Expertly Code This Eczema Case
Question: I’m unsure which ICD-10-CM code is appropriate based on the following notes from a recent patient visit at our pediatric office. Any guidance is appreciated: A 5-year-old patient came in with their parents, and they report the child has been excessively scratching, mostly at night. Symptoms began about two weeks ago with no known trigger. There is no fever or loss of appetite. Patient has no known allergies and is up-to-date on immunizations. During the physical exam, dry red patches were noted on both arms and behind the knees with no signs of infection. All other systems appear normal. Condition appears to be atopic dermatitis. Prescribing a steroid cream to reduce inflammation and itching. Will follow up with patient in two weeks. How should I code this encounter? Kentucky Subscriber Answer: Atopic dermatitis, often referred to as eczema, is a chronic condition characterized by dry, inflamed, and itchy skin. Kids who suffer from eczema tend to have more delicate skin compared to other children without the condition. To find the correct ICD-10-CM code, look to the L20- (Atopic dermatitis) code family. Because there is no known trigger for this patient’s condition, L20.9 (Atopic dermatitis, unspecified) will be most appropriate in this case. If this had been an obvious allergic reaction to laundry detergent or another outside cause, you would choose L20.84 (Intrinsic (allergic) eczema). Lindsey Bush, BA, MA, CPC, Production Editor, AAPC
