Summary & Overview
CPT 60100: Image-Guided Thyroid Core Needle Biopsy
Headline: CPT code 60100: Image-guided core needle biopsy of the thyroid, a common diagnostic procedure.
Lead: CPT code 60100 represents an image-guided, automatic spring–powered core needle biopsy of the thyroid used to obtain tissue for pathologic diagnosis. The code matters nationally as thyroid nodules are common and accurate tissue diagnosis drives management decisions, impacting both surgical and non-surgical care pathways.
This report covers coverage and payment considerations for major national payers and Medicare. Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, expected sites of service, common coding and billing considerations, and the types of benchmarks and policy updates typically relevant to this service. The summary highlights how payers approach outpatient image-guided procedures and what clinicians and coding teams should expect when documenting indications and imaging guidance.
What readers will learn: an overview of CPT code 60100 clinical purpose and service setting; which national payers are commonly relevant for coverage and payment; typical operational considerations for delivering this outpatient diagnostic procedure; and where to look for payer-specific policy updates and reimbursement benchmarks.

Billing Code Overview
CPT code 60100 describes a diagnostic procedure in which a provider obtains a tissue sample from the thyroid gland using an automatic, spring-powered core needle, typically performed under imaging guidance. This procedure is a core needle biopsy of the thyroid intended to collect a tissue specimen for histopathologic evaluation.
-

Clinical & Coding Specifications
Clinical Context
A 48-year-old woman presents to an outpatient endocrinology clinic with a palpable right thyroid nodule identified on routine exam and confirmed on ultrasound. The nodule measures 1.8 cm with mixed solid and cystic components and microcalcifications. The endocrinologist performs an ultrasound-guided core needle biopsy using an automatic spring-powered core needle to obtain tissue for histopathology and immunohistochemistry. Local anesthesia is given, real-time ultrasound is used for needle guidance, and 2 core samples are obtained. The specimen is sent to pathology with proper labeling and requisition. The patient is monitored in recovery for 30 minutes for bleeding or hematoma before discharge with instructions for wound care and return precautions.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day | Use when a distinct E/M visit is performed and documented on the same day as the biopsy (e.g., new patient history/exam). |
26 | Professional component | Use when billing only the physician professional component of an imaging-guided procedure when the facility bills the technical component separately. |
