C69.6Malignant neoplasm of orbit

Non-billable headerICD-10-CM

C69.6 is a non-billable header ICD-10-CM code for malignant neoplasm of orbit. 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.

  • malignant neoplasm of orbital bone (C41.0)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Malignant neoplasm of connective tissue of orbit
  • Malignant neoplasm of extraocular muscle
  • Malignant neoplasm of peripheral nerves of orbit
  • Malignant neoplasm of retrobulbar tissue
  • Malignant neoplasm of retro-ocular tissue

Other codes that can never be billed with C69.6

These codes carry an Excludes1 note pointing at C69.6. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C69.6 alone.

  • C71Malignant neoplasm of brain
  • C47.0Malignant neoplasm of peripheral nerves of head, face and neck
  • C49.0Malignant neoplasm of connective and soft tissue of head, face and neck

Risk adjustment

C69.6 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.

Code to one of these instead C69.6

3 child codes. Green means billable.
