H34.81
Central retinal vein occlusion
Clinical Classification Guidelines
7th Character Definition
One of the following 7th characters is to be assigned to codes in subcategory H34.81 to designate the severity of the occlusion:
Medical Intelligence & Overview
Central retinal vein occlusion (CRVO) is a common condition that affects the blood vessels of the retina, the light-sensitive layer at the back of the eye. It occurs when the main vein responsible for draining blood from the retina becomes blocked, leading to vision disturbances. Recognized under ICD-10 code H34.81, CRVO requires prompt attention to manage potential complications and preserve vision. This condition is often associated with underlying systemic health issues and can significantly impact a person's quality of life if not effectively addressed.
Causes & Symptoms
Clinical Causes: Atherosclerosis (hardening of the arteries) Hypertension (high blood pressure) Diabetes mellitus Glaucoma Blood clotting disorders Inflammatory conditions affecting blood vessels Age-related changes in blood vessels Smoking and lifestyle factors Obesity
Key Symptoms: Sudden, painless vision loss in one eye Blurred or distorted vision Floaters or dark spots in the visual field In severe cases, a significant decrease in visual acuity Potential visual shadowing if complications such as macular edema develop
Diagnostic & Treatment
Diagnosis Path: Visual acuity test to assess clarity of vision Fundoscopy (slit-lamp examination) to observe the retinal vessels and identify hemorrhages or swelling Optical coherence tomography (OCT) to measure retinal thickness and detect edema Fluorescein angiography to evaluate blood flow and identify blockage areas Assessment of underlying health conditions that may contribute to CRVO
Treatment Protocols: Intravitreal injections of anti-VEGF agents to reduce macular edema and improve visual outcomes Steroid injections to decrease inflammation and swelling Laser therapy to address areas of abnormal blood vessel growth or swelling Controlling systemic health conditions such as hypertension, diabetes, and blood clotting disorders Regular follow-up examinations for monitoring progression and response to treatment
Clinical Advice & FAQs
Billing Guidance
Is H34.81 a billable ICD-10 code?
Yes, H34.81 is a specific, billable code that can be used to indicate a diagnosis for reimbursement purposes.
Documentation
How do I report H34.81?
