COURSE IN EMERGENCY DEPARTMENT: The patient’s chest pain improved after the sublingual nitroglycerine and completely resolved with the Nitroglycerin Drip at 30 ug/Minute. He tolerated the TPA well. He was transferred to the CCU in a stable condition
10:40 PM Dr. ABC (cardiologist) apprised. He agrees with T PA per 90 minute protocol & IV nitroglycerin drip. He is to come see patient in the emergency department.
10:45 PM risks & benefits of TPA discussed with patient & his family. They agree with administration of TPA and are willing to accept the risks.
10:50 PM TPA started.
11:20 PM Dr. ABC present in emergency department assisting with patient care.
CBC: WBC 14.2, hematocrit 33.5, platelets 316
Chem 7: Na 142, potassium 4.5, chloride 102, CO2 22.6, BUN 15, creatinine 1.2, glucose 186
Serum Troponin I: 2.5
Chest x-ray: Lung fields clear. No cardiomegaly or other acute findings
EKG: Atrial fibrillation with Ventricular rate of 65. Acute inferior ischemic changes noted i.e. ST elevation III & aVF (refer to EKG multimedia).
Cardiac monitor: Sinus rhythm-atrial of fibrillation rate 60s-70s.
Heparin lock X. 2. Nasal cannula oxygen 3 liters/minute. Aspirin 5 grains chew & swallow. Nitroglycerin drip at 30 micrograms/minute. Cardiac monitor. TPA 90 minute protocol. Heparin IV 5000 unit bolus followed by 1000 units/hour.
IMPRESSION: Acute Inferior Myocardial Infarction in patient with family cardiac history. Nicotine dependence.
PLAN: Patient admitted to Coronary Care Unit under the care of Dr. ABC.
ICD-10-CM Code(s):         I21.19 ST elevation (STEMI) myocardial infarction involving other coronary artery of inferior wall
                                                 F17.210 Nicotine dependence, cigarettes, uncomplicated
                                                 Z82.49 Family history of ischemic heart disease and other disease of the circulatory system
Rationale:   The codes for acute myocardial infarction (MI) in ICD-10-CM identify the site, the temporal parameter (initial or subsequent), whether the myocardial infarction is an ST elevation or non-ST elevation infarction, and contributing factors. In this example, the documentation states the patient to have an MI of the inferior wall. In the diagnostic studies listed, the MI is further identified as an ST elevation MI. As this is the patient’s first presentation and no previous MI is documented, it is considered initial. The social history states that the patient is a current smoker at two packs per day. A family history of coronary artery disease is noted and should also be reported as the patient is diagnosed with a myocardial infarction.

    im so excited for ICD-10 to be implemented. . it looks easier and more detailed orientated to find the proper code for the job.

  2. Megan Wallace says:

    This example makes it look easy. The difficulty will be getting the physicians to document everything need for ICD-10

  3. Sami says:

    I’m still a coding student, so I’m not an expert, but shouldn’t the diabetes be coded as well?

  4. Diane says:

    I agree shouldn’t the diabetes be coded?

  5. Bethdreaux says:

    The patient is diabetic and has a prior history of coronary artery disease. Not only is he diabetic, but it looks like he has a personal history do CAD.
