ICD-10-PCS Table `4A0`
for Physiological Systems, Measurement

The ICD-10-PCS table below specifies all the valid combinations of the remaining characters beyond the first 3 characters (4A0) in the Measurement and Monitoring section, Physiological Systems body system, and Measurement root operation. Each row in the table specifies the valid combination of values for characters 4-7. The table contain only those combinations of values that result in a valid procedure code.
