TL;DR: The Centers for Medicare & Medicaid Services modified NCD 123 governing cryosurgery of the prostate, effective March 7, 2026. Here's what billing teams need to act on now.
CMS cryosurgery of the prostate coverage policy under NCD 123 Medicare draws a hard line between two clinical scenarios: primary treatment for localized prostate cancer and salvage therapy after radiation failure. The policy does not list specific CPT or HCPCS codes, so your team needs to work from clinical documentation and ICD-10 staging to support medical necessity. Get that documentation workflow locked down before the effective date of March 7, 2026.

CMS Cryosurgery of the Prostate Coverage Criteria and Medical Necessity Requirements 2026
NCD 123 is the National Coverage Determination governing Medicare coverage of cryosurgical ablation of the prostate (CSAP). CMS treats this procedure as safe, effective, and medically necessary — but only when the patient meets specific clinical criteria. Billing without those criteria documented is a fast path to claim denial.
Primary Treatment Coverage
CMS covers cryosurgery of the prostate as primary treatment for patients with clinically localized prostate cancer at Stages T1 through T3. That's the straightforward scenario. Your documentation needs to confirm localized disease and the staging — T1, T2, or T3 — before the claim goes out.
There's no ambiguity in the primary treatment rule. If the staging is documented and the disease is localized, the procedure meets medical necessity under this coverage policy. The clinical note needs to reflect that directly, not leave a reviewer guessing.
Salvage Therapy Coverage After Radiation Failure
This is where NCD 123 gets precise — and where most claim denials will happen. Cryosurgery of the prostate as salvage therapy is only covered when the patient meets all of the following:
| # | Covered Indication |
|---|---|
| 1 | The patient failed a trial of radiation therapy as primary treatment. |
| 2 | The patient meets at least one of these three conditions:
|
| 3 | Gleason score below 9 |
| 4 | PSA below 8 ng/mL |
All three conditions in criterion two are written as "or," not "and." One is enough. But criterion one — documented radiation failure — is non-negotiable. No radiation trial, no salvage coverage. Full stop.
Your clinical documentation must show the radiation therapy course, the evidence of failure, and the current staging and lab values. A claim for salvage CSAP without that sequence documented will not survive review.
Prior Authorization and Reimbursement Considerations
NCD 123 does not explicitly require prior authorization. That said, cryosurgical ablation of the prostate is a high-dollar procedure billed across inpatient and outpatient hospital settings, as well as under physician services. Each setting carries its own reimbursement structure and documentation requirements. Check with your Medicare Administrative Contractor for any local coverage determination that may layer additional requirements on top of this NCD before you submit.
CMS Cryosurgery of the Prostate Exclusions and Non-Covered Indications
The exclusions in NCD 123 are narrow but absolute. Miss them and you're looking at a denial with no path to appeal.
Salvage Therapy Before June 30, 2001
Cryosurgery of the prostate as salvage therapy is not covered for any services performed before June 30, 2001. This is a historical exclusion that rarely applies to current claims, but it matters if your team handles any late-filed or retroactive billing situations.
Salvage After Non-Radiation Primary Treatment
This is the most operationally significant exclusion. CMS does not cover cryosurgery as salvage therapy when the failed primary treatment was anything other than radiation. If a patient's first-line treatment was surgery, hormone therapy, or any other non-radiation approach, cryosurgery as a follow-on procedure is not covered under this policy.
