Summary & Overview
CPT 10008: Fine Needle Aspiration, Additional Lesion under Fluoroscopy
CPT code 10008 represents a fine needle aspiration (FNA) performed to obtain a diagnostic specimen from additional lesions biopsied under fluoroscopic guidance, billed in addition to the primary lesion code 10007. Nationally, accurate use of this code matters for clinical documentation, claims accuracy, and aggregated utilization measures for image-guided diagnostic biopsies. Proper coding distinguishes primary and additional lesion sampling and supports appropriate encounter-level claims adjudication.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find concise benchmarks and guidance on common payer coverage patterns, clinical context for FNA procedures performed under fluoroscopy, and how reporting of additional lesions affects service-level billing. The publication outlines typical sites of service, the clinical intent of FNA for diagnostic sampling of masses or cysts, and the interaction between the primary code 10007 and secondary reporting with 10008.
The summary provides clinicians, coding professionals, and revenue cycle stakeholders with a clear view of the code’s purpose, common use cases, and where to expect attention during claims review. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 10008 describes a fine needle aspiration (FNA) procedure performed to obtain a diagnostic specimen from tissue, a cyst, or a mass. This code is reported for each additional lesion biopsied under fluoroscopic guidance in addition to the primary procedure reported with CPT code 10007.
Service Type: Image-guided diagnostic biopsy (fine needle aspiration)
Typical Site of Service: Hospital outpatient department, ambulatory surgery center, or radiology suite

Clinical & Coding Specifications
Clinical Context
A 58-year-old patient presents with a persistent, palpable thyroid nodule and ultrasound findings concerning for a solid, suspicious lesion. The interventional radiologist schedules a fluoroscopically guided fine needle aspiration (FNA) during the same visit to obtain cytologic material for diagnosis. The patient is positioned in the procedure suite, targeted lesion localization is performed using fluoroscopy, the skin is prepped and anesthetized, and a fine-gauge needle with syringe is advanced into the lesion under image guidance. Multiple passes are performed as needed. If more than one distinct lesion is biopsied under fluoroscopic guidance during the same session, the initial lesion is reported with the primary FNA- fluoroscopy code and each additional lesion is reported with 10008. The typical site of service is an outpatient ambulatory procedure suite, radiology or interventional radiology department, or hospital outpatient setting. Common clinical workflow includes pre-procedure consent, coagulation check, local anesthesia, image-guided needle aspiration, specimen labeling and submission to cytology, post-procedure monitoring, and documentation of lesions sampled and number of passes per lesion.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
11 | Preservice and postservice bundled | Use when this service represents the usual, expected level of service by the reporting clinician and is the standard performance of the procedure. |
22 | Increased procedural services | Use when the work required is substantially greater than typical (e.g., unusually difficult lesion access, markedly increased number of passes). |
23 | Unusual anesthesia | Use when general anesthesia or deep sedation is required for this FNA due to patient condition. |
52 | Reduced services | Use when the procedure is partially reduced or not completed as originally planned. |
53 | Discontinued procedure | Use when the procedure is started but terminated due to extenuating circumstances or a complication. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons due to case complexity. |
73 | Discontinued outpatient hospital/ASC prior to anesthesia | Use when the outpatient procedure is started but discontinued prior to administration of anesthesia. |
78 | Unplanned return to operating/procedure room by the same physician following initial procedure for a related procedure during the postoperative period | Use for return to the procedure room for a complication related to the initial FNA during the global period. |
80 | Assistant at surgery | Use when an assistant surgeon provides active assistance during the procedure. |
81 | Minimum assistant surgeon | Use when a minimum assistant surgeon is required and documented. |
82 | Assistant not available; qualified resident surgeon acts as assistant | Use when a resident performs the assistant role in absence of an available qualified assistant. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services furnished in part-time (less than full-time) setting | Use when an advanced practice clinician furnishes a portion of the service per payer rules. |
QK | Medical direction of two, three, or four qualified individuals | Use only when the reporting physician provides required medical direction for qualified assistive personnel per Medicare rules. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
208000000X | Diagnostic Radiology | Most fluoroscopic-guided FNAs are performed by interventional or diagnostic radiologists. |
207P00000X | Otolaryngology (ENT) | ENT surgeons frequently perform FNAs of head and neck masses under image guidance. |
2084P0800X | Interventional Radiology | Interventional radiologists perform percutaneous image-guided FNAs in many anatomic locations. |
207L00000X | General Surgery | General surgeons may perform FNAs of superficial masses in the outpatient setting. |
363A00000X | Pathology (Cytopathology) | Pathologists or cytopathologists are involved in specimen interpretation and rapid onsite evaluation when available. |

C73 | Malignant neoplasm of thyroid gland | Thyroid nodules suspicious for malignancy are commonly evaluated with FNA. |
E04.1 | Nontoxic single thyroid nodule | Benign-appearing solitary nodules are sampled to exclude malignancy. |
R22.1 | Localized swelling, mass and lump, neck | Palpable neck masses are an indication for image-guided FNA to establish diagnosis. |
D34 | Benign neoplasm of thyroid gland | Benign thyroid lesions often undergo FNA for cytologic characterization. |
N63 | Unspecified lump in breast | Breast lumps may be aspirated by FNA when cytologic assessment is appropriate. |
R19.0 | Intra-abdominal and pelvic swelling, mass and lump | Deep abdominal masses may be targeted under fluoroscopic guidance for FNA. |
K63.5 | Polyp of colon | When percutaneous sampling of accessible lesions is indicated in select cases, FNA may be used. |

Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|---|---|
10007 | Fine needle aspiration; with imaging guidance (e.g., ultrasound), first lesion | Primary imaging-guided FNA code; 10008 is reported for each additional lesion biopsied under fluoroscopic guidance in addition to 10007. |
76942 | Ultrasonic guidance for needle placement (eg, biopsy, aspiration, injection, localization device), imaging supervision and interpretation | Often used when ultrasound, rather than fluoroscopy, is used for needle localization during FNA; documents imaging guidance performed. |
77002 | Fluoroscopic guidance for needle placement (e.g., biopsy, aspiration, injection, localization), imaging supervision and interpretation | Used to report fluoroscopic imaging guidance associated with percutaneous needle placement; supports documentation when fluoroscopy is the modality used. |
88172 | Cytopathology, immediate cytologic evaluation; gross and microscopic examination during fine needle aspiration (e.g., ROSE) | Reported when a cytopathologist or qualified practitioner performs immediate onsite evaluation of FNA specimens to assess specimen adequacy. |
19000 | Biopsy of breast; needle core, not vacuum assisted, single or multiple (Note: included as commonly associated when multiple sampling methods are used) | Performed when core needle biopsy is used instead of or in addition to FNA for breast masses; may be part of the same diagnostic pathway. |
