H21.43
Pupillary membranes, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Bilateral pupillary membranes refer to abnormal formations that develop across the pupils of both eyes. These membranes are remnants from fetal development that usually regress before birth but can persist in some individuals. Their presence can influence vision and eye health depending on their size, location, and impact on the iris and pupil. Recognizing this condition is important for proper eye care and management.
Causes & Symptoms
Clinical Causes: Congenital developmental remnants from fetal vasculature that failed to regress during gestation Genetic factors contributing to abnormal eye tissue development History of intrauterine infections or maternal health issues affecting fetal eye development Previously undiagnosed or asymptomatic persistent pupillary membrane formation
Key Symptoms: Obvious visible membranes across the pupils when looking into the eyes Potential reduction in visual clarity or acuity if membranes obstruct the central visual axis Possible sensitivity to light (photophobia) Irregular pupils or differences in pupil size (anisocoria) if membranes affect iris shape Generally no pain or discomfort unless associated with other eye conditions
Diagnostic & Treatment
Diagnosis Path: Slit-lamp biomicroscopy to visualize the membranes across the pupils Assessment of visual acuity to determine if there is impairment Pupil light reaction tests to examine pupil responsiveness Additional imaging, such as anterior segment optical coherence tomography (OCT), if detailed visualization is needed
Treatment Protocols: Observation and regular monitoring for any changes in the membranes or vision Laser procedures to carefully remove or reduce the membranes if they obstruct vision Surgical intervention in rare cases where membranes significantly impair visual function Corrective glasses or contact lenses to improve visual acuity if needed Addressing any associated eye conditions that may arise
Clinical Advice & FAQs
Billing Guidance
Is H21.43 a billable ICD-10 code?
Yes, H21.43 is a specific, billable code that can be used to indicate a diagnosis for reimbursement purposes.
Documentation
How do I report H21.43?
Clinical documentation must specify the nature of Pupillary membranes, bilateral and any associated comorbidities for accurate reporting.
