SUBJECT: ACS 0002 Additional diagnoses and alteration to treatment

Q: 


NOT APPLICABLE TO NEW ZEALAND
Does a condition meet the criteria in ACS 0002 Additional diagnoses when the medication to treat the condition has been altered to manage an adverse effect or another condition, as in the following scenarios? 

1. 
   Principal diagnosis of acute on chronic renal failure secondary to frusemide, with a past history of congestive cardiac failure treated with frusemide 80mg BD. Dose of frusemide was decreased to 40mg BD.
   

1. 
   Principal diagnosis of aspirin induced ulcers throughout upper gastrointestinal tract, with a past history of atrial fibrillation for which the patient had been commenced on aspirin. Aspirin was withheld for two days, and the patient was commenced on medication to treat the ulcers.
   

A:

Based on the limited information in the scenarios described, the conditions listed in the past history/background (congestive cardiac failure and atrial fibrillation) where medication to treat these conditions has been altered should be coded, as per the criteria in ACS 0002 Additional diagnoses; specifically dot point 1, ‘commencement, alteration or adjustment of therapeutic treatment’.
