Myocardial Infarction

in Clinical & Coding
According to the I10 guidelines an MI can be coded from the I21 category if it is equal to or less than 4 weeks and the patient requires continued care.  We have had MI cases that were readmitted within 30 days with a different PDX and our coders are coding the MI as an MCC merely because they patient was on a betablocker/ACE.  As CDI we don't believe this is accurate; can you give us some direction as to further educate our coders....or maybe this is legit and we are incorrect.

    We code as your coders do based on the Guidelines. 

    ICD-10-CM Official Guidelines for Coding and Reporting

    9. Chapter 9: Diseases of Circulatory System (I00-I99)

    e. Acute myocardial infarction (AMI)


    For encounters occurring while the myocardial infarction is equal to, or less than, four weeks old, including transfers to another acute setting or a postacute setting, and the patient requires continued care for the myocardial infarction, codes from category I21 may continue to be reported.

    I think the answer may be in the statement "requires continued care."  I am not certain it is to be interpreted that continued care is taking a beta blocker or ACE.  If the patient was re-admitted, even within the 4 weeks, from home to the hospital, then the care for this MI has not been continuous.  Our system would interpret continued care as hospital-rehab-SNF-hospital- skilled care to skilled care without a discharge to home.

    I would consider what the doctor would be thinking about in a patient that just had an MI. Would he be doing extra monitoring (EKG, VS, Tele, adjustment of meds, etc) because of concern for the recent MI? Then I would count it. If the patient came in for a completely unrelated condition, that does not have an affect on cardiac system, then no. Frankly I would lean toward using it more often than not. It helps if the MD writes what he is thinking as he orders tests, etc.

    We sent this question to coding clinic and they declined to answer further stating the issue is currently under review by the Editorial Advisory Board for Coding Clinic (5/11/16). Following resolution by the EAB, we should receive a definitive response.

    The guideline does not say anything about the MI within 4 weeks of admission being related to the admit diagnosis.  I think that is making an assumption about the meaning of the guideline.  I also think that 'continue care' is not the same as 'continuous care'.  The guideline does not say the patient needs to be under 'continuous' care.

    Is this right??  Patient admitted with upper extremity swelling -> ruled in DVT/Cellulitis -> pt had a recent STEMI (with in 28 days) -> DRG goes to 280.  Why does it still drive the DRG even though it isn't what brought the patient back to the hospital?  Thanks
