About C69.40
C69.40 is the ICD-10-CM diagnosis code for malignant neoplasm of unspecified ciliary body. 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 billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within C69.4, choose C69.40 (unspecified ciliary body) only when documentation doesn't support a more specific option: right ciliary body (C69.41) and left ciliary body (C69.42).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 124 (Other Disorders of the Eye with MCC or Thrombolytic Agent, relative weight 1.2471) and DRG 125 (Other Disorders of the Eye without MCC, relative weight 0.7702), in MDC 02 (Diseases and Disorders of the Eye), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 190.0 (malignant neoplasm of eyeball, except conjunctiva, cornea, retina, and choroid).
