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).
Why ICD-10 codes are important
Used for medical claim reporting in all healthcare settings, ICD-10-CM is a standardized classification system of diagnosis codes that represent conditions and diseases, related health problems, abnormal findings, signs and symptoms, injuries, external causes of injuries and diseases, and social circumstances.
(NSTEMI) is a common diagnosis in hospitalized patients. Type 2 has been reported up to 25% of cases of MI depending on the population studied. Type 2 NSTEMI is defined as myocardial ischemia resulting from mismatched myocardial oxygen supply and demand that is not related to unstable coronary artery disease (CAD).
Type 2 myocardial infarction (MI) is defined by a rise and fall of cardiac biomarkers and evidence of ischemia without unstable coronary artery disease (CAD), due to a mismatch in myocardial oxygen supply and demand. Myocardial injury is similar but does not meet clinical criteria for MI.

Acute myocardial infarction, unspecified I21. 9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM I21. 9 became effective on October 1, 2021.
The main causes of type-II MI were anemia (31%), sepsis (24%), and arrhythmia (17%). Patients with type-II MI tended to be older (75.6±12 vs. 63.8±13, p<0.0001), female majority (43.3% vs. 22.3%, p<0.0001), had more frequently impaired functional level (45.7% vs.
Patients who present with abdominal discomfort and shortness of breath may have their cardiac troponin level measured, which, if combined with other features such as ischemic ECG changes and symptoms, may lead to a type 2 MI diagnosis.
Treatment of type 2 MI is to treat the underlying condition and hence remove the cardiac insult. To adequately assess the prognosis and determine appropriate further treatment in patients with type 2 MI, information about whether the patient has (or is likely to have) significant underlying CAD is essential.
Type 2 MI is distinguished from myocardial injury without acute ischemia, for example, acute heart failure and myocarditis.

2022 ICD-10-CM Diagnosis Code I21: Acute myocardial infarction.
An MI is coded as acute for a period of four weeks following onset; after that, it is assigned code I25.2 (old MI). Codes in category I22 are also provided for a subsequent type 1 MI (STEMI or NSTEMI), defined as another MI occurring within four weeks of a previous (initial) MI. In this situation, a code from I21 is also assigned for the initial MI.
Type 1 is the classic spontaneous MI, primarily due to coronary artery disease (CAD) with atherosclerotic plaque rupture, ulceration, fissuring, erosion, or dissection causing intraluminal thrombosis. Occasionally type 1 occurs in the absence of CAD with spontaneous thrombosis of a coronary artery (particularly in women). Type 1 includes Q-wave infarction, ST-elevation MI, and non-ST elevation MI.
Old or healed Myocardial Infarctions not requiring further care may be assigned ICD-10 code I25.2 if supported by documentation in the chart.
Myocardial Infarction has defined six types of MI. The two most commonly encountered are type 1 (primarily due to CAD) and type 2 (primarily due to myocardial supply/demand mismatch). For these two types, MI is defined as myocardial necrosis identified by a rise and/or fall of cardiac biomarkers to or from a level greater than the 99th percentile of the upper reference limit.
There is always an underlying condition or disease process that causes the Type 2 MI. Ischemia means insufficient blood perfusion, and prolonged ischemia leads to infarction, i.e., cell death. When cells die and break down, they release their contents, including troponin, a heart-muscle protein.
Type 1 MI is myocardial necrosis, or cell death, caused by an anatomic blockage of blood flow for a prolonged period of time. This is usually due to atherosclerotic plaque and rupture or thrombosis, causing mechanical coronary artery obstruction. Type 2 MI is also cell death, but in a non-anatomic distribution due to generalized hypoperfusion, ...
It is a non sequitur to have a subsequent Type 2 MI. Type 2 MI is related to flogging a heart on the basis of some other condition, not a direct reflection of the heart’s intrinsic health (although Type 2 MIs are more likely to occur in older patients with underlying generalized heart disease), and it is limited to the index admission. If one survives septic shock with a Type 2 MI, one might follow up with a cardiologist to rule out coronary artery and heart disease – which might respond to chronic treatment, but not for long-term treatment of the Type 2 MI, per se.
However, Type 2 MI does not have the same course, prognosis, or treatment as Type 1 MI. Once the underlying condition is brought under control, the Type 2 MI resolves. Healthcare providers were gun-shy about calling out Type 2 MIs initially because the inability to code and separate out the condition caused them to fall out of the AMI Core Measures. Most facilities bypassed this problem by using “not indicated due to Type 2 MI” as an exclusion in their order set.
A second Type 1 MI can either be reinfarction in the same anatomic distribution, as an extension of the first MI, or a patient can have another Type 1 MI in a different vessel , with a different area of the heart being affected. Treatment of myocardial infarction has always been informed by the desire to prevent death, reinfarction, ...
Codes. I21 Acute myocardial infarction.
A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code ( I21) and the excluded code together.
A disorder characterized by gross necrosis of the myocardium; this is due to an interruption of blood supply to the area.
Did the patient have a MI, or was the physician only documenting that an episode of demand ischemia occurred? Anytime you feel that the documentation is unclear, you need to query the provider for clarification of the terms used for correct code assignment .
For example, a physician recently documented that a patient had elevated troponin, likely a Type 2 MI/demand ischemia in the setting of a hypertensive emergency. In this case, demand ischemia would be a CC, and Type 2 MI would affect the DRG assignment, but it wouldn’t add a CC/MCC.
Subclass of diabetes mellitus that is not insulin responsive or dependent; characterized initially by insulin resistance and hyperinsulinemia and eventually by glucose intolerance, hyperglycemia, and overt diabetes; type ii diabetes mellitus is no longer considered a disease exclusively found in adults; patients seldom develop ketosis but often exhibit obesity.
A subclass of diabetes mellitus that is not insulin-responsive or dependent (niddm). It is characterized initially by insulin resistance and hyperinsulinemia; and eventually by glucose intolerance; hyperglycemia; and overt diabetes. Type ii diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop ketosis but often exhibit obesity.
It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as E11. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
One of the problems providers have had with diagnosing Type 2 MI was that there was no unique code for a Type 2 MI until October 2017. This meant that every time a Type 2 MI was diagnosed, the patient was marked as having atherosclerotic heart disease, and the core measures were initiated. Last October, the code I21.A1, Myocardial infarction, Type 2, was added to ICD-10-CM.
If you note an abnormal troponin early and you are interacting with a provider verbally and concurrently, bring it to their attention. It is optimal to consider Type 2 MI early, and to diagnose or rule out subsequently. I would not formally query unless and until the condition declares itself.
Type 3 MI, which is cardiac death with symptoms of myocardial ischemia and suggestive EKG changes, but demise occurs before any biomarker trending can be demonstrated;
Myocardial infarction is a specific subset of myocardial injury. The definition of MI includes a rise and/or fall (depending on when the patient is encountered in the evolution of the MI) of a cardiac biomarker signifying cell death, with at least one value above the 99 th percentile upper reference limit (URL), plus some evidence of myocardial ischemia (be it symptoms, EKG or imaging evidence, or demonstration of a thrombus).
Acute myocardial infarction (MI) is the term for myocardial necrosis, or cell death, in a clinical setting, consistent with myocardial ischemia. “Ischemia” implies insufficient blood perfusion, and prolonged ischemia results in cell death.
Such is the case with troponin. In October 2012, the Third Universal Definition of Myocardial Infarction (TUDMI) was published by the American Heart Association, redefining myocardial infarction (MI).
There is always an underlying etiology. The implication of a Type 2 MI is that it portends a worse prognosis for the causative condition.
