What is the term for a stroke that occurs when there is disruption of blood flow to brain tissue?

stroke occurs when there is disruption of blood flow to brain tissue, this leads to ischemia (deprivation of oxygen) and potentially infarction (dysfunctional scar tissue). Strokes can be either hemorrhagic, or embolic/thrombotic. Hemorrhagic strokes occur as a result of a ruptured cerebral blood vessel. Embolic/thrombic strokes occur as a result of an obstructed cerebral vessel.

How accurate is the ICD-9 code for stroke?

Computerized databases such as Medicare claims files and hospital administrative records are increasingly being used to identify patients with acute stroke for epidemiological, quality of care, and cost studies. 123 These databases rely on patient diagnoses as classified according to the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM). However, the accuracy of ICD-9-CM coding for the identification of incident strokes can be poor. For example, separate community-based studies in Rochester, Minnesota, and Cincinnati, Ohio, found that only 46% to 47% of patients with a primary diagnosis code of 430 to 438 (Table 1) had an incident stroke. 34 Other investigators have found that limiting the identifying ICD-9-CM code to the primary position in administrative databases increased the proportion of patients accurately classified as having a stroke on subsequent review of their medical records. 5 In agreement with other work, this study also found that the accuracy of the ICD-9-CM classification depended on the specific code that was used. Only 15% of patients with code 433 were symptomatic for the index hospital admission. In contrast, 85% of patients with code 434 and 77% of those with code 436 had ischemic strokes. Based on these data, it is apparent that if a study intends to identify all patients in a given setting with an acute stroke based on ICD-9-CM codes, discharge summary review would be required to eliminate the high proportion of nonstroke cases. However, if the goal of a study is to follow trends or patterns of care, then identification of subpopulations with a high likelihood of having stroke would be advantageous because doing so could eliminate the need for extensive review of patients’ medical records.

What is the ICD-9 code for stenosis of precerebral arteries?

Methods —Available hospital charts for all patients discharged from a single hospital between May 1995 and June 1997 with ICD-9-CM codes 433 (occlusion and stenosis of precerebral arteries), 434 (occlusion of cerebral arteries), or 436 (acute but ill-defined cerebrovascular disease) listed in the first position were reviewed. The primary discharge diagnosis was verified, and a presumed stroke subtype was assigned on the basis of information provided in the medical record.

How accurate are modifier codes?

Approximately 50% to 60% of patients given codes indicating unspecified causes for stroke had an etiology established during the hospitalization as reflected in their discharge summaries. Although discharge coding is not typically done by neurologists (or physicians in general), accuracy may not necessarily be improved with further training of the coders. One study presented a series of case scenarios to a group of neurologists who were asked to assign specific discharge ICD-9 codes (which included a variety of modifier codes). 7 The chance corrected interobserver reliability of the classifications (kappa score) was 0.38, indicating only fair levels of agreement among the raters. 8

What is the purpose of the ICD-9 code?

Background and Purpose —Discharge ICD-9-CM ( International Classification of Diseases, 9th Revision, Clinical Modification) codes have been used to identify patients with acute stroke for epidemiological, quality of care, and cost studies. The aim of this study was to determine if the accuracy of the primary ICD-9-CM codes for ischemic stroke is improved by modifier codes and how specific codes reflect stroke subtype diagnoses.

Why is it beneficial to identify subpopulations with a high likelihood of having stroke?

However, if the goal of a study is to follow trends or patterns of care, then identification of subpopulations with a high likelihood of having stroke would be advantageous because doing so could eliminate the need for extensive review of patients’ medical records.

What is the ICD-10 code for stroke?

In ICD-10 CM, code category I63 should be utilized when the medical documentation indicates that an infarction or stroke has occurred. Coding of sequelae of stroke and infarction also demands a level of detail often missing in medical records. There are specific codes which indicate the cause of the infarction, such as embolism or thrombosis, as well as the specific affected arteries. The sixth digit provides additional information which designates the affected side when applicable.

