Is D38 a billable ICD-10-CM code?

No. D38 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does D38 sit in the tabular list?

Neoplasms (C00-D49), in the block Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes (D37-D48).

What cannot be coded together with D38?

D38 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

D38

D38 — Neoplasm of uncertain behavior of middle ear and respiratory and intrathoracic organs

Non-billable headerICD-10-CM

D38 is a non-billable header ICD-10-CM code for neoplasm of uncertain behavior of middle ear and respiratory and intrathoracic organs. 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.

neoplasm of uncertain behavior of heart (D48.7)

Other codes that can never be billed with D38

These codes carry an Excludes1 note pointing at D38. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D38 alone.

D37.0Neoplasm of uncertain behavior of lip, oral cavity and pharynx
D44Neoplasm of uncertain behavior of endocrine glands
D48.0Neoplasm of uncertain behavior of bone and articular cartilage
D48.1Neoplasm of uncertain behavior of connective and other soft tissue

Risk adjustment

D38 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 D38

7 child codes. Green means billable.
