TL;DR: The Centers for Medicare & Medicaid Services modified NCD 144 governing granulocyte transfusion coverage, with an effective date of March 7, 2026. Here's what billing teams need to know.
CMS granulocyte transfusion coverage policy under NCD 144 in the Medicare system covers this service for patients with severe infection and granulocytopenia — but only under two tightly defined clinical indications. This policy applies across inpatient hospital, outpatient hospital (incident to a physician's service), and physicians' services benefit categories. No specific CPT or HCPCS codes are listed in the NCD 144 policy document itself, which creates real upstream work for your coding team.

CMS Granulocyte Transfusion Coverage Criteria and Medical Necessity Requirements 2026
NCD 144 is the National Coverage Determination governing Medicare coverage of granulocyte transfusions. The Centers for Medicare & Medicaid Services covers this service for patients suffering from both severe infection and granulocytopenia simultaneously. One condition without the other does not meet the medical necessity threshold this policy sets.
Granulocytopenia is defined in the policy as fewer than 500 granulocytes per mm³ of whole blood. That's the lab threshold your documentation needs to show. If the patient's count is above 500, you don't have a covered claim — regardless of how sick the patient is.
There are exactly two covered indications under this coverage policy:
| # | Covered Indication |
|---|---|
| 1 | Granulocytopenia with evidence of gram negative sepsis. The patient must have documented granulocytopenia (fewer than 500 granulocytes/mm³) and clinical or laboratory evidence of gram negative sepsis. |
| 2 | Granulocytopenia in febrile patients with local progressive infections unresponsive to appropriate antibiotic therapy, thought to be due to gram negative organisms. This is a narrower pathway. The infection must be progressing despite appropriate antibiotic treatment, and the clinical picture must point to gram negative organisms. |
Both indications require granulocytopenia to be present. Neither indication covers granulocyte transfusion as a prophylactic measure or as treatment for infections clearly caused by gram positive organisms.
The policy does not mention prior authorization requirements explicitly. That said, your Medicare Administrative Contractor may impose prior auth or prior authorization requirements at the local level. Check with your MAC before assuming federal silence means local clearance.
This is a service where reimbursement hinges almost entirely on documentation quality. The two covered indications are specific. Your attending physician's notes need to reflect the gram negative clinical picture, the granulocyte count, and — for the second indication — the failure of antibiotic therapy.
CMS Granulocyte Transfusion Exclusions and Non-Covered Indications
The policy does not list explicit exclusion categories by name. But the structure of NCD 144 creates clear non-coverage zones by implication.
Granulocyte transfusions are not covered under Medicare when granulocytopenia is absent. A patient with gram negative sepsis who has a normal or elevated granulocyte count falls outside the covered indications — full stop.
Gram positive infections are not covered indications. The policy specifically references gram negative organisms in both covered indications. If your clinical documentation points to gram positive organisms, you do not have a covered claim under NCD 144.
Prophylactic granulocyte transfusions are not covered. The policy is written around active, severe infection. There is no coverage pathway for transfusions given in anticipation of infection or as preventive treatment during chemotherapy-induced neutropenia — unless the patient already meets one of the two active-infection criteria.
This matters for oncology billing teams in particular. Neutropenic patients getting chemotherapy are a common population where granulocyte transfusion might come up clinically. Unless that patient also has active gram negative sepsis or a progressive local infection unresponsive to antibiotics, you do not have NCD 144 coverage.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Granulocytopenia (<500/mm³) with evidence of gram negative sepsis | Covered | Not specified in NCD 144 | Lab documentation of granulocyte count required; gram negative sepsis must be evidenced in clinical record |
| Granulocytopenia in febrile patients with local progressive infections unresponsive to antibiotics, thought to be gram negative | Covered | Not specified in NCD 144 | Must document antibiotic failure and gram negative clinical suspicion |
| Granulocytopenia without active infection | Not Covered | — | Granulocytopenia alone does not meet medical necessity |
| Gram positive infections with granulocytopenia | Not Covered | — | Both covered indications specify gram negative organisms |
| Prophylactic granulocyte transfusions | Not Covered | — | No coverage pathway for preventive use under NCD 144 |
| Normal/elevated granulocyte count with severe infection | Not Covered | — | Granulocytopenia is a required element for both covered indications |
CMS Granulocyte Transfusion Billing Guidelines and Action Items 2026
The absence of specific CPT or HCPCS codes in the NCD 144 document is the first problem your billing team needs to solve. Here's what to do before and after the March 7, 2026 effective date.
