For solo podiatrists, foot and ankle surgery groups, wound care practices and nursing home podiatry teams billing Medicare, Medicaid and commercial plans.
Podiatry revenue leaks in small, repeated claims. Debridement of six or more nails, 11721, pays $45.09 nationally under the 2026 Medicare fee schedule, and it denies as routine foot care when class findings or the Q7, Q8 or Q9 modifier are missing. Class finding Q modifiers were missing on 16% of Medicare routine foot care claims in our audit. Luxen’s certified coders handle podiatry coding, denials and diabetic shoe claims inside the system you already use.

Podiatry billing services manage coding, claims, denials and AR for foot and ankle care: routine foot care, nail and callus procedures, wound care, surgery and diabetic shoes. Medicare pays 11721 at $45.09 nationally in 2026, but only when a qualifying systemic condition is documented and, where class findings apply, a Q7, Q8 or Q9 modifier.
Service lines we bill through full-service medical billing: E/M visits, nail and callus care, avulsions and matrixectomies, wound debridement, injections, X-rays, surgery, diabetic shoes and orthotics.
One missing detail repeats at every podiatry visit. Amounts are 2026 Medicare national rates for clinicians not in a qualifying APM.
| Scenario | Codes | What goes wrong | $ at stake per claim | Luxen audit finding |
|---|---|---|---|---|
| Routine foot care on a systemic condition | 11721-Q8 | Q modifier or class findings missing, so the line denies as routine care | $45.09 (11721, office) | Class finding Q modifiers were missing on 16% of Medicare routine foot care claims |
| Nail care for a diabetic patient | 11720, G0127 | No date last seen or attending NPI in Item 19 | $32.73 (11720, office) | Item 19 date last seen or attending NPI was missing on 11% of claims for asterisked conditions |
| Paring and nail debridement on the same toe | 11055 with 11720-XS | Modifier used on the same distal phalanx | $32.73 (11720, office) | Coding and modifier errors caused 21% of denials |
| Unrelated visit during a bunion global | 28296, 99213-24 | Modifier 24 left off, so the visit bundles into post-op care | $95.19 (99213, office) | 19% of denied claims were never reworked or appealed |
| Diabetic shoes with a late certification | A5500, A5512, KX | Statement signed outside the timing window | Full shoe and insert claim | Certifying physician statements were missing or outside the 3-month window on 18% of diabetic shoe claims |

| Code | What it covers | Global days | Office | Facility |
|---|---|---|---|---|
| 11719 | Trimming of nondystrophic nails, any number | 0 | $14.36 | $6.68 |
| G0127 | Trimming of dystrophic nails, any number | 0 | $23.71 | $6.68 |
| 11720 | Debridement of nails, 1 to 5 | 0 | $32.73 | $12.69 |
| 11721 | Debridement of nails, 6 or more | 0 | $45.09 | $21.38 |
| 11055 | Paring or cutting of benign hyperkeratotic lesion, single | 0 | $70.14 | $13.69 |
| 11730 | Avulsion of nail plate, simple, single | 0 | $111.56 | $48.77 |
| 11750 | Excision of nail and nail matrix | 10 | $157.65 | $94.19 |
| 11042 | Debridement, subcutaneous tissue, first 20 sq cm or less | 0 | $132.60 | $55.78 |
| 28285 | Hammertoe correction | 90 | $548.44 | $370.75 |
| 28296 | Hallux valgus correction with distal first metatarsal osteotomy | 90 | $883.45 | $484.31 |
Nail, callus and debridement codes carry a 0-day global, 11750 carries 10 days, and bunion and hammertoe repairs carry 90 days plus one pre-op day. Inside those windows, use 24 for an unrelated E/M, 25 for a separately identifiable E/M on the procedure day, 57 for the decision for surgery, 58 for a staged procedure, 78 for an unplanned return to the procedure room and 79 for an unrelated procedure (CMS Global Surgery Booklet).
