Cryotherapy CPT Codes: The Complete 2026 Billing Guide for Every Code Family

There Is No Single Cryotherapy CPT Code

Cryotherapy describes a technique. The cryotherapy CPT code you report follows the tissue you destroyed. Liquid nitrogen, CO2 slush, and argon gas all route through the same code families, so the cold agent never picks the code for you.

Five families cover most skin cases: premalignant lesions, benign lesions, skin tags, acne, and therapeutic cold packs. Body-site and organ cryoablation sit in separate ranges that no dermatology destruction code reaches.

A wart, an actinic keratosis, and a skin tag can all get frozen in the same visit with the same cryogun. Each one bills under a different code family. Each one carries its own unit rule.

Two facts resolve the cryotherapy CPT code question on skin claims: lesion type and lesion count. Pull both from the note before you open the code book. Everything below builds out that table.

Master Table: Every Cryotherapy CPT Code in 2026

Use this as a working reference at the charge-entry desk. Every rate below traces to the 2026 Medicare conversion factor, and your locality adjustment will move the final number up or down.

Two Medicare conversion factors apply in 2026. Non-qualifying clinicians bill against $33.4009, and clinicians who qualify as APM participants bill against $33.5675. Any fee estimate your team built on a single 2025 factor now produces the wrong number, and the CMS 2026 RVU files carry the component values behind it.

Category III codes carry no assigned RVUs. Payers set payment at their own discretion instead of pulling from a fee schedule, and that applies to 0440T, 0441T, 0442T, 0881T, and 1040T.

Premalignant Lesions: How to Bill 17000, 17003, and 17004

Actinic keratoses are premalignant. That one word decides the family. When the note says actinic keratosis, you’re in the 17000 series and nowhere else, and your reimbursement runs on lesion count rather than lesion size or location.

The Unit Rule That Costs Practices the Most Money

Report 17000 as 1 unit for the first lesion. Report 17003 in units, one per lesion, for lesions 2 through 14. Report 17004 as a single unit when the provider treats 15 or more in one session.

Do not report 17000 or 17003 with 17004.

Most billers report 17003 once instead of in units. On a 10-lesion session that produces 17000 x1 and 17003 x1, which pays for 2 lesions. The practice writes off the other 8 without ever seeing a denial.

Three Worked Examples

The middle row trips people because the add-on count equals total lesions minus one. You billed the first lesion under 17000, so 10 lesions produce 9 units of 17003.

Your chart needs a lesion count and a lesion type. A note reading “multiple AKs treated with liquid nitrogen” won’t support 17003 units when an auditor asks for them.

Why 15 Actinic Keratoses Pay More Than 14

More line items means more money on most claims. On this code family it runs backward, because the threshold code outpays the entire stack it replaces.

At 15 lesions, 17004 carries 2.08 work RVUs against 0.98 for 17000 plus 17003 x13. One additional lesion moves the claim from an add-on stack to a standalone code worth more than twice the work value. Same session, same liquid nitrogen, same provider time.

Practices treating patients near that threshold should count with care and document the count in the note. Reporting 17004 at 15 lesions follows the code assignment the AMA built for that lesion volume.

Some MACs review high-volume destruction claims. An accurate lesion count in the chart is what carries you through that review.

Benign Lesions: When to Use 17110 and 17111

Warts, molluscum contagiosum, and seborrheic keratoses are benign, so they code to 17110 and 17111. The 17000 series and 17110 use opposite unit structures, and billers get tripped up by that gap more than by anything else on a derm claim.

17110 Covers the Whole Session, Not Each Lesion

Report 17110 as 1 unit for 1 to 14 lesions. No add-on code exists. Freezing 1 wart and freezing 14 warts both produce a single unit, and 17111 replaces 17110 at 15 or more.

Do not report 17110 and 17111 together.

Billers who learned the 17000 series first try to stack units on 17110. The code doesn’t work that way. One session gets one unit, whatever the count inside the range.

Three Exclusions Built Into 17110

The descriptor names two exclusions and the code family supplies a third. Skin tags belong to 11200 and 11201. Cutaneous vascular proliferative lesions belong to 17106 through 17108. Premalignant lesions belong to the 17000 series. The AAPC CPT 17110 code page carries the full descriptor language.

