When a patient is seen with cellulitis caused by a burn treated a week ago, which condition would be the first listed code?

• A. Burn Wound
• B. Cellulitis
• C. Sepsis
• D. Infection of the Skin

Answer: (B)

The main idea is to list the active problem driving the visit as the first code. In this scenario, the patient is seen for cellulitis, which is the current infection prompting treatment during this encounter. The burn from a week ago is a prior event, not the reason for the present visit, so it belongs as a secondary or historical condition if documented. Because cellulitis is the active issue being addressed now, it should be the first-listed diagnosis. The burn, while related, doesn’t drive the encounter unless documentation shows the visit is specifically for burn care or the burn is causing a current, separate problem. Sepsis would only be coded first if there were documented systemic infection, which isn’t indicated here. “Infection of the skin” is too nonspecific when a precise diagnosis of cellulitis is available. So the best choice is the cellulitis code because it directly represents the condition prompting care at this visit.
