About the XX2 Code Range
The ICD-10-PCS root operation Monitoring (code XX2) in the New Technology section refers to the use of advanced methods to observe physiological systems without invasive intervention.
This operation captures innovative monitoring techniques designed to assess various body functions accurately. Examples include computer-aided monitoring of brain electrical activity (code XX20X89), which helps in detecting neurological conditions, and the adhesive ultrasound patch technology used for tracking blood flow (code XX25X0A). Additionally, the system supports monitoring of muscle compartment pressure with micro-electro-mechanical systems via a percutaneous approach (code XX2F3W9), and noninvasive monitoring of interstitial fluid volume through electrical biocapacitance at an external approach (code XX2KXP9). These codes ensure precise documentation of novel physiological monitoring technologies within the ICD-10-PCS framework.
Questions About This Page
How many billable codes are in the XX2 range?
Of the 6 codes in this range, 5 are billable and valid for inpatient claim submission from October 1, 2025 through September 30, 2026. Table header codes group them but cannot be reported on claims.
What does the XX2 range classify?
The range classifies Monitoring procedures, determining the level of a physiological or physical function repetitively over a periodof time, performed on the physiological systems. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
