TL;DR: The Centers for Medicare & Medicaid Services modified NCD 313 governing lumbar artificial disc replacement (LADR) coverage, with a policy update effective January 9, 2026. The age-based non-coverage rule remains in place — LADR is non-covered for Medicare beneficiaries over 60 — and MAC-level discretion still applies for patients 60 and younger.
CMS updated its lumbar artificial disc replacement coverage policy under NCD 313 in the Medicare system, with an effective date of January 9, 2026. The policy does not list specific CPT or HCPCS codes, but it governs every LADR claim submitted to Medicare — making it directly relevant to spine surgery billing teams, hospital outpatient billing departments, and orthopedic and neurosurgery practices. If your team bills for LADR procedures, this is the policy that controls whether Medicare pays or denies.

CMS Lumbar Artificial Disc Replacement Coverage Criteria and Medical Necessity Requirements 2026
The CMS lumbar artificial disc replacement coverage policy under NCD 313 draws a hard line based on patient age. Medicare will not cover LADR for any beneficiary over 60 years of age. That's the rule — no exceptions, no prior authorization pathway that unlocks coverage for older patients.
For beneficiaries 60 and younger, CMS has not made a national coverage determination. Coverage decisions for that group fall to your regional Medicare Administrative Contractor (MAC). That means your MAC's local coverage determination (LCD) controls reimbursement for younger patients — and those LCDs vary by region.
What LADR Is (Clinically, for Medical Necessity Purposes)
LADR is a surgical procedure on the lumbar spine. It involves complete removal of a damaged or diseased lumbar intervertebral disc and implantation of an artificial disc. The FDA has approved LADR for spine arthroplasty in skeletally mature patients with degenerative or discogenic disc disease at one level, from L3 to S1.
The procedure serves as an alternative to lumbar spinal fusion. It targets pain reduction, movement restoration at the surgical site, and restoration of intervertebral disc height.
Medical Necessity Under NCD 313
CMS has determined that LADR does not meet the "reasonable and necessary" standard for Medicare beneficiaries over 60. That finding has been in place since August 14, 2007, and this 2026 modification to NCD 313 does not reverse it.
The medical necessity question for patients 60 and younger sits with the MAC. Before submitting a claim for a younger beneficiary, pull your MAC's applicable LCD and confirm what documentation they require. Prior authorization requirements vary by MAC — check your contractor's guidance directly, because a claim denial based on missing documentation is avoidable.
CMS LADR Exclusions and Non-Covered Indications
The non-coverage rule under NCD 313 has two distinct periods. Understanding both matters if you're handling any late claims, audits, or appeals.
Period 1: May 16, 2006 through August 13, 2007
During this window, CMS specifically found that LADR using the Charite™ lumbar artificial disc was non-covered for Medicare beneficiaries over 60. For other devices used during this period under an investigational device exemption (IDE) in eligible clinical trials, Medicare coverage was not affected by the NCD — those IDE claims had their own pathway.
Period 2: August 14, 2007 onward (including January 9, 2026 effective date)
Starting August 14, 2007, CMS expanded the non-coverage finding to all LADR procedures — not just the Charite™ device — for beneficiaries over 60. This is the operative rule today. The January 9, 2026 NCD 313 update maintains this framework.
The real issue here is the age cutoff. Sixty is a hard threshold, not a soft guideline. Medicare denies LADR for any beneficiary who exceeds it, regardless of clinical justification, implant type, or number of levels treated.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| LADR — Medicare beneficiary over age 60 (on or after August 14, 2007) | Not Covered | No specific codes listed in NCD 313 | Non-covered per CMS "reasonable and necessary" finding; claim denial expected |
| LADR with Charite™ disc — Medicare beneficiary over age 60 (May 16, 2006–August 13, 2007) | Not Covered | No specific codes listed in NCD 313 | Historical non-coverage; relevant for audits or late appeals only |
| LADR with non-Charite™ disc under IDE in eligible clinical trials (May 16, 2006–August 13, 2007) | Coverage Not Impacted | No specific codes listed in NCD 313 | IDE coverage pathway applied; NCD did not restrict this group |
| LADR — Medicare beneficiary age 60 or younger | No National Determination (MAC Discretion) | No specific codes listed in NCD 313 | Contact your Medicare Administrative Contractor for applicable LCD and documentation requirements |
CMS Lumbar Artificial Disc Replacement Billing Guidelines and Action Items 2026
This is where the policy gets practical. The NCD 313 framework is not complicated — but the age verification step is where claims fall apart. Here's what your billing team should do now.