| # | Action Item |
|---|---|
| 1 | Identify the correct billing codes with your MAC before March 7, 2026. NCD 144 does not list CPT or HCPCS codes. Contact your Medicare Administrative Contractor directly to confirm which codes they expect on claims for granulocyte transfusion services. This is not optional — submitting without confirming the right codes is a direct path to claim denial. |
| 2 | Build documentation checklists for both covered indications. Your clinical staff and coders need a shared checklist. For indication one: granulocyte count below 500/mm³, evidence of gram negative sepsis. For indication two: granulocyte count below 500/mm³, fever, documented antibiotic failure, gram negative clinical suspicion. Any claim that can't check every box on the relevant list is a denial waiting to happen. |
| 3 | Audit recent claims for documentation completeness. Pull claims for granulocyte transfusion services from the past 12 months. Check whether each claim's supporting documentation would pass the NCD 144 criteria as modified. If you find gaps, address them through your internal correction process before the effective date. |
| 4 | Review your charge capture workflow to confirm the correct benefit category is applied. NCD 144 covers granulocyte transfusion billing under inpatient hospital services, outpatient hospital services incident to a physician's service, and physicians' services. Make sure your charge capture team knows which benefit category applies in each setting — inpatient versus outpatient facility versus professional claim. |
| 5 | Alert your hematology, oncology, and infectious disease teams about the gram negative specificity. Clinicians need to know that documentation must explicitly address gram negative organisms. A chart that says "bacterial infection" without specifying organism type will create coverage ambiguity. The word "gram negative" — or the lab evidence supporting it — needs to appear in the record. |
| 6 | Check for MAC-level local coverage determinations that may layer additional requirements. NCD 144 is a national policy, but your MAC may have issued an LCD that adds documentation requirements, coverage restrictions, or code-level guidance specific to your region. Search your MAC's website for any LCD or billing guidelines tied to granulocyte transfusions before the March 7, 2026 effective date. |
| 7 | If your practice sees high volumes of chemotherapy-related neutropenia, flag this policy for your compliance officer. The non-coverage of prophylactic transfusions creates real risk in oncology settings. If you're not sure how NCD 144 applies to your patient mix, talk to your compliance officer before the effective date. |

CPT, HCPCS, and ICD-10 Codes for Granulocyte Transfusions Under NCD 144
Covered CPT/HCPCS Codes (When Medical Necessity Criteria Are Met)
The NCD 144 policy document does not list specific CPT or HCPCS codes. This is a significant gap for billing teams, and it's not unusual for older NCDs to predate the current code set.
Your coding team should work with your MAC to confirm the correct codes. Granulocyte transfusion services are typically captured through transfusion medicine codes, but code selection depends on the specific service components billed (collection, processing, administration) and the care setting.
Do not guess on codes here. A granulocyte transfusion claim is already a high-documentation-burden claim. Submitting on the wrong code compounds your denial risk.
Key ICD-10-CM Diagnosis Codes
NCD 144 does not list specific ICD-10-CM codes. Based on the covered indications, the relevant diagnosis landscape includes agranulocytosis and gram negative sepsis codes — but confirm the specific codes with your MAC and your coding team against the current ICD-10-CM code set. Do not rely on inferred codes for claims submission.
