Understanding ICD-10-PCS Table 4A0 (Measurement of Physiological Systems)

The ICD-10-PCS (Procedure Coding System) is utilized in U.S. healthcare settings for reporting inpatient hospital procedures. Table 4A0 belongs to the Measurement and Monitoring section, specifically addressing procedures within the Physiological Systems body system, and focuses on the root operation of Measurement.

A complete 7-character ICD-10-PCS code from this table is constructed as follows:

  • Character 1 (Section): 4 - Measurement and Monitoring
  • Character 2 (Body System): A - Physiological Systems
  • Character 3 (Root Operation): 0 - Measurement
  • Character 4 (Character 4): Specifies the exact body part involved in the measurement.
  • Character 5 (Character 5): Defines the technique (e.g., Open, Percutaneous) used to reach the procedure site.
  • Character 6 (Character 6): Indicates if a device was used during the measurement and its type.
  • Character 7 (Character 7): Provides additional specific information or clarifies the procedure.

Accurate assignment of each character based on the operative report and the detailed definitions within the ICD-10-PCS system is essential for correct coding. This page lists all valid options and combinations for table 4A0 according to the 2025 ICD-10-PCS guidelines.
