Is D02 a billable ICD-10-CM code?

No. D02 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does D02 sit in the tabular list?

Neoplasms (C00-D49), in the block In situ neoplasms (D00-D09).

What cannot be coded together with D02?

D02 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

D02

D02 — Carcinoma in situ of middle ear and respiratory system

Non-billable headerICD-10-CM

D02 is a non-billable header ICD-10-CM code for carcinoma in situ of middle ear and respiratory system. 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.

melanoma in situ (D03.-)

Use additional code

Add a secondary code to capture the detail described below.

code to identify:
exposure to environmental tobacco smoke (Z77.22)
exposure to tobacco smoke in the perinatal period (P96.81)
history of tobacco dependence (Z87.891)
occupational exposure to environmental tobacco smoke (Z57.31)
tobacco dependence (F17.-)
tobacco use (Z72.0)

Other codes that can never be billed with D02

These codes carry an Excludes1 note pointing at D02. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D02 alone.

D00.0Carcinoma in situ of lip, oral cavity and pharynx

Risk adjustment

D02 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 D02

5 child codes. Green means billable.
