excludes
Excludes 1
- ICD-10 CM Z86.73 — Personal history of cerebral infarction without residual deficit: This is a hard Excludes 1 — if the provider has documented that the patient had a prior stroke with no remaining deficits, Z86.73 is correct and I69.314 must not be used. The distinction hinges entirely on whether a residual deficit is currently present and documented; the moment a provider documents persistent executive dysfunction attributable to a prior infarction, Z86.73 is no longer appropriate and I69.314 is indicated.
- S06.- — Sequelae of traumatic intracranial injury: Executive function deficits resulting from traumatic brain injury (TBI) are coded using the S06.x category with the appropriate 7th character “S” for sequelae — they are never coded with I69.314. This distinction is critical in patients with both a TBI history and a stroke history; the etiology of the executive deficit must be established by the treating provider before assigning either code.
Danger
The most common Excludes 1 error with I69.314 is applying it to a patient whose post-stroke workup has confirmed full neurological recovery — in that case Z86.73 is the correct code and I69.314 must not appear. The reverse error also occurs: coding Z86.73 when the patient clearly has documented persistent cognitive deficits, which constitutes undercoding. Query the attending to explicitly state whether residual cognitive deficits are present and attributable to the prior infarction whenever the record is ambiguous.
Excludes 2
There are no Excludes 2 notations specific to I69.314 in the ICD-10-CM Tabular List. However, per ICD-10-CM guideline I.C.9, when I69.314 represents a sequela of a prior infarction and the patient subsequently suffers a new acute cerebral infarction (I63.xx) during the same encounter, the acute infarction code sequences as principal and I69.314 may be reported as an additional code representing the pre-existing deficit — these are not the same condition and may coexist in the record.
📋 Clinical Overview
Post-Stroke Cognitive Sequelae: Selecting the Right I69.31x Code
Accurate selection within the I69.31x family requires that the treating provider or neuropsychologist explicitly document the affected cognitive domain — frontal/executive function, memory, attention, visuospatial, psychomotor, or social/emotional. When the physician documents only “cognitive deficit” or “cognitive impairment” without specifying the domain, the coder should query for specificity rather than defaulting to I69.30 (unspecified) or I69.318 (other). Neuropsychological testing reports are the richest documentation source for domain-specific cognitive coding and should be reviewed routinely in post-stroke inpatient rehabilitation admissions.
| Feature | I69.314 | I69.311 | I69.310 |
|---|---|---|---|
| Cognitive Domain | Frontal lobe / executive function | Memory (encoding, retrieval) | Attention and concentration |
| Clinical Presentation | Impaired planning, disinhibition, perseveration, poor judgment, working memory deficits | Difficulty forming new memories or retrieving past information; anterograde or retrograde | Poor sustained attention, distractibility, difficulty with divided attention tasks |
| Typical Stroke Location | Frontal or prefrontal cortex, anterior cingulate, dorsolateral prefrontal circuit, white matter tracts | Hippocampus, thalamus, parahippocampal gyrus, posterior cerebral artery territory | Parietal cortex, anterior attention network, thalamic nuclei |
| Formal Test Examples | Trail Making Test Part B, FAB, CLOX, COWAT, Stroop | CVLT, Wechsler Memory Scale, RBMT | Digit Span, PASAT, Conners CPT |
| HCC V28 Mapping | None — RAF 0 | None — RAF 0 | None — RAF 0 |
| DRG Principal Driver | DRG 056/057 | DRG 056/057 | DRG 056/057 |
| Codes Simultaneously? | Yes — may code with I69.311, I69.310, I69.315 when each domain is documented | Yes — may code with I69.314when both domains are separately documented | Yes — may code with I69.314when both domains are documented |
Important
Multiple I69.31x codes may be reported together when distinct cognitive domain deficits are each independently documented — this is explicitly supported by ICD-10-CM coding guidelines and is not duplicate coding. The CDI trigger is ensuring the provider’s note names each specific deficit domain rather than using umbrella language like “cognitive impairment.” Query the neuropsychologist or attending for domain-specific language when the discharge summary is nonspecific.
