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

Circulatory

Circulatory measurement here refers to assessment of the blood circulation as a whole system rather than a single named vessel, using a novel device or technique to quantify a parameter such as overall perfusion, cardiac output, or a composite hemodynamic index. This broader qualifier applies when the technology samples or monitors the circulatory system generally, for example evaluating systemic blood flow adequacy or oxygen delivery during a critical illness or perioperative period, rather than isolating a specific artery or vein. Because the value is intentionally non-specific to one structure, the medical record should clearly state what circulatory parameter was measured and the mechanism of the device, since that information is what justifies coding to the circulatory qualifier instead of a more anatomically discrete measurement value.

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: Infection, Phenotypic Fully Automated Rapid Susceptibility Technology with Controlled Inoculum

This value designates a fully automated diagnostic system that determines antibiotic susceptibility of an infecting organism using a phenotypic method with a controlled, standardized inoculum, yielding results faster than traditional culture-based susceptibility testing. It supports earlier, targeted antimicrobial therapy. It differs from genotypic or molecular infection tests, which detect genetic material rather than observing organism growth response to antibiotics.

Qualifier: New Technology Group 10

New Technology Group 10 flags a procedure as part of the 2023 batch of add-on codes recognized under the New Technology section. The value itself carries no information about the device or drug involved; that comes from the table, body part, and approach values alongside it. Coders should not confuse it with Group 9 or Group 11, which cover the cohorts approved in the years immediately before and after.

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.