| # | Action Item |
|---|---|
| 1 | Build an age-check into your LADR claim workflow before January 9, 2026. Every LADR claim for a Medicare patient should trigger an automatic age verification. If the patient is over 60, the claim should not go out — it will be denied. This is not a borderline case; CMS has held this position since 2007. |
| 2 | Pull your MAC's LCD for LADR before billing any patient age 60 or younger. NCD 313 leaves these patients to MAC discretion. Your MAC may have specific medical necessity criteria, documentation requirements, or prior authorization requirements that differ from neighboring regions. Don't assume national rules apply here — they don't. |
| 3 | Confirm with your MAC whether prior authorization is required for LADR in your region. This step belongs in your pre-authorization checklist for any spine surgery case involving a Medicare patient 60 or younger. A missing prior auth is a predictable claim denial — and it's preventable. |
| 4 | Audit any pending LADR claims with dates of service on or after January 9, 2026. Review each one for patient age. If you have claims in queue for beneficiaries over 60, pull them and discuss with your compliance officer before submission. |
| 5 | If you handle audits, appeals, or late claims from the 2006–2007 period, understand the two-phase rule. The Charite™-specific non-coverage applied May 16, 2006 through August 13, 2007. The broader all-device non-coverage began August 14, 2007. Device type matters for that first window — it doesn't matter after August 13, 2007. |
| 6 | Document clinical indications clearly for every LADR case. Even if a patient is age 60 or younger and your MAC covers the procedure, your documentation needs to support the FDA-approved indication: skeletally mature patient, degenerative or discogenic disc disease, one level, L3 to S1. Gaps in that documentation are gaps in your medical necessity defense. |
| 7 | Loop in your compliance officer if your practice is seeing LADR volume with Medicare patients near the age threshold. The age cutoff at 60 is precise, and the financial exposure from a pattern of denied claims is real. If you're not certain how this applies to your patient mix, get a second set of eyes before the effective date passes. |
| Previous Version | Current Version |

CPT, HCPCS, and ICD-10 Codes for Lumbar Artificial Disc Replacement Under NCD 313
NCD 313 does not list specific CPT, HCPCS, or ICD-10 codes. The Centers for Medicare & Medicaid Services did not include procedure codes in the policy document.
This is worth calling out directly: the absence of specific codes in the NCD does not mean LADR billing is unregulated. It means you need to identify the correct procedure codes through your MAC's LCD and current coding resources — CPT code books, CMS claims processing transmittals, and your MAC's billing guidelines for spine arthroplasty.
For reference, CMS claims processing instructions for NCD 313 are published in Transmittal 1340 (Medicare Claims Processing). Your coding team should cross-reference that transmittal when building or updating your charge capture for LADR.
If your MAC has published an LCD covering LADR for younger beneficiaries, that LCD will typically include the applicable CPT and ICD-10 codes. Pull the LCD from your MAC's website and align your charge capture accordingly.
What to Ask Your MAC
- Which CPT codes does the MAC recognize for LADR billing under the applicable LCD?
- Are there covered ICD-10-CM diagnosis codes required for medical necessity documentation?
- Does the MAC require prior authorization for LADR, and if so, what is the process?
- Are there frequency limitations or coverage criteria beyond what NCD 313 specifies?
These questions belong in a direct conversation with your MAC's provider relations team — not in an assumption built into your billing workflow.