Code 17110 carries a 10-day global period, so the procedure payment covers related follow-up visits inside that window. Our G2211 and global periods guide covers how global periods interact with same-day add-on codes.

The AMA revised the short descriptors for 17106, 17107, 17108, 17110, and 17111 effective January 1, 2026. A chargemaster still pulling last year’s short descriptor creates estimate mismatches your front desk hears about first.

Seborrheic vs Actinic Keratosis: Same Word, Different Code Family

Both conditions carry the word keratosis. They sit in different code families, and mixing them produces an automatic denial.

The failure starts in dictation. A provider says “keratosis” without the qualifier, the biller defaults to whichever family the practice uses most, and the claim goes out with L57.0 sitting on 17110. Our CO-11 diagnosis mismatch denials guide walks the full resolution path.

Fix this in the template rather than in the coding queue. Require actinic or seborrheic as a completed field before the destruction code populates.

Pairing L57.0 with 17110 does more than deny one claim. It opens documentation review across every destruction claim you filed in that period.

Skin Tags: Why Freezing One Still Bills as 11200

Use CPT 11200 for the removal of the first 1 to 15 skin tags. For each additional 10 skin tags, or part thereof, report add-on code 11201. These codes apply regardless of removal method, including cryotherapy, excision, ligation, and electrocautery.

Freezing a skin tag still bills as 11200. Coding it as 17110 triggers a mismatch denial because 17110 excludes skin tags inside its own descriptor, a point certified coders debate at length in the AAPC skin tag coding discussion. The removal method never changes the family.

Code 11201 is an add-on reported per each additional group of 10 skin tags, not a threshold code for 16 or more. That error sits inside at least one major answer engine right now, and billers who trust it under-report their units.

Many payers treat skin tag removal as cosmetic unless the chart documents irritation, bleeding, or functional interference. The cosmetic pathway gets its own section below.

CPT 17340 Is an Acne Code, Not a Wart Code

CPT 17340 describes cryotherapy for acne using CO2 slush or liquid nitrogen. The code sits in the Other Procedures subsection of the integumentary system, outside the lesion destruction range, as the AAPC CPT 17340 code page confirms.

Several widely-read billing resources list 17340 as the wart cryotherapy code. It isn’t. Submitting 17340 for a wart destruction produces a denial, because the code carries an acne indication and its own coverage rules.

Warts route to 17110 or 17111. Actinic keratoses route to the 17000 series. Skin tags route to 11200. Acne cryotherapy is the only service 17340 describes, which makes it the narrowest cryotherapy CPT code in the entire set.

Multiple payers list 17340 as non-covered, including state Medicaid programs that publish it in their procedure code manuals. Run the coverage check before the service rather than after the denial.

Billing an E/M Visit on the Same Day as Cryotherapy

You can bill 99213 with 17110 on the same date. Modifier 25 goes on the E/M line, never on the procedure. Payment turns on whether that E/M stands on its own once you strip the procedure out of the encounter.

When Modifier 25 Holds Up

Apply one test before you append anything. Remove the procedure from the visit and ask whether the E/M still bills by itself. A patient in for a psoriasis flare who also gets 3 actinic keratoses frozen gives you two distinct services.

Your E/M note needs its own history, exam, and decision-making, written apart from the procedure note. When a reviewer can’t tell where one ends and the other starts, the modifier fails on first review. Our Modifier 25 billing guide covers the documentation standard in full.

The Decision Visit Trap

Medicare contractor policy treats an E/M performed the same day or the day before a dermatologic procedure, when it exists only to decide on that procedure, as not separately payable. Look, decide, freeze counts as one service.

G2211 adds a 2026 conflict. CMS won’t pay G2211 alongside an E/M carrying modifier 25 when the paired procedure has a 0-day global period, and that catches a long list of same-day skin procedures.

Modifier 25 in dermatology draws sustained payer scrutiny. A practice appending it to most destruction encounters should expect a documentation request at some point.

If modifier 25 denials keep landing across your destruction claims, our dermatology billing support team reads the documentation pattern before anything gets resubmitted.

