Buddy Documentation Tip

HCC Buddy guidance
Documentation must confirm prior remission and relapse with the 11q23/KMT2A rearrangement, ideally confirmed at relapse as clonal evolution may occur.
Duration of first remission, prior treatment regimens, and updated molecular/cytogenetic testing at relapse must be recorded.
Transplant candidacy assessment, donor search status, and salvage treatment plan should be documented.

MEAT Support

HCC Buddy guidance
Documentation must confirm prior remission and relapse with the 11q23/KMT2A rearrangement, ideally confirmed at relapse as clonal evolution may occur.
Duration of first remission, prior treatment regimens, and updated molecular/cytogenetic testing at relapse must be recorded.
Transplant candidacy assessment, donor search status, and salvage treatment plan should be documented.

Audit Caution

HCC Buddy guidance
Confirm the 11q23 rearrangement persists at relapse, as some relapses may show clonal evolution with loss of the original abnormality or acquisition of new changes.
Therapy-related AML at relapse may have different biology than de novo disease.
Duration of first remission (less than vs.
greater than 12 months) is a key prognostic factor that should be documented.

Common Mistakes

HCC Buddy guidance
C92.60 (AML with 11q23 not in remission) is for primary refractory disease.
C92.61 (AML with 11q23 in remission) is for controlled disease.
C92.02 (AML in relapse) is less specific and does not capture the cytogenetic abnormality.
C92.52 (AMML in relapse) may overlap clinically but does not specify the 11q23 abnormality.

Last updated: FY2026 ICD-10-CM Apr update, Apr 1, 2026 through Sep 30, 2026. CMS-HCC V28 is 100% phased in for payment year 2026.

Is C92.62 an HCC code?

Yes. C92.62 maps to Metastatic Cancer and Acute Leukemia under the CMS-HCC V28 risk adjustment model (and Metastatic Cancer and Acute Leukemia under V24).

RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.

MEAT Criteria for C92.62

For C92.62to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically, it has to be re-documented and supported each calendar year.

  • MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
  • EEvaluate: test results, medication response, or physical findings reviewed by the provider
  • AAssess: explicit mention in the assessment or plan with acknowledgment of status
  • TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis

Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed C92.62 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

C92.62 is the ICD-10-CM diagnosis code for acute myeloid leukemia with 11q23-abnormality in relapse. A specific type of acute myeloid leukemia with a chromosomal abnormality (11q23) where the cancer has returned after a period of remission. C92.62 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering malignant neoplasms of lymphoid, hematopoietic and related tissue (c81-c96).

Under the CMS-HCC V28 risk adjustment model, C92.62 maps to Metastatic Cancer and Acute Leukemia (HCC 17) with a community, non-dual, aged base RAF weight of 0.368. Under the older V24 model, C92.62 mapped to the same category but with a base RAF weight of 2.484, V28 recalibrated weights across the entire model. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.

Document both the cytogenetic abnormality and the relapse status in the medical record. Because C92.62 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.

HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for C92.62 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • Document both the cytogenetic abnormality and the relapse status in the medical record
  • Distinguish between initial presentation and relapse based on treatment history

Clinical Significance

Acute myeloid leukemia with 11q23-abnormality in relapse indicates recurrence of this cytogenetically defined AML subtype after prior remission. Relapsed AML with 11q23 rearrangements carries a poor prognosis, though outcomes vary by the specific fusion partner. Salvage therapy followed by allogeneic stem cell transplantation offers the best chance for long-term survival in eligible patients.

Documentation Requirements

  • Documentation must confirm prior remission and relapse with the 11q23/KMT2A rearrangement, ideally confirmed at relapse as clonal evolution may occur.
  • Duration of first remission, prior treatment regimens, and updated molecular/cytogenetic testing at relapse must be recorded.
  • Transplant candidacy assessment, donor search status, and salvage treatment plan should be documented.

Commonly Confused Codes

  • C92.60 (AML with 11q23 not in remission) is for primary refractory disease.
  • C92.61 (AML with 11q23 in remission) is for controlled disease.
  • C92.02 (AML in relapse) is less specific and does not capture the cytogenetic abnormality.
  • C92.52 (AMML in relapse) may overlap clinically but does not specify the 11q23 abnormality.