The policy states this directly: salvage CSAP is only covered after the failure of radiation therapy. No other failed primary treatment qualifies. If your urology or oncology team is referring patients for salvage CSAP after non-radiation primary therapy, that needs to be flagged before the claim is built — not after it's denied.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Primary treatment for clinically localized prostate cancer, Stages T1–T3 | Covered | Not specified in NCD 123 | Documentation must confirm localized disease and T-stage |
| Salvage CSAP after radiation failure — Stage T2B or below | Covered | Not specified in NCD 123 | Radiation failure must be documented; staging required |
| Salvage CSAP after radiation failure — Gleason score below 9 | Covered | Not specified in NCD 123 | One qualifying condition sufficient; radiation failure still required |
| Salvage CSAP after radiation failure — PSA below 8 ng/mL | Covered | Not specified in NCD 123 | One qualifying condition sufficient; radiation failure still required |
| Salvage CSAP after failure of non-radiation primary treatment | Not Covered | Not specified in NCD 123 | Explicitly excluded; no other primary treatment type qualifies |
| Salvage CSAP for any services before June 30, 2001 | Not Covered | Not specified in NCD 123 | Historical exclusion; applies to retroactive or late-filed claims |
| Salvage CSAP with Gleason score of 9 or above, Stage above T2B, and PSA of 8 ng/mL or above (all three) | Not Covered | Not specified in NCD 123 | Patient must meet at least one qualifying condition in criterion two |
CMS Cryosurgery of the Prostate Billing Guidelines and Action Items 2026
The modified NCD 123 took effect March 7, 2026. If your team is still running documentation and charge capture processes built around older assumptions, here's what to do now.
| # | Action Item |
|---|---|
| 1 | Audit your documentation intake for CSAP claims. Pull every active or pending cryosurgical ablation of the prostate case and confirm whether it's being billed as primary treatment or salvage therapy. The distinction drives the entire coverage policy. Do this before submitting any claim dated on or after March 7, 2026. |
| 2 | Build a documentation checklist for salvage therapy claims. It needs three elements: proof of prior radiation therapy, proof of radiation failure, and at least one qualifying condition (Stage T2B or below, Gleason below 9, or PSA below 8 ng/mL). If any element is missing from the chart, hold the claim and go back to the clinical team. |
| 3 | Flag any salvage CSAP case where the primary treatment was not radiation. Set up a workflow with your urology and oncology billing contacts so these cases get caught before charge capture, not after. A denial on a surgical case is expensive to rework and harder to appeal than a denial on a diagnostic claim. |
| 4 | Contact your Medicare Administrative Contractor. NCD 123 sets the national floor, but your MAC may have a local coverage determination that adds requirements — specific diagnosis code ranges, documentation timeframes, or prior authorization steps. Get that information now, not when a claim comes back denied. |
| 5 | Confirm your charge capture reflects the correct place of service. Cryosurgery of the prostate bills under inpatient hospital services, outpatient hospital services incident to a physician's service, and physicians' services. Each setting has different billing guidelines and reimbursement rates. Make sure you're capturing the right setting for each case. |
| 6 | Train your coders on the T-stage and Gleason score documentation requirements. These aren't optional supporting details — they're the medical necessity criteria. If the physician's note doesn't include current staging and lab values, the coder can't build a defensible claim. Push this back to the clinical documentation side now. |
If your mix includes a high volume of salvage CSAP cases or complex oncology billing, loop in your compliance officer before submitting claims under the modified policy. The salvage criteria are specific enough that one misread can generate a pattern of denials that triggers a larger review.

CPT, HCPCS, and ICD-10 Codes for Cryosurgery of the Prostate Under NCD 123
Covered CPT Codes (When Selection Criteria Are Met)
NCD 123 does not list specific CPT or HCPCS codes. The policy defines coverage by clinical indication and medical necessity criteria, not by procedure code. Work with your coding team and MAC to confirm which codes apply to cryosurgical ablation of the prostate billing in your jurisdiction.
Not Covered / Experimental Codes
No specific codes are designated as non-covered or experimental in NCD 123. Coverage exclusions are tied to clinical scenarios — salvage after non-radiation therapy and services before June 30, 2001 — not to specific procedure codes.
Key ICD-10-CM Diagnosis Codes
NCD 123 does not enumerate specific ICD-10-CM codes. However, the policy's coverage criteria map directly to prostate cancer staging codes. Your coding team should confirm the appropriate malignant neoplasm of prostate codes that reflect T1–T3 staging for primary treatment claims, and recurrent disease codes for salvage therapy claims. Your MAC's local coverage determination will likely specify which ICD-10 codes support medical necessity for each scenario.
