acute or subacute myocarditis ( I40 .-) Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.
Hypertension with Heart Disease: Hypertension with heart conditions classified to I50.- or I51.4- I51.9, should be assigned to a code from category I11, Hypertensive heart disease. An additional code from category I50, Heart failure, should be reported to identify the type of heart failure in those patients with heart failure.

First, in order to have a subsequent MI, there must first be an acute MI that has occurred in the preceding 28 days (not 30 days). Second, codes from category I22 should ONLY be applied if both the initial and subsequent MIs are type 1 MIs (coronary involvement, NSTEMI/STEMI) or unspecified.

Example of hypertension and heart involvement: For this patient, CHF and hypertension would be coded as code I11. 0, Hypertensive heart disease with heart failure since the causal relationship is assumed due to the word “with” following the main term in the Alphabetic Index under hypertension.
If hypertension, heart failure and chronic kidney disease are all documented, use a combination code from category I13 — hypertensive heart and chronic kidney disease. These are just a few examples of conditions that have an assumed causal relationship in ICD-10-CM.

Myo cardial Infarction:�Dont Skip a Beat in Dx Coding
Use a code from category I22 in conjunction with a code from category I21 Acute myocardial infarction.
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.
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)).
Coronary circulation. The major cause of MI is atherosclerosis — plaque formed in the coronary artery, reducing the lumen of the artery and obstructing blood flow. Plaques can become unstable, rupture, and promote the formation of a blood clot in an artery; this can occur in minutes.
Type 2 MI, due to demand ischemia or secondary to ischemic balance, is assigned to code I21.A1 with a code for the underlying cause.
The most common symptom of MI is chest pain, which may radiate to the left arm, neck, lower jaw, and back. Other symptoms include shortness of breath, palpitations, lightheadedness, fainting, nausea, and vomiting.#N #Along with the clinical signs and symptoms, diagnostic tests used to detect MI include:
Hypertensive Heart and Chronic Kidney Disease: The codes in category I13, Hypertensive heart and chronic kidney disease, are combination codes that include hypertension, heart disease and chronic kidney disease, and should be used when there is hypertension with both heart and kidney involvement. If heart failure is present, an additional code ...
When assigning diagnosis codes for hypertension (HTN), there is an presumed causal relationship between hypertension and heart involvement, and between hypertension and kidney involvement. The ICD-10-CM Official Guidelines for Coding and Reporting (I.C.9) instruct, “These conditions should be coded as related even in the absence of provider documentation explicitly linking them, unless the documentation clearly states the conditions are unrelated.” The Guidelines further specify:
CKD should not be coded as hypertensive if the physician has specifically documented a different cause. The appropriate code from category N18 should be used as a secondary code with a code from category I12 to identify the stage of chronic kidney disease.