Nail trimming and cutting of corns and calluses are excluded from Medicare by Social Security Act section 1862(a)(13). They are covered only when a systemic condition, such as diabetes or peripheral vascular disease, makes nonprofessional care hazardous. Class findings in the exam note prove severity.
| Modifier | Findings required | Findings that count |
|---|---|---|
| Q7 | One Class A finding | Class A: nontraumatic amputation of the foot or an integral skeletal portion |
| Q8 | Two Class B findings | Class B: absent posterior tibial pulse; absent dorsalis pedis pulse; advanced trophic changes (three of: decreased hair growth, nail thickening, discoloration, thin shiny skin, rubor) |
| Q9 | One Class B and two Class C findings | Class C: claudication, cold feet or other temperature change, edema, paresthesias, burning |
Wellpoint Federal article A57759 requires one of these modifiers on 11055 to 11057, 11719 and G0127, and on 11720 and 11721 when coverage rests on a systemic condition. The Wellpoint Federal, CGS and WPS articles allow covered routine foot care once in 60 days.
For diabetes, chronic thrombophlebitis and neuropathies linked to diabetes, malnutrition, carcinoma, drugs and toxins, multiple sclerosis or uremia, an MD or DO must be actively managing the condition. CGS LCD L34246 counts a visit in the prior six months. Item 19 of the CMS-1500 carries the date last seen and the attending physician NPI (Claims Processing Manual, Ch. 26). In our audit, Item 19 date last seen or attending NPI was missing on 11% of claims for asterisked conditions.
For an ambulatory patient, mycotic nail debridement is covered when the note shows mycosis plus marked limitation of ambulation, pain or secondary infection from the thickened nail, no more often than every 60 days unless more frequent need is documented (42 CFR 411.15(l)).
Care that meets no exception is statutorily excluded: no ABN is required and the line carries GY. An early visit without documented need is a medical necessity denial, so get an ABN first and bill with GA (CMS MLN006266). Those balances move to patient billing.
Depth shoes (A5500), custom molded shoes (A5501) and inserts (A5512 to A5514) are DME MAC claims under policy article A52501.
Supplying shoes needs DMEPOS billing privileges under 42 CFR 424.57, which our credentialing team sets up. In our audit, certifying physician statements were missing or outside the 3-month window on 18% of diabetic shoe claims.
NCD 70.2.1 covers a foot evaluation with patient education every six months for diabetic neuropathy with loss of protective sensation, diagnosed with a 5.07 monofilament, unless a foot care specialist saw the patient in between. Bill G0245 initially ($65.47 office) or G0246 for follow-up ($38.75), with G0247 for same-day routine foot care (CMS Transmittal R498CP).
Supportive devices for the feet are excluded by section 1862(a)(8), except shoes built into a leg brace and diabetic shoes. Billed without KX, L3000 to L3649 deny as statutorily excluded (DME MAC article A52481). Commercial orthotic benefits vary, so coverage is verified before casting.
Diabetes is an asterisked condition: routine care is covered only when an MD or DO actively manages it and the note shows severity, usually through class findings (CGS LCD L34246). Without that, 11721 at $45.09 is lost at every 60-day visit, about $270 a patient a year. In our audit, class finding Q modifiers were missing on 16% of Medicare routine foot care claims.
Eight weeks is 56 days, and the limit is every 60 days unless the physician documents a need for more (42 CFR 411.15(l)). An early visit without that note denies, and without an ABN the balance cannot move to the patient. The top three denial reasons accounted for 58% of denied dollars in the average practice we reviewed.
The certifying physician must be an MD or DO managing the diabetes (DME MAC article A52501). A podiatrist-signed statement fails the whole shoe and insert claim. In our audit, certifying physician statements were missing or outside the 3-month window on 18% of diabetic shoe claims.
NCCI does not allow 59 or XS on the 11055 and 11720 edit when both are on the same distal phalanx (NCCI Policy Manual, Ch. III). Used there, the $32.73 debridement line becomes an overpayment. Coding and modifier errors caused 21% of denials in our claim audit.
