Is D20 a billable ICD-10-CM code?

No. D20 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does D20 sit in the tabular list?

Neoplasms (C00-D49), in the block Benign neoplasms, except benign neuroendocrine tumors (D10-D36).

What cannot be coded together with D20?

D20 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

D20

D20 — Benign neoplasm of soft tissue of retroperitoneum and peritoneum

Non-billable headerICD-10-CM

D20 is a non-billable header ICD-10-CM code for benign neoplasm of soft tissue of retroperitoneum and peritoneum. 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.

benign lipomatous neoplasm of peritoneum and retroperitoneum (D17.79)
benign neoplasm of mesothelial tissue (D19.-)

Other codes that can never be billed with D20

These codes carry an Excludes1 note pointing at D20. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D20 alone.

D21Other benign neoplasms of connective and other soft tissue

Risk adjustment

D20 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 D20

2 child codes. Green means billable.
