CPT 76981: Ultrasound Elastography for Organ Baseline Assessment

CPT code 76981 represents ultrasound elastography performed to assess an organ’s functional tissue by measuring its return to shape after distortion with high‑intensity ultrasound. As a diagnostic imaging modality, elastography provides noninvasive quantification of tissue stiffness that can support evaluation of conditions such as chronic liver disease and other organ‑specific disorders. Nationally, the code is important as imaging technology and clinical guidelines evolve, affecting utilization, coding guidance, and payer coverage policies.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of reimbursement and coverage considerations across major national payers, clinical context for when ultrasound elastography is typically used, and benchmarking content where available. The publication explains typical service settings and the clinical rationale for baseline elastography measurements, and it highlights common billing modifiers and coding considerations that appear with this procedure. Data not available in the input is noted where applicable.

Billing Code Overview

CPT code 76981 describes ultrasound elastography of an organ, a diagnostic ultrasound procedure that measures tissue elasticity by assessing how the organ returns to its normal shape after being distorted by high‑intensity ultrasound waves. The procedure is used to establish a baseline assessment of an organ’s functional (nonconnective, nonstructural) tissue characteristics.

Service type: Diagnostic ultrasound elastography
Typical site of service: Imaging suite or radiology department (commonly performed in outpatient imaging centers, hospital radiology departments, or specialized liver clinics)

Clinical & Coding Specifications

Clinical Context

A 56-year-old patient with chronic hepatitis C is referred to hepatology for noninvasive assessment of liver fibrosis. The clinician orders ultrasound elastography to quantify liver stiffness as a baseline and to monitor progression of hepatic fibrosis. On arrival, the patient is registered, consent is confirmed, and relevant history (alcohol use, prior imaging, labs including liver function tests and platelet count) is reviewed. The procedure is performed in an outpatient radiology or gastroenterology clinic equipped with ultrasound elastography-capable equipment. The provider places the patient supine with the right arm overhead, identifies the right hepatic lobe using grayscale ultrasound, and performs multiple elastography measurements avoiding large vessels and bile ducts. Results documenting median liver stiffness in kilopascals and quality metrics are entered into the radiology report. Images and stiffness measurements are saved to the PACS and communicated to the referring hepatologist for care planning and follow-up surveillance.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when billing only the physician’s interpretation and report separate from the technical component.
`TC`	Technical component	Use when billing only the equipment, staff, and facility portion of the service.
`59`	Distinct procedural service	Use when elastography is separately identifiable from other ultrasound procedures performed the same day and not bundled.
`76`	Repeat procedure by same physician	Use when the same provider repeats the elastography on the same day for technical reasons.
`77`	Repeat procedure by another physician	Use when a different provider repeats the elastography on the same day.
`52`	Reduced services	Use when the procedure is partially reduced or not completed for clinical/technical reasons.
`53`	Discontinued procedure	Use when the procedure is started but discontinued due to patient condition or other issues.
`25`	Significant, separately identifiable evaluation and management service	Use when a separate E/M visit is furnished on the same day as the elastography and is significant beyond routine pre- and post-procedure work.
`59`	Distinct procedural service	Use when elastography is separate from another ultrasound procedure performed the same patient visit (listed again for emphasis if needed).
`59`	Distinct procedural service	Use when billing requires identification of a distinct and separate procedure (avoid duplication if not applicable).
