Dial Into Appropriate Cardiomyopathy Dx Code
Question: My cardiologist documented cardiomyopathy due to drugs and an external agent. Which ICD-10-CM code should I report on my claim? Florida Subscriber Answer: You should report I42.7 (Cardiomyopathy due to drug and external agent) for cardiomyopathy due to drugs and an external agent. Don’t miss: You should first code the poisoning due to drugs or toxin, if applicable, with codes T36- (Poisoning by, adverse effect of and underdosing of systemic antibiotics) through T65- (Toxic effect of other and unspecified substances), per ICD-10-CM. You should also report an additional code for adverse effect, if applicable, to identify the drug from categories T36- through T50- (Poisoning by, adverse effect of and underdosing of diuretics and other and unspecified drugs, medicaments and biological substances).
