Clinical Context
A 54-year-old male presents to the outpatient imaging center with persistent right upper quadrant abdominal pain and elevated liver function tests. The clinician orders a focused abdominal ultrasound to evaluate the gallbladder for cholelithiasis and the biliary tree for obstruction. The patient is registered for a limited, real-time abdominal ultrasound of the right upper quadrant, performed by a diagnostic medical sonographer with real-time interpretation by a radiologist. Images and cine loops of the liver, gallbladder, common bile duct, and surrounding quadrant are documented and archived. The report includes focused measurements, description of any stones, ductal dilation, and a focused impression. If findings require further evaluation, a complete abdominal ultrasound or targeted follow-up study may be scheduled. Typical sites of service include outpatient imaging centers, hospital radiology departments, and emergency departments when a rapid, limited assessment is needed.
Coding Specifications
| Modifier | Description | When to Use |
|---|
26 | Professional component | Use when billing only the physician interpretation/report for the ultrasound separate from technical acquisition. |
|TC|Technical component|Use when billing only the technical component (sonographer and equipment) separate from physician interpretation.
|52|Reduced services|Use when the ultrasound is partially reduced or incomplete due to patient factors or technical limitations.
|53|Discontinued procedure|Use when the exam is started but terminated due to patient instability or other immediate medical reasons.
|76|Repeat procedure by same physician|Use when the same provider performs a repeat limited abdominal ultrasound on the same day.
|77|Repeat procedure by another physician|Use when a different provider repeats the limited ultrasound on the same day.
|59|Distinct procedural service|Use when the limited ultrasound is distinct from another procedure performed at the same encounter and needs to be identified as separate.
|25|Significant, separately identifiable E/M service|Use when a separate evaluation and management service is performed on the same day as the ultrasound and requires billing in addition to the imaging.
|52|Reduced services|(Listed above) applicable when scope is less than typical limited exam; include when documentation supports reduction.
|91|Repeat clinical diagnostic laboratory test|Although used primarily for lab tests, some payors accept 91 when same-day repeat of diagnostic tests is required due to technical failure; use only per payor policy.
| Taxonomy Code | Specialty | Notes |
|---|
207RC0000X | Radiology - Diagnostic Radiology | Radiologists commonly interpret and report abdominal ultrasound examinations. |
|222100000X|Diagnostic Medical Sonographer|Sonographers perform the real-time image acquisition under direction of a physician.
|207L00000X|Emergency Medicine|Emergency physicians often order and sometimes perform limited abdominal ultrasounds in the ED setting.
|207K00000X|Gastroenterology|Gastroenterologists may request or perform targeted abdominal ultrasound for hepatobiliary follow-up and intervention planning.
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|
K80.20 | Calculus of gallbladder without cholecystitis, without obstruction | Common indication for a right upper quadrant limited ultrasound to detect gallstones. |
|K83.1|Obstruction of bile duct|Indication for limited ultrasound to assess common bile duct dilation and possible obstructing stone.
|R10.11|Right upper quadrant pain|Frequent presenting symptom prompting a focused abdominal ultrasound of the RUQ.
|R17|Unspecified jaundice|Ultrasound is used to evaluate hepatobiliary causes of jaundice, including obstruction and cholestasis.

|I71.3|Abdominal aortic aneurysm, ruptured|A limited abdominal ultrasound may be used emergently to assess for abdominal aortic aneurysm; follow-up vascular imaging is often required.
|R18.8|Other ascites|Ultrasound detects and quantifies intra-abdominal fluid and can guide paracentesis.
|K75.9|Inflammatory liver disease, unspecified|Used when inflammatory hepatic processes are suspected and a focused liver ultrasound is indicated.
Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|
76700 | Complete abdominal ultrasound; limited or complete, real time including image documentation of the abdomen and retroperitoneal organs | Performs a comprehensive exam of multiple abdominal organs when a limited study (76705) is insufficient or when pathology extends beyond a single organ/quadrant. |
|76770|Transabdominal ultrasound, limited or complete, pregnant uterus|Used in obstetric settings; not for abdominal organ evaluation but may be relevant when pregnancy is in differential or concurrent.
|76942|Ultrasound guidance for needle placement (e.g., paracentesis) including imaging documentation|May be used when a limited abdominal ultrasound identifies free fluid requiring diagnostic or therapeutic paracentesis under ultrasound guidance.
|99213|Office or other outpatient visit for the evaluation and management of an established patient, moderate complexity|Represents a common E/M service that may be billed the same day as 76705 when a significant, separately identifiable office visit is performed (use modifier 25 if appropriate).
|93975|Duplex scan of abdominal arteries; limited or follow-up study|May be ordered when a limited abdominal ultrasound identifies aortic or major arterial concerns requiring vascular-specific duplex evaluation.
