TL;DR: The Centers for Medicare & Medicaid Services (CMS) modified NCD 194, the National Coverage Determination governing dental examination prior to kidney transplantation, effective March 7, 2026. Here's what billing teams need to do.
This policy clarifies an important exception to Medicare's standard dental services exclusion under §1862(a)(12) of the Act. The policy does not list specific CPT or HCPCS codes, but the billing implications split across Part A and Part B depending on who performs the examination — and getting that distinction wrong will cost you. If your facility handles renal transplant workups, read this before March 7, 2026.

CMS Dental Examination Prior to Kidney Transplantation Coverage Criteria and Medical Necessity Requirements 2026
The core coverage policy here is narrow but meaningful. Medicare ordinarily excludes dental services under §1862(a)(12) of the Act — that exclusion is broad and it catches a lot of legitimate clinical work. NCD 194 carves out one specific situation: an oral or dental examination performed on an inpatient basis as part of a comprehensive pre-operative workup prior to renal transplant surgery.
The medical necessity rationale is explicit in the policy language. The examination is not covered because it treats teeth or supporting structures. It's covered because it identifies existing medical problems — specifically, sources of potential infection — that could reduce the likelihood of successful transplant surgery or expose the patient to additional surgical risk. That distinction is the entire legal basis for the coverage, and it needs to be reflected in your documentation.
Prior authorization requirements are not specified in this policy, but the inpatient setting and transplant surgery context create their own utilization management pressures. Make sure your clinical documentation clearly connects the oral examination to the transplant workup — not to dental treatment. A claim denial based on the dental exclusion is entirely avoidable here, but only if the medical record supports the pre-surgical purpose.
The coverage policy also does not extend to outpatient settings. The examination must occur on an inpatient basis. Perform this exam in an outpatient dental clinic, even the day before admission, and you've likely lost the coverage argument. Bill it as part of the inpatient stay or don't bill it under this exception.
CMS Dental Examination Prior to Kidney Transplantation Exclusions and Non-Covered Indications
The dental services exclusion under §1862(a)(12) still applies to everything that isn't a pre-surgical oral examination in this specific transplant workup context. Routine dental care, periodontal treatment, tooth extractions, and restorations remain non-covered under Medicare — NCD 194 does not change that.
The policy also does not extend to other transplant types. The coverage language is specific to renal (kidney) transplant surgery. If your team is billing for oral examinations prior to liver, heart, or lung transplants, this NCD does not provide coverage authority for those cases. Those may be supported under other clinical rationale, but not under NCD 194.
A dentist performing the examination is not recognized as a physician under §1861(r) of the Act. That's a hard rule with direct billing consequences — it determines whether the claim routes through Part A or Part B. It is not a gray area.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Oral/dental examination performed inpatient as part of pre-renal transplant workup — performed by a hospital-staff dentist | Covered (Part A) | No specific codes listed in NCD 194 | Dentist must be on hospital staff; dentist not recognized as physician under §1861(r) |
| Oral/dental examination performed inpatient as part of pre-renal transplant workup — performed by a physician | Covered (Part B) | No specific codes listed in NCD 194 | Physician performing the exam bills under Part B |
| Routine dental care (any setting) | Not Covered | N/A | Excluded under §1862(a)(12); NCD 194 does not apply |
| Oral examination in outpatient setting prior to renal transplant | Not Covered | N/A | Coverage requires inpatient basis |
| Oral examination prior to non-renal transplant (liver, heart, lung, etc.) | Not Covered under NCD 194 | N/A | NCD 194 is specific to renal transplant surgery |
CMS Dental Examination Prior to Kidney Transplantation Billing Guidelines and Action Items 2026
The Part A vs. Part B split is the operational crux of this policy. Get it right before the March 7, 2026 effective date.
| # | Action Item |
|---|---|
| 1 | Confirm who is performing the exam before the claim is coded. If a dentist on the hospital's staff performs the oral examination, that claim routes through Part A. If a physician performs it, it routes through Part B. The same examination, billed to the wrong part, will deny. Build this determination into your pre-claim workflow for all renal transplant cases. |
| 2 | Update your clinical documentation templates for transplant workup cases. The medical record needs to establish — explicitly — that the purpose of the dental or oral examination is pre-surgical infection risk identification, not dental treatment. Work with your transplant surgery and documentation improvement teams to make this language standard in the admission workup notes before March 7, 2026. |
| 3 | Audit your recent claim denials for dental exclusion codes on transplant cases. If your billing team has been writing off oral exam charges on renal transplant inpatients because of the dental services exclusion, NCD 194 gives you coverage authority. Pull 12–24 months of denials and identify cases where this exception should have applied. Reimbursement recovery is on the table. |
| 4 | Do not bill this exception for outpatient encounters. The inpatient requirement is not negotiable under this policy. If the oral examination was performed during a pre-admission clinic visit rather than during the inpatient stay, NCD 194 does not cover it. Review your scheduling and admission workflows to ensure the examination occurs after formal inpatient admission. |
| 5 | Communicate the Part A vs. Part B distinction to your transplant surgery billing team and your hospital's dental staff. This is not intuitive to clinicians, and dentists in particular are accustomed to being outside the Medicare billing structure entirely. A brief internal memo before March 7, 2026 prevents the "we didn't know" denials that show up six months later. |
| 6 | If your facility's transplant volume is high or your revenue cycle team is uncertain about how to document and code these claims, loop in your compliance officer before the effective date. The intersection of the dental exclusion, Part A/Part B routing, and the physician-recognition rules under §1861(r) is not a place to wing it. |

CPT, HCPCS, and ICD-10 Codes for Dental Examination Prior to Kidney Transplantation Under NCD 194
NCD 194 does not list specific CPT, HCPCS, or ICD-10 codes. This is one of the more frustrating aspects of this coverage policy for billing teams — the clinical indication is clear, the coverage rationale is explicit, but CMS has not enumerated the procedure codes that apply.
What This Means for Your Charge Capture
Without enumerated codes, your billing team needs to identify the appropriate procedure codes based on the type of examination performed and who performs it. Common dental and oral examination codes used in hospital-based settings may apply, but your coding team and compliance officer should confirm code selection against the clinical documentation before submitting claims under this NCD.
No Specific Codes Listed in Policy Data
| Code Type | Status |
|---|---|
| CPT Codes | None listed in NCD 194 |
| HCPCS Codes | None listed in NCD 194 |
| ICD-10-CM Codes | None listed in NCD 194 |
The absence of codes in the policy does not mean the service is unbillable — it means your coding team carries more responsibility for selecting the appropriate codes based on clinical documentation. This is a situation where your certified coders and compliance officer should be aligned before you set your charge capture rules. Do not default to a generic dental exam code without confirming it's appropriate for inpatient hospital-based billing.
