CPT code 76700, 76705, 76770, 76775 -Ultrasound procedure frequency limitation

Ultrasound Frequency Limitations

Reimbursement for the following Procedure-4 radiological ultrasound procedure codes is limited to four claims per year, for the same recipient, by any provider.  Additional claims for these codes must be accompanied with appropriate medical justification or the claim will be denied.


Procedure-4 Code    Description

76604    Ultrasound, chest (includes mediastinum), real time with image documentation

76700    Ultrasound, abdominal, real time with image documentation; complete

76705    limited (eg, single organ, quadrant, follow-up)

76770    Ultrasound, retroperitoneal (eg, renal, aorta, nodes), real time with image documentation; complete

76775    limited

Billing and Coding Guidelines


Abdominal ultrasound examinations (Procedure codes 76700- 76775) and abdominal duplex examinations (Procedure codes 93975, 93976) are generally performed for different clinical scenarios although there are some instances where both types of procedures are medically reasonable and necessary. In the latter case, the abdominal ultrasound procedure Procedure code should be reported with an NCCI-associated modifier.


Procedure Code           Bundled with            Rule       Formula Used to Determine Bundled Amount

76700   When any combination of column A codes are billed

 100% of the highest RVU, 50% of the second and 25% of the third or lesser RVU's



Procedure Codes 76700 & 76705 and ICD.10 code Z87.891 added to guideline. Replaced ICD.9 codes with ICD.10 codes in Examples of Claim Adjudication Scenarios section



Abdomen and Retroperitoneum Ultrasounds

Is a particular imaging study a limited or complete procedure? There are four ultrasound codes that can be challenging. Choosing an incorrect code could have an impact on reimbursement. The four codes are:

* 76700 - Ultrasound, abdominal, real time with image documentation; complete

* 76705 - ..........limited (eg, single organ, quadrant, follow-up)

* 76770 - Ultrasound, retroperitoneal (eg, renal, aorta, nodes), real time with image documentation; complete

* 76775 - ..........limited

Per Procedure, “A complete ultrasound examination of the abdomen (76700) consists of real time scans of the liver, gallbladder, common bile duct, pancreas, spleen, kidneys, and the upper abdominal aorta and inferior vena cava including any demonstrated
abdominal abnormality.”

Per Procedure, “A complete ultrasound examination of the retroperitoneum (76770) consists of real time scans of the kidneys, abdominal aorta, common iliac artery origins, and inferior vena cava, including any demonstrated retroperitoneal abnormality.” Alternatively, if clinical history suggests urinary tract pathology, complete evaluation of the kidneys and urinary bladder also comprises a complete retroperitoneal ultrasound.

• Trauma Ultrasound:

Currently, there are three Procedure codes which reflect separately identifiable elements of the FAST exam as described by the AIUM/ ACEP documents: 1) cardiac 93308-26, 2) abdomen 76705-26, and 3) chest 76604-26.


OB and Abdominal US

* Decision to order and perform an abdominal US is based on indications independent of the state of the patient's pregnancy status, even if the abdominal complication of a pregnancy is suspected (eg, pyelonephritis secondary to ureteral obstruction by a pregnancy or suspected cholecystitis in a pregnant patient with right upper quadrant pain).

* The abdominal ultrasound codes 76700, 76705 should be reported for an ultrasound of the abdomen when signs and symptoms indicate the necessity of an abdominal ultrasound procedure

LIVER ELASTOGRAPHY

X New code 91200 was added for liver elastography performed via mechanically-induced shear wave technique, such as vibration. The code includes interpretation and report, but not imaging. The code describes liver fibrosis evaluation, such as Fibroscan®, Philips® shear wave ultrasound elastography and other hepaticshear wave technologies. If performing ultrasound  with liver elastography, report using 76700, Ultrasound, abdominal, real time imaging documentation, complete, OR 76705, Ultrasound, abdominal, real time with image documentation; limited (e.g., single organ, quadrant, follow up), AND 0346T, Ultrasound, elastography (list separately in addition to code for primary procedure).


Q: If a vascular study (with or without color Doppler) is performed in conjunction with ultrasound of the liver, is it appropriate to report both Procedure code 76705 (Abdominal ultrasound, limited) and Procedure code 93975 (Duplex scan of arterial inflow and venous outflow of abdominal, pelvic and/or retroperitoneal organs; complete study)? 


Yes, if an ultrasound of the liver is performed, and there is a clinical need for further evaluation by duplex scanning, then it is appropriate to code for both 76705 and 93975.

A vascular study (with or without color flow) may be reported in addition to ultrasound studies when it is clinically indicated (medically necessary). The radiology codes for ultrasound (e.g. abdomen, retroperitoneal, etc.) generally represent two-dimensional (gray-scale) imaging. For example, Procedure code 76700 includes gray-scale real-time or static images of the entire abdomen
from the diaphragm to the level of the umbilicus. If the study includes anything less than the allinclusive code 76700, then the limited code 76705 should be billed.


Sometimes a vascular study is added to the basic gray-scale study when enhancement of suspect areas or more detailed analysis is needed. Procedure code 93975 describes evaluation of arterial inflow and venous outflow of abdomen, retroperitoneum, scrotal contents and/or pelvic organs. This code can be used whether single or multiple organs are studied. It is a "complete" procedure in that all major vessels supplying blood flow (inflow and outflow, with or without color flow mapping) to the organ are evaluated. If the study is only a partial evaluation, then the limited code (93976) is billed. Therefore, in cases where it is necessary to perform a vascular study in conjunction with ultrasound of an organ, it would be appropriate to report the vascular study separately.

In order to code an abdominal duplex study, true vascular analysis needs to be performed. Abdominal duplex should not be coded when color is just turned on to determine if a structure is vascular (e.g., distinguishing hepatic artery from the common bile duct). Color Doppler alone, when performed for anatomic structure identification in conjunction with a real-time ultrasound examination, is not reported separately.

4 Note that since January 1997, Medicare Correct Coding Initiative (CCI) edits have been in place for the vascular study codes (93975/93976) when used in conjunction with the pelvic ultrasound codes (76856/76857). Medicare considers these pairs to be mutually exclusive—that is, they should not be performed by the same physician, for the same patient, on the same date of service. The code pair edits do list a modifier indicator of "1" with the vascular study codes (939751 ,939761 );  therefore, it would be appropriate to submit these codes together with a modifier attached to the vascular study code (e.g., 93975–59 or 93976–59). For example, a patient comes in with pelvic pain, and the ultrasound of the pelvis demonstrates an enlarged ovary. The differential diagnosis includes torsion of the ovary. A vascular study is requested to establish the arterial inflow and venous drainage of the ovary and determine torsion or infarction. In this scenario, it would be appropriate to code 76856 for the pelvic ultrasound and 93976-59 for the limited vascular study of the ovary.

Billing of CPT 93306 and 76604 example:

Reimburse for:

93306 – Echocardiography, transthoracic, real-time with image documentation (2D), includes M-mode recording, when performed, complete, with spectral Doppler echocardiography and with color flow Doppler echocardiography.

Deny:

76604 – Ultrasound, chest (includes mediastinum), real time with image documentation.


• For diagnostic ultrasound of the chest, including mediastinum use CPT code 76604. This code is used for the evaluation of the pleural spaces for the presence of fluid and/or masses of the chest, chest wall or mediastinum.
