Under the National Correct Coding Initiative (NCCI), which sets Centers for Medicare & Medicaid Services (CMS) payment policy as well as that of many private payers, one unit of service is allowed for CPT code 76942 in a single patient encounter regardless of the number of needle placements performed. Per NCCI, “The unit of service for these codes is the patient encounter, not number of lesions, number of aspirations, number of biopsies, number of injections, or number of localizations.”
Per the Radiology section of the NCCI, “Ultrasound guidance and diagnostic ultrasound (echography) procedures may be reported separately only if each service is distinct and separate. If a diagnostic ultrasound study identifies a previously unknown abnormality that requires a therapeutic procedure with ultrasound guidance at the same patient encounter, both the diagnostic ultrasound and ultrasound guidance procedure codes may be reported separately. However, a previously unknown abnormality identified during ultrasound guidance for a procedure should not be reported separately as a diagnostic ultrasound procedure.”
Under the Medicare program, the International Classification of Diseases 10th Revision (ICD-10) code selected should be based on the test results, with 2 exceptions. If the test does not yield a diagnosis or was normal, the physician should use the pre-service signs, symptoms, and conditions that prompted the study. If the test is a screening examination ordered in the absence of any signs or symptoms of illness or injury, the physician should select “screening” as the primary reason for the service and record the test results, if any, as additional diagnoses.
Modifiers must be used in specific settings. In the office, physicians who own the equipment and perform the service themselves (or the service is performed by an employed or contracted sonographer) may bill the global fee without any modifiers. However, if billing for a procedure on the same day as an office visit, the -25 modifier must be used. This indicates “[a] significant, separately identifiable evaluation and management service.” This modifier should not be used routinely. If the service is performed in a hospital, the -26 modifier must be used to indicate that the professional service only was provided when the physician does not own the machine (Tables 2, 3, 4). The payers will not reimburse physicians for the technical component in the hospital setting.
Reimbursement
In general, medical insurance plans will cover ultrasound studies when they are medically indicated. However, we recommend checking with each individual private payer directly, including Medicare. Medicare Part B will generally reimburse physicians for medically necessary diagnostic ultrasound services, provided the services are within the scope of the physician’s license. Some Medicare contractors require that the physician who performs and/or interprets some types of ultrasound examinations be capable of demonstrating relevant, documented training through recent residency training or post-graduate continuing medical education (CME) and experience. Medicare does not differentiate by medical specialty with respect to billing medically necessary diagnostic ultrasound services, provided the services are within the scope of the physician’s license. Some Medicare contractors have coverage policies regarding either the diagnostic study or ultrasound guidance of certain injections, or both.
Payment policies for beneficiaries enrolled in Medicare Part C, known as the Medicare Advantage plans, will reflect those of the private insurance administrator. The Medicare Advantage plan may be either a health maintenance organization (HMO) or a preferred provider organization (PPO). Private insurance payment rules vary by payer and plan with respect to which specialties may perform and receive reimbursement for ultrasound services. Some payers will reimburse providers of any specialty for ultrasound services, while others may restrict imaging procedures to specific specialties or providers possessing specific certifications or accreditations. Some insurers require physicians to submit applications requesting ultrasound be added to their list of services performed in their practice. Physicians should contact private payers before submitting claims to determine their requirements and request that they add ultrasound to the list of services.
When contacting the private payers, ask the following questions:
- What do I need to do to have ultrasound added to my practice’s contract or list of services?
- Are there any specific training requirements that I must meet or credentials that I must obtain in order to be privileged to perform ultrasound in my office?
- Do I need to send a letter or can I submit the request verbally?
- Is there an application that must be completed?
- If there is a privileging program, how long will it take after submission of the application before we are accepted?
- What is the fee schedule associated with these codes?
- Are there any bundling edits in place covering any of the services I am considering performing? (Be prepared to provide the codes for any non-ultrasound services you will be performing in conjunction with the ultrasound services.)
- Are there any preauthorization requirements for specific ultrasound studies?
- Are there any preauthorization requirements for specific ultrasound studies?