Biopsy and Destruction on the Same Date: The NCCI Rules

Providers biopsy one lesion and freeze another in the same visit all the time. Payment on both depends on whether your record proves they were different lesions.

Lesion removal codes include tissue sampling from the same lesion at the same encounter. Biopsy codes 11102 through 11107 aren’t separately reportable when the biopsy and the destruction target one lesion, and our pathology specimen billing rules guide covers how specimen containers drive unit counts.

NCCI procedure-to-procedure edits pair 11102, 11104, and 11106 with 17000 and 17004. When the edit allows a bypass, modifier 59 or an X-modifier applies, but only for separate lesions or separate encounters. Our CO-236 NCCI edit resolution guide maps the full modifier framework.

Modifier 59 is not a payment button. Your chart has to name two lesions.

Reach for XS instead of 59 when the lesions sit on anatomically separate structures. Payers reviewing modifier 59 volume read that specificity as a good-faith signal.

CMS updates PTP edits every quarter. A pair that bypassed cleanly last quarter can flip, so your scrubber logic needs a refresh schedule instead of a one-time build.

MUE limits sit on top of the bundling rules, and CMS keeps some MUE values confidential. High lesion counts can hit both edits on a single claim.

Physical Therapy Cold Packs and the 97010 Bundling Rule

Physical therapy uses cryotherapy as a cold pack, which makes it a modality rather than a destruction procedure. CPT 97010 covers the application of hot or cold packs to one or more areas.

CPT 97010 is a bundled service under the Medicare Physician Fee Schedule. CMS treats it as part of the other services you delivered that day. You can report it. You won’t collect a separate payment for it.

CPT 97016 describes vasopneumatic device therapy, which delivers intermittent compression rather than cold. Some devices include a cooling element, and the code still pays for the compression. 97016 is not a cryotherapy code.

Ice massage requires active clinician application, so it falls outside 97010. When a therapist performs the massage, look at the timed manual therapy codes instead.

Bundled services still need charting. Note the modality, the site, and the clinical reason, because that record supports your plan of care when a reviewer pulls the chart. Our physical therapy CPT billing guide covers the evaluation and modality codes together.

Cryoneurolysis and Nerve Cryoablation: 0440T Through 0442T

No permanent CPT code exists for cryoneurolysis. Practices default to nerve destruction codes, and at least one Medicare contractor has ruled that those codes don’t apply.

Codes 64640 and 64624 require destruction of the target nerve. Temporary cryoneurolysis systems don’t destroy the nerve, which is why that contractor found both codes inappropriate for Medicare billing on the technology.

Category III codes carry no assigned RVUs. Payers decide payment themselves, so secure prior authorization and written coverage confirmation before the service instead of arguing after the denial.

Contractors may request records case by case for medical necessity. Your operative note needs the image guidance and the nerve location in writing.

Cryotherapy CPT Codes by Body Site

Outside the skin, cryotherapy codes follow the anatomic site. A dermatology destruction code never applies to an organ or a tumor, however similar the technique looks in the room.

Gynecologic and Urologic Sites

Watch the anal code. 46916 is the cryosurgery code, and 46900 covers chemical destruction. Several circulating cryosurgery reference sheets list 46900, which sends a cryosurgery claim out under the wrong method.

Ophthalmic Cryotherapy Codes

Several ophthalmic cryotherapy codes carry NCCI edits against related retinal procedures. Check the pair before you bill a cryotherapy code alongside photocoagulation or vitrectomy on the same eye, and confirm the descriptor on the AAPC CPT 66720 listing.

Pulmonary, Organ, and Tumor Cryoablation

Code 1040T is new. The AMA released it on December 30, 2025, and it went live July 1, 2026. It describes flexible bronchoscopy with bronchial cryotherapy of 1 lung, including the trachea when performed, and the AMA Category III long descriptors carry the complete wording.

Each of these families sits with a different specialty team, different payer rules, and a different denial fingerprint. Our specialty billing services assign coders by discipline for exactly that reason.

Cosmetic Lesion Removal: Z41.1 and Modifier GY

Coverage on lesion destruction turns on medical necessity. The same wart frozen for irritation and bleeding gets paid. Frozen because the patient dislikes how it looks, it doesn’t.

