Summary & Overview
CPT 0722T: Quantitative CT Tissue Characterization and Interpretation
CPT code 0722T is an add-on imaging code for quantitative CT tissue characterization in which a provider applies imaging data and software to derive tissue metrics and issues a formal interpretation and report. As an adjunct to a concurrently acquired diagnostic CT exam of at least one anatomic structure, this code captures advanced post-processing and quantitative analysis rather than image acquisition alone. Nationally, the code matters because it reflects payer recognition of advanced image quantification workflows and separates analytic interpretation services from standard CT reporting.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical scope, typical sites of service, and where it fits in imaging service lines. The publication also summarizes expected benchmarks and policy considerations such as payer coverage patterns, coding and billing practice implications for additive post-processing services, and clinical context on when quantitative CT tissue characterization is reported. Data not available in the input is noted where specific coverage rules, reimbursement rates, or associated ICD-10 diagnoses would otherwise be listed.
Billing Code Overview
CPT code 0722T describes an add-on imaging interpretation and report service in which a provider uses imaging data and specialized software for quantitative CT tissue characterization. The service involves deriving quantitative tissue metrics from CT imaging datasets and producing a formal interpretation and report based on that analysis.
Service type: Quantitative CT tissue characterization and interpretation
Typical site of service: Outpatient or inpatient diagnostic imaging settings where CT studies are performed, including hospital radiology departments, outpatient imaging centers, and other sites that perform diagnostic CT exams. The code is appropriate when the quantitative analysis is performed in conjunction with a concurrently acquired CT exam of at least one anatomic structure included in the diagnostic imaging dataset.
Clinical & Coding Specifications
Clinical Context
A 68-year-old male with a history of chronic obstructive pulmonary disease and coronary artery disease undergoes a chest CT for evaluation of progressive dyspnea and concern for emphysema progression. During a diagnostic CT acquisition of the thorax, the facility processes the same imaging dataset with advanced quantitative software to perform CT tissue characterization of lung parenchyma and/or cardiac structures. The interpreting physician reviews the quantitative outputs, integrates them with the diagnostic CT images, and generates a focused interpretation and separate report describing volumetric measures, tissue density metrics, and regional mapping relevant to emphysema severity and/or myocardial tissue characterization. The service is reported as an add-on quantitative CT tissue characterization service when billed in conjunction with the primary diagnostic CT of at least one anatomic structure captured in the same acquisition. Typical workflow steps include image acquisition in the radiology suite, transfer of DICOM images to specialized post-processing software, algorithmic tissue analysis, physician review and correlation with diagnostic images, and issuance of the interpretation report to the referring clinician. Typical site of service is an outpatient or hospital-based radiology department or ambulatory imaging center. Typical patient scenarios include evaluation of diffuse lung disease (emphysema, interstitial lung disease), quantitative assessment of myocardial tissue on cardiac CT, or other tissue characterization tasks performed concurrently with a diagnostic CT study of the involved anatomy.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the quantitative analysis and report require substantially greater work or documentation than typical for the add-on service. |
26 | Professional component | Use when reporting only the physician interpretation/report portion separate from technical image acquisition or processing. |
52 | Reduced services | Use when the post-processing or interpretation is partially reduced or truncated compared with the usual service. |
53 | Discontinued procedure | Use when the planned quantitative analysis/interpretation is started but terminated due to patient or technical issues. |
76 | Repeat procedure by same physician | Use when the quantitative CT tissue characterization is repeated later the same day by the same provider. |
77 | Repeat procedure by another physician | Use when a second provider repeats the quantitative analysis or interpretation the same day. |
80 | Assistant surgeon | Rarely used; apply only if an assistant with appropriate credentialing contributed to the procedure workflow under payer rules. |
82 | Assistant surgeon (when qualified resident not available) | Use similarly to 80 when an assistant is necessary and usual resident coverage is absent. |
TC | Technical component | Use when billing only the technical component (image acquisition and post-processing) without the professional interpretation. |
26 | Professional component | (See above) Use when billing only the physician interpretation/report. |
