Code Description

ICD-10 H11.031 is a billable code used to indicate a diagnosis of double pterygium of right eye.

Key Diagnostic Point:

Double pterygium of the right eye is characterized by the presence of two pterygia, which are triangular-shaped growths of conjunctival tissue that extend onto the cornea. This condition typically arises due to prolonged exposure to UV light, dust, and wind, leading to conjunctival inflammation and fibrovascular proliferation. The anatomy involved includes the conjunctiva, which is the clear membrane covering the white part of the eye, the sclera, and the cornea. Clinically, patients may present with symptoms such as redness, irritation, and visual disturbances if the pterygia encroach upon the visual axis. Disease progression can lead to increased growth, potential astigmatism, and cosmetic concerns. Diagnostic considerations include a thorough eye examination, where the ophthalmologist assesses the extent of the pterygia and any associated corneal changes. Imaging techniques may be utilized to evaluate the depth of invasion into the cornea. Treatment options range from observation for asymptomatic cases to surgical excision for symptomatic or visually impairing pterygia.

Enhanced Specificity

ICD-10 Improvements

Double pterygium can significantly affect a patient's quality of life, leading to discomfort and visual impairment. The condition is more prevalent in populations with high UV exposure, such as those living in sunny climates. Understanding the epidemiology of pterygium can aid in developing preventive strategies and improving patient education on UV protection. Quality measures may include tracking surgical outcomes and patient satisfaction post-treatment.

ICD-9 vs ICD-10

Double pterygium can significantly affect a patient's quality of life, leading to discomfort and visual impairment. The condition is more prevalent in populations with high UV exposure, such as those living in sunny climates. Understanding the epidemiology of pterygium can aid in developing preventive strategies and improving patient education on UV protection. Quality measures may include tracking surgical outcomes and patient satisfaction post-treatment.

Reimbursement & Billing Impact

Reimbursement considerations include verifying the medical necessity for surgical intervention if performed. Common denials may arise from insufficient documentation of the condition's impact on vision or quality of life. Coding best practices recommend using precise terminology and ensuring that all relevant clinical details are included in the patient's medical record to support the claim.

Frequently Asked Questions

What specific conditions are covered by H11.031?

H11.031 specifically covers double pterygium affecting the right eye. It includes cases where both pterygia are present and may affect visual acuity or cause discomfort.

When should H11.031 be used instead of related codes?

H11.031 should be used when both pterygia are present in the right eye, distinguishing it from H11.030, which is used for a single pterygium. Accurate documentation of the condition's bilateral nature is essential.

What documentation supports H11.031?

Documentation should include a detailed eye examination report, noting the presence and extent of both pterygia, symptoms experienced by the patient, and any visual impairment or treatment plans.
