Which of the following would not be a valid code for measuring blood pressure?

The chosen code, 4A060XY, is characterized as not valid for measuring blood pressure based on the conventions set forth in the ICD-10-PCS coding guidelines. In ICD-10-PCS, codes are structured to represent specific types of procedures, and blood pressure measurement is categorized within a certain range of codes.

The first part of the code, '4A', signifies the section for measurement. Codes starting with '4A' are typically used to indicate various measurement procedures; however, the subsequent characters determine the specific procedure performed.

In this case, for blood pressure measurement, the appropriate code would generally contain the character 'B' in the last character, signifying a specific function identified for hemodynamic measurement procedures including blood pressure monitoring. The correct codes for blood pressure measurement would typically include 'BZ', 'AX', or 'CX' at their conclusion as valid designators.

The other codes provided (including 'BZ', 'AX', and 'CX') align with recognized measurement procedures, allowing them to accurately document and classify the measurement of blood pressure. Therefore, the provided response indicates that '4A060XY' does not fit the identified criteria for valid codes in this context.
