H11.10 is a billable diagnosis code used to specify a medical diagnosis of unspecified conjunctival degenerations. The code H11.10 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 H11.10 might also be used to specify conditions or terms like bulbar conjunctival degeneration, conjunctival degeneration, conjunctival degenerations and deposits, spheroidal degeneration of conjunctiva or subconjunctival degeneration.

Unspecified diagnosis codes like H11.10 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


Eye Diseases

Some eye problems are minor and don't last long. But some can lead to a permanent loss of vision.

Common eye problems include

Your best defense is to have regular checkups, because eye diseases do not always have symptoms. Early detection and treatment could prevent vision loss. See an eye care professional right away if you have a sudden change in vision, if everything looks dim, or if you see flashes of light. Other symptoms that need quick attention are pain, double vision, fluid coming from the eye, and inflammation.
