ICD-10: H40.839

ICD-10 code H40.839 refers to "Aqueous misdirection, unspecified eye," which is classified under the category of diseases affecting the eye and adnexa. Here are the key clinical details and descriptions associated with this code:

• Definition: Aqueous misdirection is a condition characterized by the abnormal accumulation of aqueous humor in the eye, leading to increased pressure that can affect the retina and optic nerve. This condition can result in visual impairment if not managed properly [1][13].

• Classification: The code H40.839 is a billable diagnosis code, meaning it can be used for reimbursement purposes in medical billing. It is part of the broader classification of glaucoma-related conditions, specifically under the range of aqueous misdirection codes (H40.831-H40.839) [1][5][14].

• Clinical Significance: The condition is significant as it can lead to complications such as vision loss if the pressure within the eye is not controlled. It is essential for healthcare providers to recognize and treat this condition promptly to prevent further ocular damage [13][15].

• Related Codes: While H40.839 is specific to aqueous misdirection, it is important to note that there are other related codes within the H40 range that pertain to different types of glaucoma and eye conditions, which may be relevant in a comprehensive clinical assessment [9][14].

• Synonyms: Aqueous misdirection is also referred to as "aqueous humor misdirect" or "shallow anterior chamber of the eye," indicating the nature of the fluid misdirection within the eye [3][5].

In summary, H40.839 is a critical code for identifying and managing aqueous misdirection, which requires careful clinical attention to prevent potential complications related to increased intraocular pressure.
