Valid for Submission
H35.40 is a billable diagnosis code used to specify a medical diagnosis of unspecified peripheral retinal degeneration. The code H35.40 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code H35.40 might also be used to specify conditions or terms like peripheral degeneration of retina of bilateral eyes, peripheral drusen, peripheral retinal degeneration, peripheral retinal degeneration of left eye or peripheral retinal degeneration of right eye.
Unspecified diagnosis codes like H35.40 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Information for Patients
The retina is a layer of tissue in the back of your eye that senses light and sends images to your brain. In the center of this nerve tissue is the macula. It provides the sharp, central vision needed for reading, driving and seeing fine detail.
Retinal disorders affect this vital tissue. They can affect your vision, and some can be serious enough to cause blindness. Examples are
- Macular degeneration - a disease that destroys your sharp, central vision
- Diabetic eye disease
- Retinal detachment - a medical emergency, when the retina is pulled away from the back of the eye
- Retinoblastoma - cancer of the retina. It is most common in young children.
- Macular pucker - scar tissue on the macula
- Macular hole - a small break in the macula that usually happens to people over 60
- Floaters - cobwebs or specks in your field of vision
