C69 is a non-billable ICD-10-CM category code for malignant neoplasm of eye and adnexa, so it cannot be submitted on claims. Use a more specific code from this category instead, such as C69.00, C69.01, C69.02, and C69.10.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to C69: its own notes plus those printed at Chapter 2. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

  • malignant neoplasm of connective tissue of eyelid (C49.0)
  • malignant neoplasm of eyelid (skin) (C43.1-, C44.1-)
  • malignant neoplasm of optic nerve (C72.3-)

Notes

General instructions on how these codes are used.

From Chapter 2 (C00-D49) Neoplasms applies to 1,730 codes
  • Functional activity
  • All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm.
  • Morphology [Histology]
  • Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes.
  • Primary malignant neoplasms overlapping site boundaries
  • A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned.
  • Malignant neoplasm of ectopic tissue
  • Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).

Patient EducationClinical

Eye Cancer

Cancer of the eye is uncommon. It can affect the outer parts of the eye, such as the eyelid, which are made up of muscles, skin and nerves. If the cancer starts inside the eyeball it's called intraocular cancer. The most common intraocular cancers in adults are melanoma and lymphoma.

Questions About C69Overview

What is the ICD-10 code for malignant neoplasm of eye and adnexa?

C69 is the ICD-10-CM category for malignant neoplasm of eye and adnexa, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is C69 (Malignant neoplasm of eye and adnexa) a billable code?

No. This is a category header that groups the codes for malignant neoplasm of eye and adnexa, and headers cannot be submitted on claims. Claims for malignant neoplasm of eye and adnexa need a more specific code from this category, such as C69.00, C69.01, and C69.02.

Can C69 be reported with C49.0?

Not as a rule. The Excludes1 note on C69 lists "malignant neoplasm of connective tissue of eyelid (C49.0)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
