CMS Retired NCD 273 for TENS — What Billing Teams Need to Know in 2026
TL;DR: The Centers for Medicare & Medicaid Services modified NCD 273, the TENS coverage policy, effective January 9, 2026. The section has been formally retired and consolidated into NCD 160.27. Here's what changes for billing teams.
CMS TENS coverage policy has officially moved. NCD 273 — which governed Transcutaneous Electrical Nerve Stimulator coverage under the NCD Manual — no longer exists as a standalone policy. The Centers for Medicare & Medicaid Services retired this section and folded it into NCD 160.27 back in 2012, but the January 9, 2026 update formalizes that removal. If your billing team is still citing NCD 273 in medical necessity documentation or prior authorization requests, stop. You're citing a dead policy, and that's a fast path to a claim denial.
This policy falls under the durable medical equipment benefit category. No specific CPT or HCPCS codes are listed in the current NCD 273 policy data — you'll find the operative coding guidance under NCD 160.27 and its cross-referenced sections.

CMS TENS Coverage Criteria and Medical Necessity Requirements 2026
Whether TENS is covered under Medicare has not changed in substance — but where you find those rules has changed. NCD 160.27 now holds all TENS coverage criteria. That's been true since June 8, 2012, but NCD 273 stayed in the manual as a pointer. The January 9, 2026 update removes even that pointer.
If your team is pulling coverage policy documentation for TENS claims, NCD 273 is no longer a valid source. Medical necessity arguments grounded in NCD 273 language will not hold up in an audit or appeal. Use NCD 160.27 directly.
Two additional cross-references matter here. NCD 160.13 governs supplies used in delivering TENS and Neuromuscular Electrical Stimulation (NMES). NCD 10.2 covers TENS specifically for acute post-operative pain. If your billing mix includes post-surgical TENS, that's a separate policy with its own medical necessity criteria — don't assume NCD 160.27 covers everything.
Prior authorization requirements for TENS under Medicare flow through your Medicare Administrative Contractor. MAC-level local coverage determinations often layer on top of NCD-level coverage policy, so check your MAC's LCD for TENS as well. What your MAC says about prior authorization may be more restrictive than the NCD itself.
Coverage Indications at a Glance
This table reflects what NCD 273 currently contains. The substantive coverage criteria now live in NCD 160.27.
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| TENS for pain management (general) | Consolidated into NCD 160.27 | See NCD 160.27 | NCD 273 retired June 8, 2012; formally removed January 9, 2026 |
| Supplies used in TENS/NMES delivery | See NCD 160.13 | See NCD 160.13 | Cross-referenced separately |
| TENS for acute post-operative pain | See NCD 10.2 | See NCD 10.2 | Governed by separate NCD |
CMS TENS Billing Guidelines and Action Items 2026
The retirement of NCD 273 is administrative, but the billing implications are real. Here's what to do before your next TENS claim goes out.
| # | Action Item |
|---|---|
| 1 | Remove NCD 273 from all internal coverage templates. If your charge capture tools, ABN templates, or denial management workflows reference NCD 273, update them now. The effective date of this change is January 9, 2026 — that's already passed. |
| 2 | Update your prior authorization reference documents to cite NCD 160.27. Any prior auth request for TENS that cites NCD 273 as the governing coverage policy is citing a retired document. Payers and MACs expect you to cite the current, active policy. |
| 3 | Pull NCD 160.27 and confirm your team has read it. This is where TENS coverage criteria, medical necessity standards, and reimbursement guidance now live. If your billing team hasn't reviewed NCD 160.27 recently, do it now. The substantive rules haven't changed, but you need to be working from the right document. |
| 4 | Check NCD 10.2 if you bill TENS for post-operative pain. This is a separate coverage policy with its own criteria. Post-op TENS billing does not fall under NCD 160.27. If your billing guidelines conflate the two, separate them. |
| 5 | Review NCD 160.13 for TENS supply billing. TENS supply codes fall under NCD 160.13, not NCD 160.27. If your DME suppliers bill for electrodes, leads, or related supplies, confirm they're referencing the correct policy on those claims. |
| 6 | Check your MAC's local coverage determination for TENS. The NCD sets the floor. Your Medicare Administrative Contractor may have a more specific LCD that governs medical necessity, documentation requirements, and prior authorization thresholds. NCD changes don't automatically update MAC-level rules. |
| 7 | Audit recent TENS claims for citation errors. Pull claims filed in the last 90 days that referenced NCD 273. If any went out with that citation in supporting documentation, flag them for review. A claim denial based on policy citation errors is avoidable, and it's easier to fix proactively than through appeal. |
If you're unsure how this consolidation affects your documentation practices or if your organization has a high volume of TENS claims, talk to your compliance officer before your next billing cycle closes.
| Previous Version | Current Version |
|---|---|

CPT, HCPCS, and ICD-10 Codes for TENS Under NCD 273
Codes Listed in NCD 273 Policy Data
The current NCD 273 policy data does not list specific CPT or HCPCS codes. This is consistent with its retired status — the operative codes for TENS billing are now found in the cross-referenced NCDs.
| Code | Source | Where to Find Coverage Criteria |
|---|---|---|
| TENS device codes | NCD 160.27 | NCD 160.27 — TENS Coverage |
| TENS/NMES supply codes | NCD 160.13 | NCD 160.13 — Supplies for TENS and NMES |
| Acute post-operative TENS codes | NCD 10.2 | NCD 10.2 — TENS for Acute Post-Operative Pain |
Do not use NCD 273 as a code source. It has no active code mappings.
What the NCD 273 Retirement Actually Means for DME Billing
Here's the honest take: this change is mostly housekeeping. CMS retired the substantive content of NCD 273 in 2012. The January 9, 2026 update just removes the last remnant from the NCD Manual.
But housekeeping changes cause real claim denial problems when billing teams don't track them. A prior authorization request that cites a retired NCD signals to a reviewer that your documentation process is out of date. That's not the impression you want to make when you're fighting for reimbursement on a durable medical equipment claim.
The real issue here is that TENS billing now has three separate governing NCDs — 160.27 for general coverage, 160.13 for supplies, and 10.2 for post-op pain. That's three policies your billing team needs to know, not one. Make sure your billing guidelines reflect that structure clearly.
