Is D48 a billable ICD-10-CM code?

No. D48 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does D48 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 D48?

D48 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

D48

D48 — Neoplasm of uncertain behavior of other and unspecified sites

Non-billable headerICD-10-CM

D48 is a non-billable header ICD-10-CM code for neoplasm of uncertain behavior of other and unspecified sites. 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.

neurofibromatosis (nonmalignant) (Q85.0-)

Other codes that can never be billed with D48

These codes carry an Excludes1 note pointing at D48. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D48 alone.

D37Neoplasm of uncertain behavior of oral cavity and digestive organs
D37.0Neoplasm of uncertain behavior of lip, oral cavity and pharynx
D37.8Neoplasm of uncertain behavior of other specified digestive organs
D38Neoplasm of uncertain behavior of middle ear and respiratory and intrathoracic organs
D38.5Neoplasm of uncertain behavior of other respiratory organs
D43Neoplasm of uncertain behavior of brain and central nervous system
D48.0Neoplasm of uncertain behavior of bone and articular cartilage
D48.1Neoplasm of uncertain behavior of connective and other soft tissue

Risk adjustment

D48 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 D48

9 child codes. Green means billable.
