TL;DR: The Centers for Medicare & Medicaid Services modified NCD 93, governing pretransplant blood transfusion coverage for kidney transplant recipients, effective March 7, 2026. Here's what changes for billing teams.
CMS pretransplant transfusion coverage policy under NCD 93 in the Medicare system covers blood transfusions given to kidney transplant recipients before transplant surgery — both nonselective (random) transfusions and donor specific transfusions (DST). The policy does not list specific CPT or HCPCS codes. What it does specify is how the Medicare blood deductible applies — and that distinction has direct consequences for how you handle claims and patient cost-sharing.

CMS Pretransplant Transfusion Coverage Criteria and Medical Necessity Requirements 2026
The core medical necessity standard for this coverage policy is straightforward. Transplant surgeons have established a clear link between pretransplant blood transfusions and improved graft retention outcomes — in both cadaver and living-related kidney transplantation. CMS recognizes this clinical correlation as the basis for coverage.
Medicare covers pretransplant transfusions for kidney transplant recipients with no specific limit on the number of transfusions. That's a meaningful point. There is no ceiling on how many transfusion sessions a patient can receive prior to transplant and still qualify for Medicare reimbursement — as long as those transfusions are medically indicated as part of the pretransplant preparation.
The medical necessity determination rests on the clinical purpose of the transfusion. The blood must be given to the transplant patient as part of pretransplant preparation. Blood given for unrelated acute conditions would follow standard transfusion coverage rules, not this NCD.
Prior authorization is not explicitly required under this coverage policy as written. However, your Medicare Administrative Contractor may have additional local guidance. Check with your MAC before assuming blanket approval — especially for high-volume transfusion protocols.
How the Blood Deductible Applies
This is where NCD 93 gets specific — and where billing errors happen.
Medicare's standard blood deductible applies to pretransplant transfusions. The first three pints of blood per calendar year are subject to the deductible. But the policy draws a sharp line for donor specific transfusions.
When blood is given directly to the transplant patient — as is the case with DST — that blood is treated as "replaced" for purposes of the blood deductible. This means the blood deductible does not reduce the patient's cost-sharing burden for DST the way it would for nonselective transfusions. The deductible replacement rule applies to DST because the blood is being provided by a living related donor specifically for that recipient.
This distinction matters for your billing team. A nonselective (random) transfusion and a DST are both covered. But they are treated differently under the blood deductible provisions. Billing them the same way creates claim denial risk.
Reference the Medicare General Information, Eligibility, and Entitlement Manual, Chapter 3, §20.5.4 for the full blood deductible framework that governs this policy.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Nonselective (random) pretransplant transfusions for kidney transplant recipients | Covered | Not specified in NCD 93 | No limit on number of transfusions; standard Medicare blood deductible applies |
| Donor specific transfusions (DST) — living related donor, given directly to transplant patient | Covered | Not specified in NCD 93 | Blood deductible treated as "replaced" — different cost-sharing treatment than nonselective transfusions |
| Pretransplant transfusions — cadaver transplant recipients | Covered | Not specified in NCD 93 | Same coverage rules apply as living-related; subject to normal blood deductible provisions |
| Pretransplant transfusions — living-related kidney transplantation recipients | Covered | Not specified in NCD 93 | DST deductible replacement rule applies when blood given directly to recipient |
CMS Pretransplant Transfusion Billing Guidelines and Action Items 2026
| # | Action Item |
|---|---|
| 1 | Verify your team knows the DST versus nonselective distinction before March 7, 2026. These two transfusion types carry the same coverage status but different deductible treatment. If your billing staff processes them identically, you will misbill patient cost-sharing for DST cases. |
| 2 | Review how you document DST in the patient record. The blood deductible replacement rule hinges on one fact: the blood was given directly to the transplant patient by a living related donor. Your documentation must support that clearly. Vague documentation creates claim denial exposure when Medicare reviews the file. |
| 3 | Confirm there is no transfusion count ceiling in your internal protocols. NCD 93 explicitly covers pretransplant transfusions without a specific numerical limit. If your billing system flags claims beyond a certain transfusion count for review, that flag may not align with CMS policy. Audit your claim scrubbing rules. |
| 4 | Contact your MAC before the effective date of March 7, 2026 if your program uses high-volume transfusion protocols. The NCD does not impose a limit, but your MAC may have issued a local coverage determination that adds conditions. Billing without checking your MAC's guidance is a gap in your process. |
| 5 | Update patient financial counseling scripts for DST cases. Because the blood deductible is treated as replaced for DST, patients in living-related donor transplant programs have different cost-sharing exposure than patients receiving nonselective transfusions. Your financial counselors need to reflect this in pre-service estimates. |
| 6 | Pull your pretransplant transfusion claims from the last 12 months and verify deductible treatment. If you have been applying the blood deductible to DST claims, you may have over-collected from patients. Identify any corrections needed before the effective date creates a clean baseline going forward. |
| 7 | Loop in your compliance officer if your transplant program bills for both DST and nonselective transfusions. The deductible distinction is not complicated, but the documentation and billing workflow differences between the two transfusion types create audit risk if your team is not aligned. A compliance review before March 7, 2026 is worth the time. |

CPT, HCPCS, and ICD-10 Codes for Pretransplant Transfusions Under NCD 93
Applicable Codes
NCD 93 does not list specific CPT, HCPCS Level II, or ICD-10-CM codes. This is the policy as written and published by CMS. The coverage determination is defined by the clinical context — pretransplant blood transfusion for a kidney transplant recipient — not by a specific code set.
This creates a practical billing challenge. Your team must ensure that whatever transfusion codes you bill (typically from the blood transfusion CPT range) are documented with the pretransplant context clearly established in the medical record. The claim itself won't signal "pretransplant DST" to a payer system unless your coding and documentation make that context explicit.
Work with your coding team to confirm that the procedure codes your facility uses for inpatient blood transfusions are linked to the correct transplant-related diagnosis codes. The lack of a specific code list in NCD 93 is not a blank check — it means the clinical and documentation standards are what protect you from a claim denial.
If you need code-level guidance specific to your facility's charge capture for transplant-related transfusion billing, consult your MAC's billing guidelines or your certified coding team. Do not assume that any transfusion code automatically falls under NCD 93 coverage — the pretransplant indication must be supported by the record.
