Summary: The Centers for Medicare & Medicaid Services modified its coverage policy for Thermal Intradiscal Procedures (TIPs), effective May 15, 2026. Here's what billing teams need to do.
CMS's thermal intradiscal procedures coverage policy governs whether Medicare reimburses procedures like intradiscal electrothermal therapy (IDET) and related interventions for chronic discogenic back pain. The effective date of May 15, 2026 makes this a near-term priority for any practice billing spinal pain management services. This policy does not list specific CPT codes in the available data — but that doesn't mean you sit this one out. The clinical scope is narrow and the denial risk is high.

CMS Thermal Intradiscal Procedures Coverage Criteria and Medical Necessity Requirements 2026
CMS has long treated thermal intradiscal procedures as a category with serious evidentiary problems. The core issue is medical necessity — CMS has not been convinced that TIPs, including intradiscal electrothermal therapy and related techniques, produce clinically meaningful outcomes for most Medicare beneficiaries with discogenic low back pain.
If your practice bills for these procedures, you already know the scrutiny is intense. CMS's position reflects a broader pattern: when randomized controlled trial data is mixed or weak, CMS moves toward non-coverage or tightly restricted coverage. TIPs fall squarely into that bucket.
Whether Medicare covers thermal intradiscal procedures under this modified policy depends on how your Medicare Administrative Contractor interprets the updated CMS guidance. Some MACs have issued local coverage determinations that are more permissive than national CMS positions — and some are more restrictive. Know which MAC jurisdiction you're billing into before May 15, 2026.
Medical necessity documentation is your first line of defense against a claim denial. That means conservative treatment failure is documented explicitly — duration, modalities tried, and outcomes recorded in the chart. Vague references to "failed conservative care" won't survive a post-payment audit.
Prior authorization is not universally required for TIPs under Medicare, but that doesn't protect you from prepayment review or retrospective denial. CMS and its MACs have tools that flag high-utilization procedure codes, and TIPs have historically drawn that kind of scrutiny.
CMS Thermal Intradiscal Procedures Exclusions and Non-Covered Indications
This is where thermal intradiscal procedures billing gets painful. CMS has historically classified most TIP variants as not medically necessary or investigational for the Medicare population. The clinical rationale: systematic reviews show inconsistent evidence for pain relief and functional improvement, and the procedures carry procedural risk without a strong evidence base to justify routine coverage.
Procedures that fall outside a narrowly defined medically necessary indication face automatic non-coverage. That includes TIPs performed for radicular pain rather than isolated discogenic pain, procedures done without documented imaging confirmation of internal disc disruption, and repeat procedures on the same disc level.
If CMS's modified coverage policy moves the bar higher on clinical criteria — which modifications to historically restrictive policies often do — expect stricter documentation thresholds for what qualifies as a covered indication. If you're billing for diagnostic indications that go beyond isolated discogenic pain with a structurally confirmed disc abnormality, those claims are at risk.
Coverage Indications at a Glance
Because the available policy data does not include indication-level detail, the table below reflects CMS's historically documented positions on TIPs based on published policy patterns. Verify current criteria against your MAC's local coverage determination before billing after May 15, 2026.
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Chronic discogenic low back pain with documented disc abnormality | Historically non-covered / investigational | Not specified in available data | CMS and most MACs have not recognized this as a covered indication under Medicare |
| Intradiscal electrothermal therapy (IDET) | Historically not covered | Not specified in available data | Classified as investigational by CMS; confirm MAC LCD status |
| Biacuplasty / radiofrequency annuloplasty | Historically not covered | Not specified in available data | Evidence base insufficient under CMS standards |
| Percutaneous intradiscal radiofrequency thermocoagulation (PIRFT) | Historically not covered | Not specified in available data | Not supported by adequate clinical trial data for Medicare coverage |
| TIPs for radicular pain | Not covered | Not specified in available data | Outside the clinical scope of any historical TIP coverage discussion |
This table reflects historical CMS patterns. The modified policy effective May 15, 2026 may shift one or more of these statuses. Pull the updated policy document directly at app.payerpolicy.org and confirm with your MAC before submitting claims.
CMS Thermal Intradiscal Procedures Billing Guidelines and Action Items 2026
Here's what your billing team should do right now.
| # | Action Item |
|---|---|
| 1 | Pull your MAC's current LCD for thermal intradiscal procedures before May 15, 2026. MACs like Noridian, CGS, Palmetto GBA, and Novitas each maintain their own local coverage determinations for spinal interventions. A CMS-level modification triggers MAC-level review — your MAC may update their LCD in response. Don't assume the national change and the local policy are aligned. |
| 2 | Audit every open or pending TIP claim against the updated criteria. If you have claims in process for procedures performed before May 15, 2026, review them now. Post-modification, CMS auditors will apply the new criteria to claims that land after the effective date — even if the service date predates it in some review contexts. |
| 3 | Update your medical necessity documentation templates immediately. Your charts need to show conservative treatment failure with specifics: duration of treatment (typically six months or more), modalities attempted (physical therapy, medications, injections), and measurable functional outcomes. A chart that says "failed conservative care" without detail won't support reimbursement if the claim goes to review. |
| 4 | Confirm prior authorization requirements with commercial payers who mirror CMS policies. CMS itself doesn't always require prior authorization for TIPs — it often just denies on the back end. But commercial payers frequently align their prior auth rules to CMS coverage positions. If this CMS policy change shifts the coverage stance, your commercial payer prior authorization requirements may follow within one to two contract cycles. |
| 5 | Flag thermal intradiscal procedures billing in your charge capture system for secondary review. Any CPT code associated with TIPs — regardless of what those codes are in the updated policy — should route through a secondary clinical documentation review before the claim drops. This is a high-denial, high-audit category. One clean denial is recoverable. A pattern of denials triggers payer scrutiny across your entire spinal procedure billing. |
| 6 | Talk to your compliance officer before the effective date if your practice has high TIP volume. If thermal intradiscal procedures represent meaningful revenue for your practice, this CMS modification is a financial exposure event. Your compliance officer needs to assess whether your current documentation practices meet the updated criteria and whether any retrospective claim risk exists. Don't wait until you see the first denial. |
| 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 Thermal Intradiscal Procedures Under CMS Policy
The available policy data for this CMS modification does not include specific CPT, HCPCS, or ICD-10 codes. This is not unusual for a CMS-level policy modification — code-level detail often lives in the MAC LCD rather than the national policy document.
What This Means for Your Billing Team
Do not bill thermal intradiscal procedures billing without confirming the applicable codes through your MAC's LCD. CMS national policy sets the coverage framework. Your MAC translates that into specific billable codes, coverage criteria, and documentation requirements.
The procedure codes historically associated with TIPs include annuloplasty and intradiscal intervention codes — but because the policy data does not confirm specific codes, we will not list them here. Publishing unconfirmed codes in a billing context creates real claim denial risk. Verify directly.
Where to Find the Codes
- Your MAC's LCD: Search the CMS LCD database at cms.gov/medicare-coverage-database for "intradiscal" or "thermal" procedures
- The PayerPolicy source document: app.payerpolicy.org/p/cms/324-v1 — this links to the full policy text where code-level detail may be available
- Your billing system's payer policy library: Most major billing platforms pull CMS LCD data; confirm the feed is current as of May 2026
If your practice uses a specialty-specific coding resource for pain management or spine, cross-reference that source against the updated MAC LCD after May 15, 2026. Code lists for interventional spine procedures shift when national coverage policy changes.