How to code a stroke?

Seek answers to two questions when coding a stroke, infarction, or hemorrhage. First, ask if the cerebral event is acute, or emergent. Second, find in the medical record details of the site and the site, laterality, and type of stroke or infarction. Medical record documentation should clearly specify the cause-and-effect relationship between the medical intervention and the cerebrovascular accident in order to assign a code for an intraoperative or postprocedural cerebrovascular accident.

What is Z86.73?

If a patient has a history of a past cerebrovascular event and has no residual sequelae, report Z86.73 Personal history of transient ischemic attack (TIA ), and cerebral infarction without residual deficits.

What is the ICD-10 code for cerebral infarction?

The patient is admitted into hospital and diagnosed with cerebral infarction, unspecified ( ICD-10 code I63.9). At the 3-week post-discharge follow-up appointment for the cerebral infarction, the office visit note states the patient had a stroke and has a residual deficit of hemiplegia, affecting the right dominant side.

What are the risk factors for stroke?

Also code any documented atrial fibrillation, CAD, diabetes, or hypertension as these comorbidities are stroke risk factors.

When to report neurological deficits?

Report any and all neurological deficits of a cerebrovascular accident that are exhibited anytime during a hospitalization, even if the deficits resolve before the patient is released from the hospital.

Can a CT scan be used to report a stroke?

If the provider is not specific in recording the site of a stroke or infarction, it is permissible for coders to use the accompanying CT scans or other radiological reports to report the specific anatomic site.

What is the code for cerebral infarction?

While the majority of stroke diagnoses outside of the diagnostic radiology setting will not include enough supplementary information to code beyond I63.9 Cerebral infarction, unspecified, you should be prepared if, and when, the clinical encounter presents itself.

When is a stroke alert included in a diagnosis?

A stroke alert may be included as a supplementary diagnosis when the patient’s signs and symptoms are indicative of a possible stroke. However, the impression of the dictation report will have final say as to whether a stroke is revealed in the imaging scan.

What is a TIA in coding?

While there’s a clear-cut diagnosis (G45.9 Transient cerebral ischemic attack, unspecified) for a TIA, it’s often the surrounding speculative documentation that leads you to question the original diagnosis. While a TIA is often referred to as a “mini stroke,” from an ICD-10-CM coding perspective, it’s important to keep the two diagnoses entirely separate.

What is the first scenario for cerebral infarction?

This could yield an indication exclusively involving signs and symptoms, or it could offer a more straightforward diagnosis of stroke or stroke alert. If the indication states “stroke,” and the scan does not reveal a cerebral infarction, send the report back to the provider for an addendum.

How long does a stroke last?

As defined by the NCHS, a disease is to be considered chronic if its symptoms last more than three months. Formulating the series of steps from which a hyperacute stroke becomes chronic is not as straightforward — in part because no universal set of guidelines exists to help elaborate on those distinctions.

Can a CT scan show a stroke?

This second scenario will only occur if you’re coding an imaging study on the cerebral arteries, such as a magnetic resonance angiography (MRA) or computed tomography angiography (CTA). That’s because angiographies, or arteriograms, image the perfusion of the cerebral arteries. A traditional computed tomography (CT) scan or magnetic resonance imaging (MRI) scan evaluates the parenchyma of the brain. These scans will show the result of an occluded artery (i.e., stroke), but not the occlusion itself. This means that if you’re working on a traditional MRI or CT scan of the brain, you don’t need to be on the lookout for any underlying embolism, occlusion, stenosis, or thrombosis diagnoses.

Can you code TIA without a diagnosis?

If not, there’s a possibility that the patient’s symptoms are the result of a TIA, but without a definitive TIA diagnosis, you should code only the signs and symptoms. Coder’s note: A TIA diagnosis, unlike a stroke diagnosis, can be coded from the indication.
