The 2021 edition of ICD-10-CM I25.2 became effective on October 1, 2020. This is the American ICD-10-CM version of I25.2 - other international versions of ICD-10 I25.2 may differ. Past myocardial infarction diagnosed by ECG or other investigation, but currently presenting no symptoms
Sequencing of type 2 acute MI or the underlying cause is dependent on the circumstances of admission. When a type 2 acute MI code is described as NSTEMI or STEMI, only assign code I21.A1. Codes I21.01-I21.4 should only be assigned for type 1 acute MIs.
I21.A1 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2019 edition of ICD-10-CM I21.A1 became effective on October 1, 2018.
Aborted myocardial infarction is defined by major, i.e. over 50%, ST-segment resolution of the initial ST-segment elevation on the presenting ECG indicative of transmural myocardial ischaemia and a lack of a subsequent enzyme rise more than twice the upper normal limit of creatine kinase.
tPA may significantly improve symptoms, causing the physician to document “aborted CVA.” According to coding directives, an aborted CVA is assigned to code 434.91. Since tPA must be administered quickly, it is usually given at a community hospital emergency department (ED).
ICD-10 code I21. 9 for Acute myocardial infarction, unspecified is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
myocardial infarction: old (I25. 2) specified as chronic or with a stated duration of more than 4 weeks (more than 28 days) from onset (I25.
ICD-10 code: I63. 9 Cerebral infarction, unspecified.

History of codes is acceptable on any medical record regardless of the reason for visit. ❖ Myocardial Infarction (MI) o Acute Myocardial Infarction: A new MI is considered acute from onset up to 4 weeks post MI.
Acute Myocardial Infarction (heart attack) Acute myocardial infarction, also known as a heart attack, is a life-threatening condition that occurs when blood flow to the heart muscle is abruptly cut off, causing tissue damage. This is usually the result of a blockage in one or more of the coronary arteries.

ICD-10-CM Code for Complete or unspecified spontaneous abortion without complication O03. 9.
When an induced abortion is performed by dilating the cervix and performing sharp and/or suction curettage, use CPT code 59840 for reported such procedures. If the cervix is dilated and the uterus mechanically evacuated, code 59841 is reported.
This legal definition may determine which CPT codes are selected: abortion (59812-59857) or delivery (59400-59515)....Medical Abortion.Possible CodeDescription59855-59857By suppositories before 20 weeksE/M CodeSpontaneous/Other Medical Abortion before 20 weeks3 more rows

Codes. I21 Acute myocardial infarction.
A disorder characterized by gross necrosis of the myocardium; this is due to an interruption of blood supply to the area.
A blockage that is not treated within a few hours causes the affected heart muscle to die. Gross necrosis of the myocardium, as a result of interruption of the blood supply to the area, as in coronary thrombosis. Gross necrosis of the myocardium, as a result of interruption of the blood supply to the area.
In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere.". Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code.
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.
ACS: “acute coronary syndrome” is a concept that includes patients with STEMI, NSTEMI, or unstable angina
Answer: “STEMI” and “NSTEMI” are EKG descriptions and not formal clinical classifications of MI like types 1-5.
Answer: we feel that to defend against a denial, in a patient with all cTns above the URL of normal, the patient ought to have >20% change. Here is the math:
Coding Clinic, 2nd Quarter 2001, Pages 7-8 instructs unstable angina would be reported as the principal diagnosis (Note: if CAD is determined to be present and documented, then coding rules would require selection of CAD, and not unstable angina, as the PDx with unstable angina as a SDx).
In this case the change is significant, and an acute MI is supported by the presence of acute myocardial injury (cTn changes) that appears to be due to acute myocardial ischemia (as evidenced by the EKG changes).
Answer: in patients who survive, isolated troponin changes do not validate any type of MI, including silent MIs. In such cases, there must still be (along with the significant troponin change) clinical evidence to support acute myocardial ischemia. This can be evidenced by any one of the following:
The 4th Universal Definition paper, however, does not limit ACS to apply just only type 1 AMI. Therefore, “ no ACS” would exclude unstable angina and any type of MI, including a type 2 MI.
Use a code from category I22 in conjunction with a code from category I21 Acute myocardial infarction.
If a type 1 NSTEMI evolves to a STEMI, assign the STEMI code. If a type 1 STEMI converts to a NSTEMI due to thrombolytic therapy, it is still coded as STEMI.
Use a code from category I22 Subsequent ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction when a patient who has suffered a type 1 or unspecified acute MI has a new acute MI within the four-week time frame of the initial acute MI.
There are other causes, as well, which may reduce the blood supply to the myocardium such as spasm of coronary artery, some infections, high fever, and complication of certain procedures (e.g., coronary artery bypass grafting (CABG)).
The heart muscles require oxygen, glucose, and other nutrients to survive and to work. These elements are supplied through the blood that is pumped through the body by the heart muscle (myocardium). The blood vessels supplying the myocardium are known as coronary vessels.
Infarction means death of a tissue or necrosis. Acute MI means death of the tissues of the heart muscle. The heart pumps blood through the body in a cyclic manner by powerful contraction and relaxation of the heart muscle. The heart muscles require oxygen, glucose, and other nutrients to survive and to work.