Report ICD-10 code Z41.1 on claims for benign skin lesion removal performed for cosmetic reasons. When the patient wants a formal denial for secondary coverage, modifier GY signals a statutorily excluded service.

Your note needs the clinical reason in writing: bleeding, irritation, pain, functional interference, or concern for malignancy. A chart saying the patient disliked the appearance sets up the denial before the claim leaves your office.

Handle cosmetic destruction as a financial conversation before the visit. Patients need the estimate and the payment arrangement up front, not a surprise statement six weeks later.

Practices running high cosmetic destruction volume on thin medical necessity documentation are the ones who draw retrospective review.

When cosmetic denials start landing on claims that should have been covered, the fix sits in the documentation template, and that’s where our lesion denial recovery work starts.

Whole-Body Cryotherapy Has No CPT Code

Whole-body cryotherapy has no CPT code and no payer coverage. The chamber sessions offered in recovery studios and wellness centers are a cash-pay service, and no code describes them as a billable medical procedure.

Some practices reach for 97039 as an unlisted modality or 97010 as a cold application. Neither works. 97010 is bundled and describes a localized cold pack, and an unlisted code requires documentation the service can’t support.

Price the service, disclose it as non-covered before the session, and keep it out of your claims workflow. Mixing cash-pay wellness into insurance billing creates audit exposure your practice doesn’t need.

Localized cryotherapy that destroys tissue is a billable procedure. Whole-body cold exposure for recovery is a wellness service. The distinction is tissue destruction, not temperature.

Cryotherapy Coding Changes That Took Effect in 2026

The 2026 Changes That Affect Your Claims

Two Medicare conversion factors took effect in 2026. Non-qualifying clinicians bill against $33.4009, and qualifying APM participants bill against $33.5675. A fee estimate built on a single 2025 factor now produces the wrong number.

The AMA revised short descriptors for 17106, 17107, 17108, 17110, and 17111 effective January 1, 2026. Chargemasters and patient estimate tools still pulling the old descriptor create mismatches downstream.

Code 1040T went live July 1, 2026 as a Category III code for flexible bronchoscopy with bronchial cryotherapy. The AMA released it inside the December 30, 2025 update, alongside 27 other new Category III codes covered in the AAPC Category III code update.

CMS updates NCCI procedure-to-procedure edits and MUE tables every quarter. Scrubber logic built once and left alone falls out of alignment inside a single quarter, the same way stale E/M values do. Our 2026 E/M reimbursement changes guide tracks the visit-level side of the same update cycle.

Cryotherapy CPT Code FAQ

What is the CPT code for cryotherapy of warts?

Report 17110 for 1 to 14 benign lesions in one session, and 17111 for 15 or more. Do not use the 17000 series for warts. Those codes are restricted to premalignant lesions.

Does CPT 11200 include cryotherapy?

Yes. CPT 11200 covers skin tag removal by any method, including cryotherapy, excision, ligation, and electrocautery. The removal method never changes the code.

What is the description of CPT code 17340?

CPT 17340 describes cryotherapy for acne using CO2 slush or liquid nitrogen. It does not apply to warts, skin tags, or skin cancer lesions, and multiple payers list it as non-covered.

What is the difference between CPT 17000 and 17110?

CPT 17000 covers premalignant lesions and bills per lesion using add-on code 17003. CPT 17110 covers benign lesions and bills as one session unit for 1 to 14 lesions.

Can you bill 99213 with 17110?

Yes, with modifier 25 on the E/M line, when the visit is significant and separately identifiable from the procedure. A visit that exists only to decide on the procedure is not separately payable.

Does 17110 need a modifier?

Not by itself. Modifier 25 goes on the E/M when you bill one the same day. Modifier 59 or XS applies when a separate lesion received a distinct procedure during the same encounter.

Cryotherapy coding fails in predictable places: lesion counts that miss the units billed, modifier 25 that cannot stand on its own, and diagnosis codes pointing at the wrong family. If your destruction claims keep coming back, our multi-specialty billing services and solo practice billing services teams start with the denial pattern instead of the resubmission.
