CPT Code G0108 is a Medicare-specific HCPCS code used for cervical or vaginal cancer screening and breast cancer screening for eligible patients. This code is specifically designed for high-risk individuals who require more frequent monitoring due to factors such as family history, prior abnormal results, or other medical conditions.
Unlike routine screenings, G0108 is used when a healthcare provider performs a clinical breast exam (CBE) and a pelvic exam (including a Pap smear, if necessary) for patients at elevated risk. Proper use of this code ensures accurate billing and reimbursement while promoting early detection of cancers in vulnerable populations.

2. Understanding the Importance of Pelvic and Breast Cancer Screening
Why Early Detection Matters
-
Breast cancer is the second most common cancer in women, with 1 in 8 women developing it in their lifetime.
-
Cervical cancer, though preventable, still affects thousands annually, with early detection drastically improving survival rates.
-
High-risk patients (those with genetic predispositions, prior cancer history, or HPV infections) benefit from more frequent screenings.
Role of G0108 in Preventive Care
-
Ensures Medicare beneficiaries receive necessary screenings without financial barriers.
-
Encourages consistent follow-ups for patients with abnormal prior results.
-
Helps providers track patient history and recommend further diagnostic tests if needed.
3. Eligibility Criteria for G0108
Not all patients qualify for G0108. Medicare outlines specific eligibility requirements:
Patient Eligibility
| Criteria | Details |
|---|---|
| High-risk for breast cancer | Family history, genetic mutations (BRCA1/2), prior breast cancer |
| High-risk for cervical cancer | HPV-positive, prior abnormal Pap smears, DES exposure |
| Age requirements | Medicare beneficiaries (typically women aged 35+ with risk factors) |
Provider Eligibility
-
Must be a qualified healthcare professional (physician, nurse practitioner, or PA).
-
Must document medical necessity for the screening.
4. How G0108 Differs from Other Screening Codes
| Code | Description | Frequency | Patient Eligibility |
|---|---|---|---|
| G0101 | Routine pelvic and breast exam (low-risk) | Annually | Average-risk women |
| G0108 | High-risk pelvic and breast exam | As medically necessary | High-risk women |
| Q0091 | Pap smear collection only | Varies | All women (21-65) |
Key Differences:
-
G0108 is not routine—it requires documented risk factors.
-
Medicare covers G0108 more frequently than standard screenings.
5. Step-by-Step Guide to Billing G0108
Step 1: Verify Patient Eligibility
-
Confirm Medicare enrollment.
-
Document risk factors (family history, prior abnormalities).
Step 2: Perform the Screening
-
Conduct a clinical breast exam (CBE).
-
Perform a pelvic exam with or without a Pap smear.
Step 3: Submit the Claim
-
Use G0108 for the screening.
-
Attach supporting documentation (ICD-10 codes like Z80.3 for family history).
Step 4: Follow Up if Needed
-
If results are abnormal, proceed with diagnostic tests (e.g., biopsy, mammogram).
6. Common Documentation Requirements
To avoid claim denials, ensure proper documentation:
✔ Patient’s risk factors (e.g., genetic testing results, prior cancer).
✔ Medical necessity statement (why the patient needs G0108 instead of routine screening).
✔ Date and details of the exam (findings, recommendations).
7. Medicare and Insurance Coverage for G0108
-
Medicare Part B covers G0108 at 80% of the approved amount.
-
The patient is responsible for the remaining 20% unless they have supplemental insurance.
-
Private insurers may have different coverage rules—always verify beforehand.
8. Frequently Asked Questions (FAQs)
Q1: How often can G0108 be billed?
-
Medicare allows it as medically necessary, typically every 6-12 months for high-risk patients.
Q2: Can G0108 be billed with a Pap smear?
-
Yes, if medically necessary. Use Q0091 for the Pap smear collection.
Q3: What if a patient’s risk status changes?
-
Re-evaluate eligibility annually. If risk decreases, switch to G0101 for routine screening.
9. Conclusion
CPT Code G0108 plays a crucial role in early cancer detection for high-risk women. Proper documentation, billing accuracy, and patient education ensure compliance and optimal care. By understanding eligibility, billing steps, and coverage policies, healthcare providers can maximize the benefits of this essential screening service.
