How should code sequencing be performed when a disease is diagnosed and symptoms are present?

• A. If a disease is diagnosed, code the disease first; code signs/symptoms only if the disease is not diagnosed or if the symptom is the reason for the encounter
• B. Always code the symptom
• C. Code the symptom first
• D. Always code the highest-cost code first

Answer: (A)

When a disease is diagnosed, coding should reflect the primary condition first, with signs and symptoms added only as appropriate. The guidelines require listing the disease or diagnosis first, and then codes for signs or symptoms if they are not integral to the diagnosed condition or if the symptom is the reason for the encounter. So, if a disease is diagnosed and symptoms are present, the correct approach is to code the disease first. Add signs or symptoms only if the disease isn’t diagnosed or if the symptom is the reason the patient sought care. This sequencing ensures the main condition is identified as the primary diagnosis, with symptoms captured as secondary information when they are not part of the diagnosed disease. For example, if a patient has a diagnosed pneumonia and also has a fever, you would code the pneumonia first. You would code the fever only if it’s being documented as a separate reason for the visit or if it’s not considered an inherent part of the pneumonia.
