TL;DR: The Centers for Medicare & Medicaid Services modified NCD 123 governing cryosurgery of the prostate, effective March 7, 2026. Here's what changes for billing teams.
CMS updated its cryosurgery of the prostate coverage policy under NCD 123 Medicare. This National Coverage Determination covers cryosurgical ablation of the prostate (CSAP) as both primary treatment for localized prostate cancer and as salvage therapy after radiation failure. The policy does not list specific CPT or HCPCS codes, so your billing team needs to verify applicable procedure codes through your MAC and internal charge description master. If your practice or facility bills for prostate cancer treatment—urologists, radiation oncologists, and outpatient hospital departments especially—this policy sets the floor for what Medicare covers.

CMS Cryosurgery of the Prostate Coverage Criteria and Medical Necessity Requirements 2026
CMS coverage under NCD 123 breaks into two distinct clinical situations. Understanding which bucket your patient falls into determines whether the claim pays or denies. Get this wrong and you're looking at a claim denial with very little room to appeal.
Primary Treatment — Covered
Cryosurgery of the prostate as primary treatment is covered when the patient has clinically localized prostate cancer at Stages T1, T2, or T3. CMS considers this medically necessary and appropriate for these patients. There is no salvage therapy context here—the patient has not had prior radiation, and CSAP is the intended curative approach.
The medical necessity standard is straightforward for primary treatment. Stage the patient correctly, document it in the record, and your claim has a solid foundation. Where billing teams get into trouble is when they bill primary treatment codes for patients who actually received salvage therapy, or vice versa. Documentation in the chart needs to match what you're billing.
Salvage Therapy After Radiation Failure — Covered Under Strict Conditions
This is where the real complexity lives. CMS covers cryosurgery of the prostate as salvage therapy, but only under a narrow set of conditions. The patient must have:
| # | Covered Indication |
|---|---|
| 1 | Failed a trial of radiation therapy as their primary treatment, AND |
| 2 | Met one of the following: Stage T2B or below, Gleason score below 9, OR PSA below 8 ng/mL |
The clinical logic here matters for your documentation strategy. CMS is essentially saying that salvage CSAP is only appropriate for patients with lower-risk disease characteristics at the time of recurrence. A patient with a Gleason score of 9 or higher, or a PSA of 8 ng/mL or above, who also has disease beyond Stage T2B is not covered. Any one of those conditions being met is sufficient for coverage—but the radiation failure requirement is non-negotiable.
Before any salvage CSAP claim goes out the door, your billing team needs documented evidence of prior radiation therapy and documented evidence that the patient meets at least one of the three clinical thresholds. This isn't optional documentation—it's the medical necessity standard CMS has set.
This policy covers services across inpatient hospital, outpatient hospital incident to a physician's service, and physicians' services benefit categories. If your facility bills under any of those categories, NCD 123 Medicare applies to your claims.
There is no explicit prior authorization requirement listed in this NCD, but that doesn't mean your MAC isn't imposing one at the local level. Check your Medicare Administrative Contractor's local coverage determination for any prior auth requirements layered on top of this national policy. What CMS sets nationally is a floor—your MAC can add requirements.
CMS Cryosurgery of Prostate Exclusions and Non-Covered Indications
CMS draws a hard line on what salvage therapy it will cover. The policy is explicit: cryosurgery as salvage therapy is not covered after the failure of any primary treatment other than radiation therapy.
If your patient had primary hormone therapy, chemotherapy, or surgery as their first-line treatment and then failed, salvage CSAP is not covered under Medicare. Full stop. This is one of those policy restrictions that sounds obvious once you read it, but in practice, billing teams see claims submitted for salvage CSAP without confirming what the primary treatment actually was.
There is also a historical coverage restriction worth knowing. Salvage cryosurgery services performed prior to June 30, 2001, are not covered. This is unlikely to affect current claims, but it matters if you're dealing with any retroactive billing situations or audits touching older dates of service.
