77014

Computed tomography guidance for needle placement (e.g., biopsy, aspiration, injection, localization device), radiological supervision and interpretation

CPT code 77014 describes the radiological supervision and interpretation (S&I) for computed tomography (CT) guidance utilized during needle placement procedures. This service encompasses the radiologist's expert role in planning the procedure, performing real-time image guidance, ensuring accurate placement of a needle or other device within a target lesion or anatomical structure, and interpreting the CT images acquired during the guidance phase. It is used for a variety of diagnostic and therapeutic interventions, including biopsies of suspicious masses, aspiration of fluid collections (e.g., abscesses, cysts), delivery of therapeutic agents (e.g., nerve blocks, tumor ablation), or the precise placement of localization devices or fiducial markers. This code specifically covers the imaging guidance component and is reported in addition to the code for the primary procedure performed via the needle.

Clinical Indications

  • Diagnosis of suspicious lesions (e.g., lung nodules, liver masses, retroperitoneal masses, bone lesions) requiring image-guided biopsy to obtain tissue for pathological examination.
  • Aspiration or drainage of deep-seated fluid collections (e.g., abscesses, seromas, hematomas, cysts) for diagnostic analysis or therapeutic relief.
  • Targeted delivery of therapeutic agents for pain management (e.g., nerve blocks, facet joint injections, radiofrequency ablation) or for tumor treatment (e.g., chemotherapy, ablation).
  • Preoperative localization of non-palpable lesions for surgical excision.
  • Placement of fiducial markers for radiation therapy planning or stereotactic radiosurgery.

Procedure Steps

  1. Pre-procedure planning, including review of prior imaging, patient history, and obtaining informed consent. Determination of optimal patient positioning, needle trajectory, and target lesion/area.
  2. Acquisition of initial scout and localization CT images to precisely identify the target and plan the entry site and path.
  3. Patient positioning, sterile skin preparation, and administration of local anesthesia at the planned needle entry site.
  4. Introduction of the needle through the skin and advancement towards the target, with intermittent CT image acquisition to monitor trajectory and depth in real-time.
  5. Confirmation of accurate needle tip position within the desired target using additional CT images.
  6. Performance of the primary procedure (e.g., biopsy tissue collection, fluid aspiration, therapeutic agent injection) once accurate needle position is confirmed.
  7. Acquisition of post-procedure CT images (if necessary) to assess for immediate complications (e.g., hemorrhage, pneumothorax) or to document the final position of any placed device.
  8. Comprehensive documentation of the procedure, findings, and any complications encountered.

Coding Guidelines

  • CPT code 77014 is used to report the radiological supervision and interpretation (S&I) of CT guidance for needle placement and is always reported in conjunction with a primary procedure code that describes the definitive needle placement service (e.g., biopsy, aspiration, injection). It cannot be billed as a standalone service.
  • This code represents guidance for a single session regardless of the number of passes or biopsies taken from a single target during that session. For multiple distinct lesions or anatomical sites requiring separate CT guidance sessions, 77014 may be reported multiple times with appropriate modifiers (e.g., 59, XU) if clinically justified and documented.
  • Modifier 26 should be appended if only the professional component (radiologist's work) is being billed, or the TC modifier for the technical component.
  • Do not report 77014 in conjunction with other imaging guidance codes (e.g., ultrasound (76942), fluoroscopy (77002), magnetic resonance (77021)) for the same needle placement procedure, as only one form of guidance should be chosen based on the primary imaging modality used.
  • Documentation must clearly specify the medical necessity for CT guidance, the target lesion/site, the procedure performed, and the supervision and interpretation by the radiologist.