Manifestations & Symptom Burden
- Dysphagia (I69.391) — A separately codeable sequela of cerebral infarction that frequently co-occurs with cognitive deficits; when documented, use I69.391 and optionally an additional R13.10 code to specify dysphagia type per the Tabular instruction, and note it is a common CC trigger.
- Aphasia (I69.320) — Post-stroke language deficit may co-occur with executive dysfunction when infarction affects the dominant frontal language regions; code separately when documented alongside I69.314.
- Depression (F32.xx) — Post-stroke depression is the most common neuropsychiatric sequela and frequently complicates the clinical picture of executive dysfunction; code separately per ICD-10-CM convention and note it can serve as a CC depending on specificity.
- Hemiplegia/hemiparesis (I69.351) — Motor and cognitive deficits frequently co-occur after hemispheric cerebral infarction; both the cognitive sequela (I69.314) and the motor sequela (I69.351 or I69.35x) should be coded when each is documented.
- Facial weakness (I69.392) — Facial droop following cerebral infarction is a separately codeable sequela and is commonly present alongside cognitive deficits in middle cerebral artery territory infarctions.
Tip
Manifestation and sequela coding for I69.314 does not follow the typical “underlying condition / manifestation” sequencing rule — the I69.31x codes are themselves the sequela codes and do not require a separate “cause” code to be listed first in the post-acute encounter. In the acute setting, the I63.xx (cerebral infarction) code is the principal diagnosis; once the acute phase has resolved and the patient is seen solely for residual deficits, the appropriate I69.3xx code(s) serve as the principal or additional diagnosis depending on the encounter reason.
💰 HCC Risk Adjustment
| HCC Model | Category | Label | Community Non-Dual Aged RAF |
|---|---|---|---|
| CMS-HCC V28 (PY2026) | None | Not HCC-Mapped | 0 |
| CMS-HCC V24 (legacy) | None | Not HCC-Mapped | 0 |
ICD-10 CM I69.314 does not map to any HCC category under CMS-HCC V28 for PY2026 and carries a RAF contribution of zero. The broader I69.x sequelae family is largely non-HCC-mapped under V28 with the exception of specific hemiplegia/hemiparesis codes (I69.35x) which do carry HCC mapping. The clinical and financial justification for coding I69.314 despite its zero RAF lies in quality measure capture, care coordination, rehabilitation authorization support, and documentation integrity — payers use diagnosis specificity to manage case complexity even when it does not generate an independent risk score. For Medicare Advantage patients, the acute I63.xx infarction code is the primary HCC capture vehicle; coders should confirm that the acute stroke code was submitted within the current plan year to ensure the stroke-related HCC is represented in the patient’s RAF profile.
🏥 MS-DRG Assignment
| DRG | Title | Trigger Condition |
|---|---|---|
| DRG 056 | Degenerative Nervous System Disorders with MCC | I69.314as principal + documented MCC |
| DRG 057 | Degenerative Nervous System Disorders without MCC | I69.314as principal, no qualifying MCC |
| DRG 064 | Intracranial Hemorrhage or Cerebral Infarction with MCC | When acute I63.xx is principal instead |
| DRG 065 | Intracranial Hemorrhage or Cerebral Infarction with CC | When acute I63.xx is principal instead |
| DRG 066 | Intracranial Hemorrhage or Cerebral Infarction without CC/MCC | When acute I63.xx is principal instead |
When I69.314 serves as the principal diagnosis (e.g., inpatient admission for post-stroke cognitive rehabilitation or neuropsychological evaluation), the case groups to MDC 01 DRG 056/057 based on the presence or absence of an MCC. The most important coding distinction in this DRG family is ensuring the correct principal diagnosis is assigned — I69.314 as principal is appropriate only when no new acute cerebrovascular event is occurring and the admission is solely to evaluate or manage the residual cognitive deficit. When an acute cerebral infarction (I63.xx) is the reason for the current admission, that code sequences as principal and drives DRG 064/065/066; I69.314 would only appear as additional in that scenario when it represents a pre-existing sequela from a prior, separate infarction. MCC triggers that elevate DRG 056 over 057 include severe sepsis (A41.9 + R65.20), acute respiratory failure (J96.00), and stage 4 pressure ulcers — query for and code these aggressively when documented to protect appropriate reimbursement.

