The monitoring of coronary arterial pressure using a percutaneous approach is reported with which code?

The correct code for the monitoring of coronary arterial pressure using a percutaneous approach is 4A133BC. In ICD-10-PCS, the format of the codes provides specific information regarding the procedure performed.

The first character '4' indicates the section for procedures on the heart and great vessels. The second character 'A' signifies that the procedure is specifically related to the measurement of pressures. The third character '1' denotes that this applies to a percutaneous approach, allowing for the proper classification of the method used.

The fourth character, which in this case is '3', refers to the specific monitoring of arterial pressure. The fifth character is 'B', which specifies the body part involved—in this case, the coronary arteries. The final character 'C' represents the specific type of procedure, which for coronary arterial pressure monitoring via a percutaneous approach, aligns perfectly with the intended action.

This detailed breakdown of each character reveals why 4A133BC is the most appropriate choice for this procedure.
