Explanation
When there are comparative contrasting diagnoses supported by clinical criteria, the correct action is to code both diagnoses, as long as they are not mutually exclusive. Comparative contrasting diagnoses are those that are considered as possible alternatives or differentials for the patient's condition, such as pneumonia versus bronchitis, or appendicitis versus diverticulitis. Coding both diagnoses will capture the clinical uncertainty and complexity of the case, and will allow for accurate reporting and reimbursement. References: :