🛠️ Commonly Associated CPT Codes
- 96116 — Neurobehavioral status examination, clinical assessment of thinking, reasoning, and judgment, first hour: This is the primary profee CPT for formal cognitive assessment by a neuropsychologist or physician; documentation must reflect evaluation of the specific cognitive domains including executive function, and is the gold-standard support for I69.314.
- 96132 — Neuropsychological testing evaluation services by psychologist or physician, first hour: Used when a licensed neuropsychologist performs and interprets a full neuropsychological battery including executive function testing (Trail Making B, COWAT, WCST); must be billed by the evaluating clinician and requires a written interpretation report.
- 97129 — Therapeutic interventions that focus on cognitive function, initial 15 minutes: Speech-language pathology cognitive rehabilitation targeting executive function deficits post-stroke; billed in 15-minute increments and requires documentation of functional goals tied to the deficit domain.
- 99233 — Subsequent hospital inpatient or observation care, high complexity: When the treating neurologist or physiatrist manages a post-stroke patient with multiple active cognitive sequelae, high-complexity MDM is generally supportable; document the number of conditions managed, data reviewed, and risk level explicitly.
- 90837 — Psychotherapy, 60 minutes: Applicable when post-stroke depression or behavioral dysregulation complicating the executive dysfunction is being managed with psychotherapy; billed by the treating psychologist or licensed therapist and should be paired with appropriate F32.x/F34.x depression codes.
NCCI Bundling Considerations
Neurobehavioral status examination (96116) and neuropsychological testing (96132) are considered distinct services — 96116 is performed by the evaluating physician/clinician whereas 96132 is a psychologist-level service — and NCCI edits limit same-day billing of these two codes without an appropriate modifier to prevent duplicate payment for the same service. Cognitive rehabilitation (97129/97130) billed alongside other speech-language pathology codes (92507, 97533) on the same date requires NCCI review, as bundling edits exist for same-session cognitive and communication treatment. Always confirm whether the evaluating clinician is a psychologist, neuropsychologist, physician, or SLP before assigning CPT codes, as scope-of-practice rules dictate which codes each provider type may bill.
🔬 ICD-10-PCS Crosswalk
- GZ3ZZZZ — Group psychotherapy: Used when inpatient group psychological/behavioral interventions are delivered for post-stroke cognitive rehabilitation or adjustment disorder; section G (Mental Health), root operation “Group Psychotherapy.”
- F07Z0ZZ — Speech treatment of brain using audiovisual equipment, no qualifier: SLP cognitive-linguistic treatment targeting executive function and communication in the post-stroke inpatient rehabilitation setting; coded under section F (Physical Rehabilitation and Diagnostic Audiology).
- GZ2ZZZZ — Biofeedback: Used when biofeedback-based neurocognitive rehabilitation is delivered for executive dysfunction in the inpatient psychiatric or rehab setting; section G, root operation “Biofeedback.”
- 00B30ZZ — Excision of cerebral ventricle, open approach: Not directly related to I69.314 but serves as a reference point — ICD-10-PCS neurosurgical procedures should only be linked to I69.314 in the context of a prior infarction where surgical intervention on residual pathology (e.g., post-infarction hydrocephalus) is being performed; confirm the operative indication explicitly.
💊 Coding Scenarios and Examples
Scenario 1 — Inpatient Rehabilitation Admission A 71-year-old male is admitted to inpatient rehab 6 weeks following a left middle cerebral artery (MCA) ischemic stroke. The PM&R attending documents “persistent executive function deficit with impaired planning and working memory, and right-sided hemiparesis, as sequelae of prior left MCA cerebral infarction.” Neuropsychology consultation documents dysexecutive syndrome on formal testing. Post-stroke depression is also documented and managed with medication adjustment.
- Correct coding (principal → additional): I69.314 (frontal lobe and executive function deficit — principal reason for rehab admission) → I69.351 (hemiplegia/hemiparesis following cerebral infarction, right dominant side) → F32.1 (major depressive disorder, moderate — CC)
- Sequencing: I69.314 as principal is appropriate as the condition chiefly responsible for this rehabilitation admission; I69.351 and F32.1 are additional. F32.1 may serve as a CC and elevate DRG to 056.
