Compliance Question of the Week – Radiology

If a screening Mammogram (77067) and tomosynthesis (77063) are performed unilaterally, should Modifier 52 be placed on both CPTs®?

For proper reporting of CTA exams, there is a well-documented list of acceptable 3D techniques to satisfy the code requirement. These are 3D MIP, surface-shaded rendering, and volume rendering, as well as “other 3D techniques.” We’ve come across dictations that state 2D MIPs. Is this a type of 3D technique?

In regard to last week’s question, should a study be initiated but not completed, what modifier would we report with the code?

Can we charge for 78999-“Unlisted miscellaneous procedure, diagnostic nuclear medicine” to reflect the administration of the radiopharmaceutical given for diagnostic purposes?

Can you provide any insight or coding tips for codes 76014 and 76015? Specifically, can we charge 76014 for every patient with an implanted device if we must review prior documentation to determine whether the device is MRI-compatible?

If a patient is scheduled for a CT with and without contrast, but the patient refuses the contrast, should we bill the code for the CT without contrast, or should we bill for the exam with/without a modifier? What modifier would be appropriate to use in this scenario?

Can you tell us how many times the new 2026 add-on codes for lithotripsy can be reported per iliac territory and femoral/popliteal territory?

As a follow-up to last week’s question, if injections are performed unilaterally at multiple levels, how would we code?

How should we report a facet joint injection performed on the left side at one level and on the right side at a different level within the same spinal region? What about bilateral cases?

How would you code when a radiologist is asked to create a new access, or enlarge an existing access, for a urologist to perform subsequent endourologic procedures?

What is the difference between a ‘catheter’ and a ‘stent’ in genitourinary procedures?

Is there a code for removal of a gastrostomy or other colonic tube?
