In simple words: This code is used when a doctor isn't able to do something that a quality measure asks for because of problems with the healthcare system, like not having the right equipment or insurance not covering it.

This modifier is used to indicate that a specific action, as defined in a performance measure, was not carried out due to limitations or issues within the healthcare system. These reasons can include unavailable resources, insurance coverage restrictions, or other constraints related to healthcare delivery.

Example 1: A patient requires a specific diagnostic test outlined in a quality measure, but the facility lacks the necessary equipment. Modifier 3P is appended to the associated quality code., A quality measure recommends a particular therapeutic intervention, but it is not covered by the patient's insurance. The physician uses modifier 3P with the relevant code to indicate the system-related reason for not providing the service., A measure specifies a follow-up consultation within a certain timeframe, but due to a shortage of specialists in the area, the appointment cannot be scheduled within that period. Modifier 3P is used to signify the system-related delay.

The medical record should clearly document the specific system-related reasons for not performing the action detailed in the quality measure. This documentation should be comprehensive and readily accessible for auditing purposes.

** Modifier 3P is part of a set of performance measure exclusion modifiers (1P, 2P, 3P), which allow for reporting when a measure's numerator action is not performed due to specific documented circumstances. It signifies denominator exclusions from the performance measure. It's crucial to understand that accurate reporting, whether the clinical action was performed or not, holds equal importance in a pay-for-reporting model.
