What 77012 covers

This service covers CT imaging used to plan and guide a needle to a target, with images used to check the needle’s position during placement. Radiologists and interventional radiologists commonly perform it in hospital imaging departments, outpatient radiology centers, or other settings equipped for CT-guided procedures. Typical cases include directing a biopsy needle into a lung, liver, kidney, bone, or soft-tissue lesion. The biopsy, aspiration, or other needle procedure is distinct from the imaging guidance service.

Report 77012 when CT provides the guidance for needle placement, rather than fluoroscopy or MRI. Documentation should support the target, the use of CT to guide placement, and the imaging supervision and interpretation. CMS recognizes professional and technical components: modifier 26 identifies interpretation, modifier TC identifies the equipment and staff portion, and reporting the code without either modifier represents the global service. The separately priced components may be billed by different entities when each performs its portion.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

77012 billing questions

Does 77012 include the biopsy or aspiration?

No. It represents the CT guidance for needle placement; the biopsy, aspiration, or other intervention is a separate service when separately reportable.

When should 77012 be chosen instead of 77002?

Use 77012 when CT guides the needle. Code 77002 is for fluoroscopic needle guidance.

How are modifiers 26 and TC used?

Modifier 26 identifies the professional interpretation component, and modifier TC identifies the technical component. Without either modifier, the claim represents the global service.

What documentation supports reporting 77012?

Document the target and procedure, use of CT to guide needle placement, and the imaging supervision and interpretation. The record should support the component billed.

Is 77012 used for CT-guided tissue ablation?

Use 77013 for CT guidance of tissue ablation. Use 77012 when CT is guiding needle placement for a different intervention, such as a biopsy.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
