Operation Definition
Determining the level of a physiological or physical function at a point in time
Procedure Overview
Measurement procedures in this family determine the level of a physiological or physical function at one specific moment, rather than tracking it over time. A clinician orders this kind of test to get a snapshot reading - for example, a pressure, flow, or biochemical value - that informs an immediate treatment decision, such as whether a patient needs a particular intervention or how a disease is progressing.
Because these fall under New Technology, the measurement typically relies on a device, imaging technique, or diagnostic platform recently approved and not yet incorporated into the standard PCS measurement tables. Patients might encounter this during diagnostic workup for cardiovascular, neurological, or other conditions where a precise, single-point reading changes what happens next in their care.
Anatomy & Axis Detail
Cardiac
Measurement of cardiac function using New Technology captures a single determination of a heart-related physiologic parameter obtained with an emerging device or technique, distinguishing it from ongoing cardiac monitoring by its discrete, one-time nature. Such measurements might assess a novel biomarker of cardiac performance, a specialized hemodynamic value, or another parameter not reliably obtainable with established diagnostic tools, and are often used to guide a specific treatment decision, such as whether to proceed with an intervention. Because the heart's function fluctuates with loading conditions and rhythm, the timing and context of a single measurement matter for interpreting the result accurately. Documentation should name the specific New Technology device or method used and confirm that only one measurement was obtained, rather than the sustained tracking that would instead be coded under Monitoring.
Approach: External
External approach in New Technology applies to procedures performed directly on the skin, mucous membranes, or via direct visualization without penetrating a body cavity, such as applying or activating a device against the body surface. It contrasts with Percutaneous approaches, which require instrument entry through the skin rather than surface-level contact.
Device / Substance / Technology: Output, Computer-aided Assessment
This qualifier refers to a computer-aided assessment device applied to a physiologic output measurement, most commonly cardiac output, using algorithmic analysis of monitored data to support clinical decision-making. It provides an automated, continuous evaluation rather than a single point-in-time reading. It should be distinguished from flow-specific assessment devices, such as those for coronary or pulmonary artery flow, which target a particular vascular bed.
Qualifier: New Technology Group 9
Group 9 is the seventh-position qualifier used in the New Technology section to mark a device, substance, or technique as belonging to the 2022 annual cohort of new technology add-on codes. It has no clinical meaning of its own beyond that vintage tag, so coders rely on the specific table and body system to know what procedure it applies to. It is distinguished from Group 8 and Group 10 purely by the fiscal year the technology was approved for separate identification.
Coding & Documentation
A code from this family is appropriate when the medical record documents a discrete, one-time measurement using the specific new technology named in the code's device or product qualifier, along with the physiological parameter being measured. The report should state the value obtained and the clinical purpose, since payers and auditors expect to see that the measurement directly informed care.
The most common error is confusing a single diagnostic measurement with a monitoring episode and assigning the wrong root operation, or overlooking that the specific technology used doesn't match any approved New Technology code, in which case a standard Section 4 Measurement code is more appropriate. Coders should also confirm the measurement wasn't performed as part of a broader monitoring protocol already captured elsewhere.
Commonly Confused With
The closest source of confusion is the Monitoring family within the same body system, since both determine a physiological value using new technology. The dividing line is timing: Measurement is a single point-in-time value, while Monitoring is repeated or continuous. It can also be confused with standard PCS Measurement codes outside New Technology when the device or method used isn't actually one of the specifically approved new technologies.
