What Medicare Pays vs. What You Might Be Charged

Category	Amount
Medicare Allowed Rate What Medicare approves for this service	$47.21
Typical Billed Amount What providers commonly charge	$75 – $300
Potential Markup How much more you might pay vs. Medicare rate	535% above Medicare

Why the difference? Providers set their own prices. Without insurance, you may be billed the full amount. Even with insurance, your co-pay is often based on the provider's charge — not the Medicare rate.

What CPT 17000 Means and When It's Used

CPT code 17000 is used when your dermatologist removes a precancerous skin lesion - essentially a spot on your skin that could turn into cancer if left untreated. This code specifically covers the destruction of the first lesion during your appointment.

Your doctor might use various methods to remove the precancerous tissue, such as freezing it with liquid nitrogen (cryotherapy), scraping it off, or using laser treatment. The specific removal method doesn't change the billing code - it's still CPT 17000 for that first lesion.

This procedure is considered preventive care since it stops potential skin cancer before it starts. Common types of precancerous lesions include actinic keratoses, which often appear as rough, scaly patches on sun-exposed areas like your face, hands, or arms.

What to Expect on Your Medical Bill

When you see CPT 17000 on your bill, you're being charged for the removal of one precancerous lesion. The Medicare reimbursement rate for this procedure is $47.21, but what you'll actually pay depends on your insurance coverage and where you received treatment.

Typical charges for CPT 17000 range from $75 to $300. The variation depends on factors like your geographic location, whether you went to a dermatologist's office or hospital, and your healthcare provider's standard rates. If you have insurance, you'll likely pay a copay or a percentage of the total cost after your deductible is met.

If your doctor removed multiple precancerous lesions during the same visit, you'll see additional codes on your bill. The second through fourteenth lesions are billed under CPT 17003, which has different pricing.

How to Verify Your Bill Is Correct

To check if your CPT 17000 charge is accurate, first confirm that you actually had a precancerous lesion removed during your visit. Look at your visit summary or discharge notes, which should mention the procedure and how many lesions were treated.

If the charge seems unusually high (significantly over $300), contact your healthcare provider's billing department to ask for an itemized explanation. Sometimes billing errors occur, such as being charged for multiple lesions when only one was removed, or being billed for a more expensive procedure code by mistake.

You can also call your insurance company to verify what they consider a reasonable charge for CPT 17000 in your area. If you're paying out of pocket, don't hesitate to ask your doctor's office about payment plans or whether they offer discounts for uninsured patients. Many practices are willing to work with patients on medical bills.

Frequently Asked Questions

How much does precancer removal cost with insurance?

With insurance, you'll typically pay a dermatology copay (often $20-50) or a percentage of the total cost after your deductible. Since this is often considered preventive care, some insurance plans may cover it at 100%.

Why was I charged CPT 17000 and CPT 17003 on the same visit?

CPT 17000 covers your first precancerous lesion removal, while CPT 17003 covers additional lesions removed during the same appointment. This is normal billing practice when multiple spots are treated.

Is CPT 17000 the same as mole removal?

No, CPT 17000 is specifically for precancerous lesions, not regular moles. Mole removal typically uses different codes like CPT 17110 for benign lesions, which may have different costs and coverage rules.
