Abecma (idecabtagene vicleucel) — HCPCS Q2055

CareCost Estimate · CAR-T Billing Cheat Sheet
Bristol-Myers Squibb (Celgene) / 2seventy bio Autologous anti-BCMA CAR-T (NOT CD19) · Single BCMA-binding domain, 4-1BB costim · Single IV infusion FACT-accredited center only FIRST CAR-T for MM (Mar 26, 2021, KarMMa) Reviewed: May 22, 2026 ASP: Q2 2026
GATE: FACT (or FACT-JACIE) accreditation + ABECMA REMS certification (BMS, separate from Carvykti/Janssen, Kite, AND even Breyanzi/BMS) + indication gate: 2L+ MM = triple-class exposed (IMiD + PI + anti-CD38, KarMMa-3); 4L+ MM = ≥4 prior lines incl. PI + IMiD + anti-CD38 (KarMMa). Missing any = #1 cause of Abecma claim denial.

Codes & NDC

HCPCSQ2055 — "Idecabtagene vicleucel, up to 510M autologous BCMA-directed CAR+ viable T cells, per therapeutic dose"
NDCBMS/Celgene labeler family; patient-specific lot per chain-of-identity label
ICD-10-PCSXW033C3 peripheral / XW043C3 central — drives MS-DRG 018 (inpatient only)
IndicationsR/R MM 2L+ triple-class exposed (KarMMa-3, Apr 4, 2024); R/R MM 4L+ post-PI/IMiD/anti-CD38 (KarMMa, Mar 26, 2021 — FIRST CAR-T for MM)

Encounter spans 6-10 weeks across 3-4 distinct index claims. Vein-to-vein ~4-6 weeks (faster than Carvykti's 5-7 weeks). No extended ≥1-year neuro surveillance tail (that is Carvykti-specific). Document chain of identity (BMS/Celgene labeler) on every claim file.

ABECMA REMS & FACT — required

Closed distribution. All three layers must be in place before any apheresis:

  • Facility on BMS Abecma Treatment Center list (FACT or FACT-JACIE + CRS/ICANS capability + tocilizumab on hand)
  • Prescriber completed ABECMA REMS training + enrolled
  • Pharmacy / cell lab verifies prescriber + facility cert before accepting cellular product
Common error: Carvykti cert does NOT extend to Abecma. BMS administers its own REMS. Breyanzi cert (also BMS) does NOT extend to Abecma either — same hub (BMS Cell Therapy 360), different product certifications. Verify BMS Abecma-specific certification before Stage 1.

BCMA cellular therapy disambiguation

BrandHCPCSClass & positioning
Abecma (ide-cel)Q2055BCMA CAR-T, single binding, 4-1BB; 2L+ MM triple-class exposed; BMS/2seventy — FIRST CAR-T for MM
Carvykti (cilta-cel)Q2056BCMA CAR-T, dual binding, 4-1BB; 2L+ MM lenalidomide-refractory; Janssen labeler 57894
Tecvayli (teclistamab)J9380BCMA x CD3 bispecific Ab; SC dosing; 4L+ MM; Janssen
Elrexfio (elranatamab)J-codeBCMA x CD3 bispecific Ab; SC dosing; 4L+ MM; Pfizer
Abecma was the FIRST CAR-T approved for multiple myeloma. NOT a CD19 CAR-T. Q2055 (BCMA) is NOT interchangeable with Q2041/Q2042/Q2053/Q2054 (CD19 for lymphoma/leukemia). Chain-of-identity label is authoritative for Q2055 vs Q2056.

ICD-10 — myeloma + Abecma-specific

G20.A1/A2 (drug-induced Parkinsonism) is NOT typical for Abecma claims. Those codes are Carvykti-specific (MNT delayed toxicity). If they appear on an Abecma claim, audit for a Q2055/Q2056 mix-up.

Top denials — Abecma-specific

#Reason
1Non-FACT / non-ABECMA-REMS-certified center (Carvykti AND Breyanzi cert do not extend)
22L+: triple-class exposure not documented (#1 KarMMa-3 gate)
34L+: PI / IMiD / anti-CD38 triple-exposure across ≥4 lines not documented
4Wrong Q-code: Q2056 (Carvykti) on Abecma claim
5Wrong Q-code: CD19 CAR-T code (Q2041-Q2054) on Abecma claim
6Outpatient pathway denied (default = inpatient MS-DRG 018)
7Lymphodepletion: Cy 500 mg/m^2 billed when Abecma uses 300
8Manufacturing failure / no product (do NOT bill Q2055)
9NDC-not-found (escalate to medical drug review w/ BMS chain-of-identity doc)
10Carvykti policy language applied (no neuro monitoring required, no lenalidomide-refractory gate — KarMMa-3 uses triple-class exposure)

Patient assistance — BMS Cell Therapy 360

  • BMS Cell Therapy 360 — benefits, PA, appeal, case mgmt; copay (commercial). Same hub as Breyanzi (the BMS CD19 CAR-T).
  • BMS Patient Assistance Foundation — free product for eligible uninsured / underinsured
  • Foundations: PAN, HealthWell, LLS Co-Pay (myeloma funds open quarterly)
  • Travel grants via BMS Cell Therapy 360 + International Myeloma Foundation for patients >50-100 mi from FACT center
BOXED WARNING — CRS, ICANS, HLH/MAS, prolonged cytopenias, secondary malignancies: Standard CAR-T 30-day post-infusion monitoring. Abecma does NOT carry the delayed Parkinsonism/MNT signal that Carvykti does — no extended ≥1-year neuro surveillance required. Tocilizumab (J3262) on hand per REMS; ICU backup required. CRS ~85% any-grade, ~5% Grade 3+ in KarMMa.
