D16.6

D16.6 — Benign neoplasm of vertebral column

Billable / specific codeICD-10-CM

D16.6 is a billable, specific ICD-10-CM code for benign neoplasm of vertebral column. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

benign neoplasm of sacrum and coccyx (D16.8)

Excludes1 inherited from the categories above D16.6

These are not written on D16.6, but they bind it: a note on a category applies to every code beneath it. Billing D16.6 with anything listed here is a denial.

Written on D16 — Benign neoplasm of bone and articular cartilage

benign neoplasm of connective tissue of ear (D21.0)
benign neoplasm of connective tissue of eyelid (D21.0)
benign neoplasm of connective tissue of larynx (D14.1)
benign neoplasm of connective tissue of nose (D14.0)
benign neoplasm of synovia (D21.-)

Other codes that can never be billed with D16.6

These codes carry an Excludes1 note pointing at D16.6. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D16.6 alone.

Risk adjustment

D16.6 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.

Medicare coverage

D16.6 is named in 10 Medicare coverage policies — 10 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
