Is it cheaper per nail to have all nails done at once under 11721?

Yes. If you have 6 or more affected nails, one 11721 charge ($83 average) is cheaper than two separate 11720 visits ($58 x 2 = $117). The per-nail cost drops significantly when all are done together. If you have 6+ nails that need debridement, do them all in one session.

CPT (Current Procedural Terminology) codes are five-digit numbers that describe every medical service or procedure. Your doctor, hospital, and insurance company use them to communicate exactly what was done. Every line on your medical bill has a CPT code, and knowing the code lets you look up what Medicare pays for that same service.

Why do providers charge so much more than Medicare pays?

Providers set their own "chargemaster" prices, which are essentially list prices. Medicare pays a fixed rate based on the resources each service actually requires (the RVU system for procedures, or the Clinical Lab Fee Schedule for lab tests). Commercial insurers typically pay 150% to 250% of Medicare rates. Uninsured patients are often billed the full chargemaster price, which can be 2x to 30x what Medicare pays.

Can I use Medicare rates to negotiate my bill?

Yes. Medicare rates are the closest thing to a "fair price" benchmark in U.S. healthcare. When negotiating, ask the provider what they accept from Medicare for the same CPT code. Most providers will accept 150% to 200% of Medicare for cash-pay patients, which is still far less than their chargemaster price. Many hospital financial assistance policies also use a multiple of Medicare as their discount floor.

How are Medicare rates calculated?

For most procedures, Medicare uses the Resource-Based Relative Value Scale (RBRVS). Each CPT code gets three RVU components: Work (physician time and skill), Practice Expense (overhead), and Malpractice. These are multiplied by geographic adjustment factors (GPCIs) and a conversion factor ($33.4009 in 2026). Lab tests (80000-89999 range) use a separate Clinical Laboratory Fee Schedule with flat national rates.

CPT 11720

Debridement of Nails, 1-5 Nails

CPT 11720 covers toenail trimming and debridement for 1 to 5 thickened or fungal nails. It is one of the most common podiatry codes, used over 717,000 times per year for Medicare beneficiaries. Providers charge an average of $58.37, and Medicare pays $32.73 in an office setting (1.8x markup). The critical coverage issue is the same as other routine foot care: Medicare only pays when you have a qualifying systemic condition. Without one, you pay 100% out-of-pocket.

How the Medicare Rate Is Calculated

Medicare values every procedure using Relative Value Units (RVUs) across three components, then multiplies by a national conversion factor of $33.4009 (2026). Here is the exact math for CPT 11720:

Component	What It Covers	Office (Non-Facility)	Hospital (Facility)
Work RVU	Physician time and skill for debridement	0.39	0.39
Practice Expense RVU	Instruments, supplies, staff	0.55	0.04
Malpractice RVU	Professional liability insurance	0.04	0.04
Total RVU		0.98	0.47
x $33.4009	2026 conversion factor	$32.73	$15.70

Medicare Rate by State

Medicare adjusts the national rate by location using Geographic Practice Cost Indices (GPCIs). Here is how the 11720 rate varies across states in the office setting:

Sample State Rates (Office Setting)

State	Medicare Pays	Avg. Charge	Markup
Texas (Austin)	$26.73	$58.37	2.2x
California (Los Angeles)	$28.36	$58.37	2.1x
New York (Manhattan)	$28.72	$58.37	2.0x
Florida (Fort Lauderdale)	$27.02	$58.37	2.2x
Ohio	$24.63	$58.37	2.4x
Mississippi	$23.59	$58.37	2.5x
Arkansas	$23.35	$58.37	2.5x
Alaska	$32.13	$58.37	1.8x

Rates shown are for the non-facility (office) setting using 2026 GPCIs and the $33.4009 conversion factor. The average provider charge of $58.37 is the 2023 national average from CMS utilization data. Actual charges vary by provider.

Coverage Rules and 11720 vs 11721

The same Medicare coverage rules apply to nail debridement as to callus removal. Medicare considers this "routine foot care" unless you have a qualifying systemic condition.

Coverage requirement: Medicare only covers 11720 when you have a qualifying systemic condition (diabetes with neuropathy, peripheral vascular disease, or similar). Without documentation of a qualifying condition, the claim will be denied and you pay 100% out-of-pocket. Ensure your podiatrist documents the qualifying diagnosis at every visit.

11720 vs 11721: Which Code Applies?

Code	Nails	Avg. Charge	Medicare (Office)	Per-Nail Cost
11720	1-5 nails	$58.37	$32.73	$11.67-$58.37
11721	6+ nails	$83	$47	$8.30-$13.83

Cost math for patients with 6+ affected nails: If you have 6 or more nails that need debridement, one 11721 visit ($83) is significantly cheaper than splitting them into two 11720 visits ($58 x 2 = $117). The difference is $34 in average charges. If all affected nails need attention, have them all done in one session under 11721.

Common Billing Problems with 11720

Office visit billed on top of nail debridement

Some podiatrists bill an office visit code (99211 to 99213) in addition to 11720 for the same appointment. If nail debridement is the sole service performed and no separate evaluation or management occurred, this additional charge may not be justified. A brief assessment of the nails before debridement is part of the procedure itself, not a separate service. If you see both charges on your bill and the only thing done was nail trimming, ask for clarification.

Denied for missing qualifying condition documentation

If your claim was denied but you have a qualifying condition (diabetes with neuropathy, PVD, etc.), the issue is likely documentation or coding. Ask your podiatrist to resubmit with the correct qualifying diagnosis code. Medicare requires the systemic condition to be linked to the claim as a justifying diagnosis. A simple "diabetes" code (E11.9) may not be sufficient. It needs to specify the complication (e.g., E11.42 for diabetes with polyneuropathy).

Splitting nails across visits to bill 11720 twice

If you have 6 or more affected nails but your podiatrist only does 5 per visit (requiring two visits), you end up paying for two 11720 charges ($117 total) instead of one 11721 ($83). This costs you $34 more and requires an extra appointment. If all nails need debridement, ask your podiatrist to do all of them in one session and bill 11721.

Frequently Asked Questions

How much does toenail debridement cost?

Toenail debridement for 1 to 5 nails (CPT 11720) costs an average of $58.37 at the provider's billed charge. Medicare pays $32.73 in an office setting. For 6 or more nails (CPT 11721), the average charge is $83. If you are paying out-of-pocket because you lack a qualifying systemic condition, many podiatrists offer a cash-pay rate of $40 to $60 for routine nail care.

Does Medicare cover toenail trimming?

Medicare covers toenail debridement (CPT 11720) ONLY when you have a qualifying systemic condition such as diabetes with peripheral neuropathy, peripheral vascular disease, or other conditions that make routine nail care medically necessary. Without a qualifying diagnosis, Medicare considers this routine foot care and the claim will be denied. You are responsible for the entire cost.

Is it cheaper per nail to have all nails done at once?

Yes. If you have 6 or more affected nails, having them all done in one session under CPT 11721 ($83 average) is cheaper than splitting them across two visits billed as CPT 11720 ($58 x 2 = $117). You save $34 in average charges and avoid an additional office visit copay. Always ask your podiatrist to do all affected nails in one session if clinically appropriate.

Can a podiatrist bill an office visit on top of nail debridement?

Some podiatrists bill an office visit (99211 to 99213) in addition to 11720. This is only appropriate when a distinct, separately identifiable evaluation and management service occurs beyond the nail debridement itself. If your only reason for the visit is nail care and no other medical issues were evaluated, the additional office visit charge may not be warranted. Ask the billing department to explain what the separate E/M service was for.
