About C69

C69 is the ICD-10-CM diagnosis code for malignant neoplasm of eye and adnexa. It belongs to block C69-C72 (malignant neoplasms of eye, brain and other parts of central nervous system) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 9 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: C69.0 (conjunctiva), C69.1 (cornea), C69.2 (retina), C69.3 (choroid), C69.4 (body), C69.5 (duct), C69.6 (orbit), C69.8 (adnexa) and 1 more.

Don't report C69 together with the conditions in its Excludes1 note: malignant neoplasm of connective tissue of eyelid (C49.0), malignant neoplasm of eyelid (skin) (C43.1-, C44.1-) and malignant neoplasm of optic nerve (C72.3-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
