Convert to ICD-9 General Equivalence Map
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.
- 410.91 - AMI NOS, initial (approximate) Approximate Flag
The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
- Subsequent myocardial infarction
- Subsequent ST segment elevation myocardial infarction

Information for Patients
Also called: MI, Myocardial infarction
Each year over a million people in the U.S. have a heart attack. About half of them die. Many people have permanent heart damage or die because they don't get help immediately. It's important to know the symptoms of a heart attack and call 9-1-1 if someone is having them. Those symptoms include
- Chest discomfort - pressure, squeezing, or pain
- Shortness of breath
- Discomfort in the upper body - arms, shoulder, neck, back
- Nausea, vomiting, dizziness, lightheadedness, sweating
These symptoms can sometimes be different in women.
What exactly is a heart attack? Most heart attacks happen when a clot in the coronary artery blocks the supply of blood and oxygen to the heart. Often this leads to an irregular heartbeat - called an arrhythmia - that causes a severe decrease in the pumping function of the heart. A blockage that is not treated within a few hours causes the affected heart muscle to die.
