(Active) Effective Date: N/A Diseases of the eye and adnexa - Glaucoma 7 Feed
Aqueous misdirection, bilateral.
Medical necessity for treatment of aqueous misdirection is established by the presence of elevated intraocular pressure causing vision changes or threatening optic nerve health. The documentation should support the diagnosis and justify the chosen treatment approach.
Diagnosis and treatment of aqueous misdirection (malignant glaucoma) require specialized ophthalmological care. The physician's role involves a thorough eye examination, including tonometry to measure intraocular pressure, gonioscopy to assess the angle of the anterior chamber, and other diagnostic tests to confirm the diagnosis and determine the extent of the condition. Management options may include medications, laser procedures, or surgical intervention. Patient education and follow-up care are essential.
In simple words: Blockage of fluid drainage in both eyes, leading to increased pressure and potential vision problems.
Aqueous misdirection, a condition also known as malignant glaucoma, affecting both eyes.
Example 1: A patient presents with blurred vision, eye pain, and halos around lights in both eyes after recent cataract surgery. Examination reveals elevated intraocular pressure and a shallow anterior chamber, leading to a diagnosis of bilateral aqueous misdirection., A patient with a history of plateau iris syndrome develops sudden onset of severe eye pain and vision loss in both eyes. Diagnostic evaluation confirms aqueous misdirection with significantly increased intraocular pressure., A patient with a history of angle-closure glaucoma experiences worsening symptoms despite treatment. Examination reveals bilateral aqueous misdirection contributing to elevated intraocular pressure and optic nerve damage.
Documentation should include laterality (both eyes affected), the stage of glaucoma if applicable, associated symptoms (blurred vision, eye pain, halos), intraocular pressure readings, diagnostic test results (gonioscopy findings), and treatment plan.
** Excludes1: absolute glaucoma (H44.51-) congenital glaucoma (Q15.0) traumatic glaucoma due to birth injury (P15.3). Staging codes are not required for aqueous misdirection.
