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 an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

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

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

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 to one of these instead C92.1

3 child codes. Green means billable.
