1. Blood pres- A blood pressure measurement is an external method of recording systolic and
sure measure- diastolic blood pressures using the brachial artery (in the left or right arm), a
ment, left arm sphygmomanometer, and a stethoscope. It determines the amount of pressure the
patient's blood is exerting against arterial walls when the heart beats and at rest,
respectively. Root operation Measurement is defined as determining the level of a
physiological or physical function at a point in time.
Go to ICD-10-PCS index main term Blood pressure see Measurement, Arterial 4A03.
Then, go to ICD-10-PCS index main term Measurement and subterms Arterial, Pres-
sure, Peripheral 4A03. In ICD-10-PCS table 4A0, select fourth-character 3 (Arterial),
fifth-character X (External), sixth-character B (Pressure), and seventh-character 1
(Peripheral).
2. Temperature Temperature monitoring is performed externally (e.g., forehead) using a digital
monitoring, or glass thermometer, via natural opening (e.g., ear, mouth, rectum) using an ap-
forehead propriate thermometer, or via artificial opening (e.g., subcutaneous) using needle
thermocouples. Root operation Monitoring is defined as determining the level of a
physiological or physical function repetitively over a period of time.
Go to ICD-10-PCS index main term Monitoring and subterm Temperature 4A1Z. In
ICD-10-PCS table 4A1, select fourth-character Z (None), fifth-character X (External),
sixth-character K (Temperature), and seventh-character Z (No Qualifier).
3. Cardiac out- Cardiac output is the volume of blood ejected by each of the heart's ventricles per
put monitoring minute, and it is the product of stroke volume and heart rate.
via percutaneous Go to ICD-10-PCS index main term Monitoring and subterms Cardiac and Output
pulmonary artery 4A12. In ICD-10-PCS table 4A1, select fourth-character 2 (Cardiac), fifth-character 3
catheter (Percutaneous), sixth-character 9 (Output), and seventh-character Z (No Qualifier).
4. Electromyogram An electromyogram (EMG) is a common procedure name that measures the elec-
trical activity in muscles. Root operation Measurement is defined as determining
the level of a physiological or physical function at a point in time.
Go to ICD-10-PCS index main term EMG (electromyogram) see Measurement,
Musculoskeletal 4A0F. (ICD-10-PCS index main term Measurement and sub-
