About C69.6

C69.6 is the ICD-10-CM diagnosis code for malignant neoplasm of orbit. It belongs to category C69 (malignant neoplasm of eye and adnexa), 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 3 subcodes must be used instead.

Within C69 (malignant neoplasm of eye and adnexa), C69.6 is specifically for malignant neoplasm of orbit. Related codes cover conjunctiva (C69.0), cornea (C69.1), retina (C69.2), choroid (C69.3), ciliary body (C69.4), lacrimal gland and duct (C69.5), overlapping sites of eye and adnexa (C69.8) and unspecified site of eye (C69.9).

To report this condition, pick the subcode that matches the documentation: C69.60 (orbit), C69.61 (orbit) and C69.62 (orbit).

Don't report C69.6 together with the conditions in its Excludes1 note: malignant neoplasm of orbital bone (C41.0).

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