We run the revenue cycle from eligibility to zero balance inside the practice management system you already use. How full-service billing works.
Certified coders review charges against your documentation and payer rules before the claim goes out, so the denial is prevented rather than appealed. Medical coding.
Aged and denied claims are worked to resolution, then the upstream cause is fixed so the same claims stop coming back. Denials and AR recovery.
Benefits are verified and authorizations secured before the appointment, which is the cheapest place in the cycle to stop a denial. Eligibility and prior authorization.
Statements, balance questions and payment plans are handled by the same team that worked the claim. Patient billing.
Payer enrollment and re-credentialing are tracked through to approval, so a lapsed credential never quietly stops payment. Credentialing.
A HIPAA-trained front-office assistant working inside your EHR on calls, scheduling, intake and referrals, alongside the billing team. Medical virtual assistant.
Podiatry practices run systems such as ModMed, TRAKnet, eClinicalWorks, NextGen, AdvancedMD or athenahealth, with digital X-ray software beside the EHR and DME MAC portals for shoe claims. Surgical cases add the ASC or hospital record. We work inside whichever system you run, with no migration and no change to how podiatrists document; we need user access, your fee schedules and a signed BAA.

For a worked recovery example, read the dental practice case study.
Routine foot-care claims were being denied because the required clinical findings were not consistently included in the note. Luxen introduced a focused documentation checklist, reduced denials from 21% to 6%, and recovered $18,900.
Practice Owner, multi-provider podiatry clinic
Braces and custom orthotics were dispensed in the clinic, but proof of delivery and the billing charge did not always match. Luxen reconciled the records and captured $27,600 in missed equipment revenue.
Operations Manager, podiatry and foot surgery practice
Full engagements are written up in our dental practice case study and our ambulance billing case study.
Podiatry claims are frequent and low dollar, and shoe claims age at a separate DME MAC, so review these monthly. Benchmarks come from Luxen data.
| KPI | Why it matters in podiatry | Luxen benchmark |
|---|---|---|
| First-pass denial rate | Q modifier, Item 19 and frequency edits show here first | Across 38 client practices, first-pass denial rate fell from 14.2% to 6.1% within 90 days of onboarding |
| Days in AR | Surgery and DME MAC claims age on separate clocks | Median days in AR dropped from 54 to 33 within 120 days |
| Denials left unworked | Low-dollar nail care denials get written off | 19% of denied claims were never reworked or appealed |
| Underpayments | Contracted surgery and wound care rates | Underpayments against contracted rates appeared on 7.8% of paid claims |
| Timely filing | Medicare allows 1 calendar year from the date of service (42 CFR 424.44) | Timely filing caused 6% of denials, and only 4% of those were recovered |
Practices that reviewed AR ageing monthly carried 12 fewer days in AR. Our denial and AR recovery team works that list by dollar value and deadline.
Under Florida Statutes section 627.6131(18), insurers must send overpayment claims to podiatrists within 12 months of payment, against 30 months under the general rule. See our Florida medical billing rules.
3% to 6% of collections
Luxen's pricing generally falls between 3% and 6% of collections, depending on claim volume, specialty, payer mix, and how much of the revenue cycle your practice hands over.
Higher-volume practices usually land toward the lower end. Smaller or more complex practices land higher because there is more work per account. There is no setup fee and no exit fee, and the agreement runs month to month with 30 days notice.
A lower fee attached to weak billing is still expensive. The number that matters is what your collections do after you hire someone.
Luxen charges 3% to 6% of collections, set by claim volume, service mix and aged AR. Month to month, 30 days notice, no setup or exit fee.
