What is the first step in assigning a diagnosis code according to the guidelines?

• A. Abstract diagnoses from provider documentation
• B. Verify the patient age
• C. Use the simplest code
• D. Use the highest numeric code

Answer: (A)

The first step is to capture exactly what the provider documented as the patient’s diagnoses from the clinical notes and problem list. Abstracting those diagnoses from the chart gives you the precise conditions you need to code and sets up accurate, compliant coding. Without pulling the provider’s documented diagnoses, you risk coding something that wasn’t diagnosed or missing a condition that was, which can lead to incorrect codes and downstream problems. Verifying the patient’s age matters for ensuring the right codes are used, since some diagnoses are age-specific, but it isn’t the starting action for selecting codes. Similarly, choosing the simplest code goes against the goal of accuracy and specificity—codes should reflect the most precise diagnosis supported by the documentation. The idea of using the highest numeric code isn’t a valid rule in coding practice, as the correct code is determined by the documented condition and its specificity, not by its numerical value.