- CDI note: Query the attending to explicitly state both “executive function deficit” and “hemiparesis” as separate residual deficits from the prior infarction; generic language like “residual stroke deficits” is insufficient to support multiple specific I69.3xx codes.
Scenario 2 — Outpatient Neurology Follow-Up Documented in Inpatient Profee Note A 65-year-old female with history of right posterior frontal cerebral infarction 4 months ago presents for inpatient neurology evaluation for behavioral changes. Neurologist documents “executive dysfunction and cognitive social deficit following prior right frontal cerebral infarction” with new concern for post-stroke disinhibition and apathy. Neuropsychological testing confirms FAB score consistent with frontal dysfunction.
- Correct coding: I69.314 (frontal lobe and executive function deficit — primary reason for evaluation) → I69.315 (cognitive social or emotional deficit following cerebral infarction — separately documented)
- Sequencing: Both codes are additional if an inpatient admission is driven by these two post-stroke sequelae; if the encounter is solely for evaluation of these deficits, either may sequence first depending on the primary focus of the visit.
- CDI note: Ensure the neurologist’s note explicitly names each cognitive domain (executive AND social/emotional) — without domain-specific language, only one of these codes is supportable.
Scenario 3 — New Acute Stroke with Pre-Existing Executive Deficit A 78-year-old male with known prior left frontal lobe infarction (with documented executive dysfunction) is admitted acutely with new right hemispheric ischemic stroke confirmed on CT perfusion. He has a pre-existing executive function deficit from his prior stroke that remains active per the H&P.
- Correct coding: I63.50 (Cerebral infarction due to unspecified occlusion or stenosis of unspecified cerebral artery — acute; principal) → I69.314 (pre-existing executive function deficit from prior infarction — additional) → additional sequelae codes for prior deficits as documented
- Sequencing: The acute I63.xx code is always principal when a new cerebral infarction is the reason for admission; I69.314 is additional and represents the pre-existing residual deficit from a separate prior event. Do not use I69.314 as the code for deficits from the new acute infarction during the acute admission.
- CDI note: The H&P must clearly distinguish the pre-existing cognitive deficit (from the prior infarction) from any new neurological deficits attributable to the current acute event; this distinction is critical for sequencing accuracy and for correctly attributing deficits to the right event.
⚠️ Coding Pitfalls and Tips
- Never use I69.314during the active/acute cerebral infarction encounter. I69.314 is a sequela code — it is reserved for encounters after the acute event has resolved when only the residual deficit remains. During the acute infarction admission, code the active I63.xx code; I69.314 is only appropriate at subsequent encounters.
- Do not confuse I69.314with R41.844 (Frontal lobe and executive function deficit symptom code). R41.844 is a symptom code used when the etiology of the executive dysfunction has not been established. Once the provider has confirmed the deficit is attributable to a prior cerebral infarction, I69.314 replaces R41.844 per ICD-10-CM guideline I.B.4 (signs and symptoms integral to a confirmed diagnosis are not coded separately).
- Multiple I69.31x codes CAN and SHOULD be coded simultaneously when multiple cognitive domains are documented. Each I69.31x code in the family (attention, memory, visuospatial, psychomotor, executive, social/emotional) represents a distinct cognitive deficit that can coexist — do not use only one code when the record supports several.
- Z86.73 vs. I69.314is a binary decision. If the provider states “history of stroke, no residual deficits,” Z86.73 is correct and I69.314 must not be coded. If any residual deficit is documented and active, Z86.73 is no longer appropriate. Query the provider when ambiguity exists.
- I69.314has no RAF under V28 — but it still belongs in the record. Some coders skip non-HCC-mapped codes to reduce documentation burden; this is a mistake. I69.314 supports quality metrics, rehabilitation authorization, care coordination decisions, and audit defense. Code it every time it is documented and active.
- Traumatic brain injury executive deficits use a completely different code family. Post-TBI executive dysfunction sequences under S06.x with 7th character “S” for sequela — never use I69.314 for a TBI patient, even if the clinical presentation looks identical to post-stroke executive dysfunction.
