CHAPTER 32
Measurement and Monitoring Section

3. Measurement and Monitoring Section
The fifth section within ICD-10-PCS is the Measurement and Monitoring section.
The character 1 value for the Measurement and Monitoring section is 4.

4. Character 2—Body System
The value of character 2, body system, has
two values for the Measurement and
Monitoring section.
A—Physiological systems
B—Physiological devices

5. Character 3—Root Operations
For the Measurement and Monitoring
Section, there are two root operations used:
Measurement—Value of 0
Monitoring—Value of 1

6. Root Operation Definitions
Measurement—Determining the level of a physiological or physical function at a point in time
Monitoring—Determining the level of a physiological or physical function repetitively over a period of time

7. Body System/Region—Character 4
Character 4 in the Measurement and
Monitoring section indicates body system
that is being measured or monitored.
The values vary according to each table but
identify a body system.

8. Approach—Character 5 There are six approach values for the
Measurement and Monitoring section. Use
varies according to each table:
0—Open
3—Percutaneous
4—Percutaneous endoscopic

9. Additional Approach Values
7—Via natural or artificial opening
8—Via natural or artificial opening endoscopic
X—External

10. Character 6—Function For the Measurement and Placement
section the sixth character indicates the
physiological or physical function being
measured or monitored.

11. Additional Code Assignment
If a device used for measurement and
monitoring is inserted and left in the body,
then the insertion of the device is coded as a
separate procedure from the Medical and Surgical Section.

12. Character 7—Qualifiers
For the Measurement and Monitoring
section, the qualifier value varies according to the table that is being used.
The specific qualifier values further specify the body part of a variation of the procedure performed.

13. Key Points to Remember
The first character value for the Measurement and Monitoring section is 4.
The second character value for the Measurement and Monitoring section has two possible values.
The third character value has two possible values indicating the root operation.

14. Additional Points
The fourth character value in the Measurement and Monitoring section varies according to the physiological system or physiological device.
The fifth character value in the Measurement and Monitoring section has six possible values.

15. Final Points
For the sixth character in the Measurement and Monitoring section, the physiological or physical function being measured or monitored is identified.
For the seventh character value for the Measurement and Monitoring section, the value indicates the specific body part or variation of the procedure performed.