The bottom line is this: CMS salvage cryosurgery coverage is radiation-specific. Any other failed primary treatment means the salvage CSAP claim won't survive scrutiny under this coverage policy.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Primary treatment for clinically localized prostate cancer, Stages T1–T3 | Covered | Policy lists no specific codes — verify with MAC | Document tumor stage clearly in the record |
| Salvage therapy after radiation failure, Stage T2B or below | Covered | Policy lists no specific codes — verify with MAC | Must also confirm radiation therapy was primary treatment |
| Salvage therapy after radiation failure, Gleason score below 9 | Covered | Policy lists no specific codes — verify with MAC | One condition is sufficient; document the specific qualifying criterion |
| Salvage therapy after radiation failure, PSA below 8 ng/mL | Covered | Policy lists no specific codes — verify with MAC | PSA value must be documented in the medical record at time of treatment decision |
| Salvage therapy after failure of non-radiation primary treatment | Not Covered | N/A | Hormone therapy, chemotherapy, or surgery as prior primary treatment does not qualify |
| Salvage therapy for services prior to June 30, 2001 | Not Covered | N/A | Historical restriction; relevant for audits only |
| Salvage therapy with Stage above T2B, Gleason 9 or higher, AND PSA 8 ng/mL or above | Not Covered | N/A | Patient must meet at least one of the three criteria; failing all three means no coverage |
CMS Cryosurgery of the Prostate Billing Guidelines and Action Items 2026
The modified coverage policy is effective March 7, 2026. Here's what your billing team needs to do before and after that date.
| # | Action Item |
|---|---|
| 1 | Audit your pre-authorization and documentation workflows before March 7, 2026. Pull a sample of recent CSAP claims and confirm each one has documented tumor stage, prior treatment history, and—for salvage cases—the specific clinical threshold met (stage, Gleason score, or PSA). If your documentation doesn't support the claim, your exposure is real. |
| 2 | Verify applicable procedure codes with your MAC now. This policy lists no specific CPT or HCPCS codes. That's not unusual for an NCD, but it means your cryosurgery of the prostate billing relies on codes your MAC has designated under this policy. Contact your Medicare Administrative Contractor directly, or check their local coverage determination for the procedure codes they expect on claims under NCD 123. |
| 3 | Build a salvage therapy documentation checklist. Every salvage CSAP claim needs three things: proof of prior radiation therapy as primary treatment, the patient's staging at time of recurrence, and at least one of the three qualifying criteria documented. Build this into your pre-claim review process, not your post-denial workflow. |
| 4 | Train your coding team on the primary-versus-salvage distinction. The biggest claim denial risk under this policy isn't missing a code—it's misclassifying the clinical context. A coder or biller who doesn't know the difference between primary CSAP and salvage CSAP will submit claims that don't survive a pre-payment review. Run a focused training session before the effective date of March 7, 2026. |
| 5 | Review your outpatient hospital charge capture separately. This NCD applies to outpatient hospital incident-to billing, not just physician professional claims. If your facility bills for CSAP on the facility side, make sure your charge description master and clinical documentation standards align with what NCD 123 requires. Facility-side denials and professional-side denials on the same case compound your reimbursement loss. |
| 6 | Check for MAC-level prior authorization requirements. This NCD doesn't mandate prior auth, but your MAC may. A claim that meets NCD 123 criteria but lacks a required prior auth from your local contractor still denies. Look this up before March 7, 2026, not after your first denial. |
If your practice treats a high volume of prostate cancer patients across multiple payers, talk to your compliance officer about how this modified policy interacts with your commercial payer contracts. Some commercial policies mirror CMS coverage criteria—others don't. Don't assume alignment.
| Previous Version | Current Version |
|---|---|
| Coverage is considered experimental and investigational for all indications | Coverage is considered medically necessary when specific criteria are met |
| Prior authorization is not required | Prior authorization is required for initial treatment |
| Documentation must include clinical history | Documentation must include clinical history |
| Re-review every 24 months | Re-review every 12 months with updated clinical documentation |
CPT, HCPCS, and ICD-10 Codes for Cryosurgery of the Prostate Under NCD 123
A Note on Code Availability
This policy does not list specific CPT, HCPCS Level II, or ICD-10-CM codes in the policy data. This is common with NCDs—CMS sets the coverage standard nationally, and procedure codes are typically mapped at the MAC level or through the Medicare Claims Processing Manual transmittals referenced in the policy.
For cryosurgery of the prostate billing, your team needs to confirm applicable codes through:
- Your Medicare Administrative Contractor directly
- The claims processing transmittals CMS references in NCD 123: TN 774 (Medicare Hospital Manual), TN 1835 (Medicare Intermediary Manual), TN 1710 (Medicare Carriers Manual), and TN 260 (Medicare Claims Processing Manual)
- Your internal CDM and charge capture system, cross-referenced against MAC guidance
Do not bill placeholder codes or assume codes from prior claim history without confirming they're still valid under the current policy version. Code-to-policy mapping can shift when a policy is modified, and a mismatch is a fast path to a claim denial and a potential compliance issue.
If you're unsure how to map your current procedure codes to NCD 123 after the March 7, 2026 effective date, involve your compliance officer or billing consultant before submitting claims.
