Block 33 on AF Form 560 records which data?

• A. Block 33, Primary admission diagnosis
• B. Block 38, Diagnosis-Procedures
• C. Block 40, Administrative data
• D. Block 41, Disposition

Answer: (A)

Block 33 records the primary admission diagnosis—the main condition that led to the patient’s hospitalization. This is the chief reason the patient was admitted, identified at the time of admission and used for coding and statistical purposes. It’s distinct from other data in the form, such as secondary diagnoses or procedures, which are captured in different blocks.

Understanding the layout helps: this block is specifically for the principal diagnosis, not a list of all conditions the patient has or the procedures performed. Other blocks handle those aspects—one block gathers secondary diagnoses and any procedures, another holds administrative details like identifiers and dates, and another records the disposition or outcome of the admission. So Block 33 is the place where the main reason for the admission is recorded, separate from the rest of the clinical and administrative information.
