Is C92.1 a billable ICD-10-CM code?

No. C92.1 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does C92.1 sit in the tabular list?

Neoplasms (C00-D49), in the block Malignant neoplasms of lymphoid, hematopoietic and related tissue (C81-C96).

What cannot be coded together with C92.1?

C92.1 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above C92.1 (C92) and apply to it just the same.

C92.1

C92.1 — Chronic myeloid leukemia, BCR/ABL-positive

Non-billable headerICD-10-CM

C92.1 is a non-billable header ICD-10-CM code for chronic myeloid leukemia, bcr/abl-positive. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

atypical chronic myeloid leukemia BCR/ABL-negative (C92.2-)
chronic myelomonocytic leukemia (C93.1-)
chronic myeloproliferative disease (D47.1)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Chronic myelogenous leukemia, Philadelphia chromosome (Ph1) positive
Chronic myelogenous leukemia, t(9;22) (q34;q11)
Chronic myelogenous leukemia with crisis of blast cells

Excludes1 inherited from the categories above C92.1

These are not written on C92.1, but they bind it: a note on a category applies to every code beneath it. Billing C92.1 with anything listed here is a denial.

Written on C92 — Myeloid leukemia

personal history of leukemia (Z85.6)

Other codes that can never be billed with C92.1

These codes carry an Excludes1 note pointing at C92.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C92.1 alone.

C92.0Acute myeloblastic leukemia
D47.1Chronic myeloproliferative disease
D72.825Bandemia

Risk adjustment

C92.1 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code history

C92.1 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead C92.1

3 child codes. Green means billable.
