The new codes are for describing the infusion of tixagevimab and cilgavimab monoclonal antibody (code XW023X7), and the infusion of other new technology monoclonal antibody (code XW023Y7).
The ICD-10-CM (International Classification of Diseases, Tenth Revision, Clinical Modification) is a system used by physicians and other healthcare providers to classify and code all diagnoses, symptoms and procedures recorded in conjunction with hospital care in the United States.

What is the correct ICD-10-CM code to report the External Cause? Your Answer: V80.010S The External cause code is used for each encounter for which the injury or condition is being treated.
How should this be coded? Answer: Assign 434.91 Occlusion of Cerebral arteries, cerebral artery occlusion, unspecified with cerebral infarction AND 431- intracerebral hemorrhage, for the description subacute ischemic right posterior parietal watershed infarct with small focus of subacute hemorrhage.
The subacute period after a stroke refers to the time when the decision to not employ thrombolytics is made up until two weeks after the stroke occurred. Family physicians are often involved in the subacute management of ischemic stroke.
Three main stages are used to describe the CT manifestations of stroke: acute (less than 24 hours), subacute (24 hours to 5 days) and chronic (weeks). 3. Acute stroke represents cytotoxic edema, and the changes can be subtle but are significant.
Strokes may be classified and dated thus: early hyperacute, a stroke that is 0–6 hours old; late hyperacute, a stroke that is 6–24 hours old; acute, 24 hours to 7 days; subacute, 1–3 weeks; and chronic, more than 3 weeks old (Tables 1, 2).
This type of stroke is caused by a blockage in an artery that supplies blood to the brain. The blockage reduces the blood flow and oxygen to the brain, leading to damage or death of brain cells.
Infarction or Ischaemic stroke are both names for a stroke caused by a blockage in a blood vessel in the brain. This is the most common type of stroke. Blockages can be caused by a blood clot (Thrombosis) forming around fatty deposits in the blood vessels of the brain.
Evolving strokes occur when a still-functioning yet ischemic (deprived of blood) area of the brain deteriorates further and eventually becomes less or non-functional, ultimately developing into an infarct.
Stroke occurs when decreased blood flow to the brain results in cell death (infarct/necrosis) There are two main types of stroke: ischemic (most common) due to lack of blood flow from thrombosis, embolism, systemic hypoperfusion, or cerebral venous sinus thrombosis, and hemorrhagic, due to bleeding.
Nonhemorrhagic infarctions, otherwise called ischemic infarctions, are the result of the acute interruption of blood flow to an area within the brain. The usual cause for a nonhemorrhagic infarction is the occlusion of an intracranial artery by a thromboembolism.
The clinical staging of stroke (Cramer, 2008; Rehme et al., 2012; Zhao et al., 2014) is generally accepted as follows: the first 2 weeks are defined as the acute stage; 3–11 weeks post-stroke is termed the subacute stage in which most changes occur; 12–24 weeks post-stroke is the early chronic stage; and more than 24 ...
The initial phase is called the acute phase and lasts for about 2 weeks after the onset of the lesion. The second phase is the subacute phase, and this usually lasts up to 6 months after onset. Finally, the chronic phase begins months to years after stroke, and it may continue for the remainder of the person's life.
Subacute care: 4 to 14 days. An injury in this stage is beyond acute but still “somewhat” or “bordering on” acute.
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.
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.
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.
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.
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.