Example: a two-podiatrist practice collecting $70,000 a month.
| Service line | Monthly collections | Luxen at 3% | Luxen at 6% | In-house at 7.9% |
|---|---|---|---|---|
| Office visits and foot care | $38,000 | $1,140 | $2,280 | $3,002 |
| Surgery (office, ASC and hospital) | $22,000 | $660 | $1,320 | $1,738 |
| Diabetic shoes and orthotics | $10,000 | $300 | $600 | $790 |
| Total per month | $70,000 | $2,100 | $4,200 | $5,530 |
| Total per year | $840,000 | $25,200 | $50,400 | $66,360 |
The in-house column uses our finding that fully loaded in-house billing cost 7.9% of collections for practices under $2M, across 96 practices that shared payroll data. Open biller roles took a median 67 days to fill.
| Partner type | Podiatry coding depth | Shoe and DME claims | Cost basis |
|---|---|---|---|
| In-house biller | Depends on one person | Depends on staff training | Salary, benefits and software |
| Generalist billing company | May miss class finding and asterisk rules | May not bill the DME MAC | Percentage of collections |
| Specialty billing company | Knows podiatry codes | Varies | Percentage or per-claim fee |
| EHR vendor RCM | Tied to that vendor’s system | Depends on the vendor | Percentage plus software contract |
| Luxen | Certified coders, foot care edits before submission | Separate DME MAC queue | 3% to 6%, month to month |
To see the wider market, compare medical billing companies by state.
A 30-minute look at your AR ageing, denial reasons and payer mix. You leave knowing what is recoverable, what we would work first and what it would cost.
We sign a business associate agreement before anyone touches your system. Your named team then works inside the practice management system and clearinghouse you already use. Nothing is migrated, and claims are being worked within two weeks of the signed BAA.
Aged and denied claims come first because that is revenue you have already earned. Most practices see the first recovered payments inside three weeks.
Once the backlog is moving, we take over the agreed part of the daily cycle: eligibility, coding review, submission, posting, denials and patient balances.
You know who owns your claims. The team works inside the practice management system and EHR you already run, with no migration.
Claims are coded by certified coders against your documentation and payer rules. Automation handles the repetitive checks so people spend their time on the claims that need judgment.
We sign a business associate agreement before accessing protected health information, and access is limited to the named people on your account.
We look at your AR ageing, volume, payer mix and denial profile first, then tell you what we believe is recoverable and what it would cost.
A billing company is a poor fit if you are not willing to share visibility into your billing, if the vendor uses a rotating pool of people who never learn your practice, or if it cannot explain why your claims are being denied. Be wary of anyone promising large collection increases before they have seen your AR ageing. The right partner makes your revenue cycle more visible, not less.
Q8 tells Medicare the exam found two Class B findings, such as absent posterior tibial and dorsalis pedis pulses or advanced trophic changes. It supports routine foot care codes such as 11721 and G0127 for a patient with a qualifying systemic condition. Q7 means one Class A finding, and Q9 means one Class B plus two Class C findings.
Under the 2026 national fee schedule for clinicians outside qualifying APMs, an established patient visit, 99213, pays $95.19 in the office, debridement of six or more nails, 11721, pays $45.09 and a single nail avulsion, 11730, pays $111.56. Routine foot care pays only when a coverage exception is documented.
We start after a signed BAA and work inside your current EHR, so nothing is migrated. Median time from signed BAA to first claims worked was 9 business days, and first recovered payments arrived a median of 17 days after work began. Oldest claims come first, because Medicare timely filing closes 1 calendar year after the date of service.
Yes. We work inside your existing system, including ModMed, TRAKnet, eClinicalWorks, NextGen, AdvancedMD and athenahealth, plus DME MAC portals for shoe claims. We need user access, your fee schedules and a signed BAA, and podiatrists keep documenting the way they do now.
Yes, when the visit is significant and separately identifiable, with modifier 25 on the E/M code. Nail debridement codes 11720 and 11721 carry a 0-day global, so the decision to debride and the brief exam before it are part of the procedure. A separate problem worked up that day, such as a new wound or ankle pain, can support 99213 with modifier 25.
Thirty minutes, no deck and no fee. We look at what is sitting past 90 days and where your denials cluster, and you leave knowing what is recoverable, what we would work first, and what it would cost.
