(Active) Effective Date: N/A Glaucoma - Other glaucoma Chapter 7: Diseases of the eye and adnexa (H00-H59) Feed
Aqueous misdirection, right eye.
Medical necessity for the diagnosis and treatment of aqueous misdirection is established by the presence of signs and symptoms, such as elevated intraocular pressure, shallow anterior chamber, and/or optic nerve damage, posing a threat to the patient's vision.
Diagnosis and treatment of aqueous misdirection are typically managed by ophthalmologists or optometrists. Clinical responsibilities include performing a thorough eye examination, measuring intraocular pressure, assessing optic nerve health, and implementing appropriate treatment strategies to lower eye pressure and prevent vision loss.
In simple words: This code indicates a problem with fluid circulation in your right eye, leading to a type of glaucoma called aqueous misdirection or malignant glaucoma.
Aqueous misdirection, also known as malignant glaucoma, of the right eye. This condition is characterized by an abnormal flow of aqueous humor within the eye, leading to increased pressure and potential damage to the optic nerve.
Example 1: A 50-year-old patient presents with sudden onset of blurred vision and severe eye pain in their right eye following recent cataract surgery. After a comprehensive examination, including tonometry and gonioscopy, the ophthalmologist diagnoses aqueous misdirection and prescribes medication to lower intraocular pressure., A patient with a history of angle-closure glaucoma in both eyes develops symptoms in their right eye suggestive of aqueous misdirection. Diagnostic tests confirm the diagnosis, and the patient is started on a combination of topical and oral medications to manage the condition., A patient with a history of complicated eye surgery presents with a shallow anterior chamber and elevated intraocular pressure in their right eye. Following additional evaluation, the diagnosis of aqueous misdirection is confirmed, and laser peripheral iridotomy is performed to improve aqueous humor outflow.
Documentation should include details of the patient's symptoms (e.g., blurred vision, eye pain, halos), clinical findings (e.g., shallow anterior chamber, elevated intraocular pressure, optic nerve assessment), diagnostic tests performed (e.g., tonometry, gonioscopy, ultrasound biomicroscopy), and treatment plan.
