ICD-10-CM Billable Code

H21.229

Degeneration of ciliary body, unspecified eye

Clinical Classification Guidelines

Medical Intelligence & Overview

Degeneration of the ciliary body refers to a gradual deterioration of the tissue within the eye responsible for controlling the shape of the lens and producing aqueous humor, which supplies nutrients to certain parts of the eye. When this degeneration occurs, it can impact vision and eye health. ICD-10 code H21.229 specifically denotes an unspecified eye affected by this condition, meaning detailed information about which eye is involved isn’t specified.

Causes & Symptoms

Clinical Causes: Age-related changes: natural aging can cause degeneration of eye structures including the ciliary body. Chronic inflammation: long-term inflammation inside the eye, such as uveitis, can damage the ciliary body tissue. Genetic factors: inherited conditions may predispose individuals to degeneration of eye tissues. Eye trauma: physical injuries to the eye can lead to deterioration of the ciliary body. Degenerative eye diseases: conditions such as glaucoma or other degenerative disorders may involve the ciliary body. Systemic health issues: diseases like diabetes or autoimmune conditions can contribute to tissue degeneration in the eye.

Key Symptoms: Blurred vision or difficulty focusing Reduced ability to see fine details Sensitivity to light (photophobia) Eye redness or discomfort Increased intraocular pressure (may be associated with glaucoma) Possible visible changes in eye appearance (less common)

Diagnostic & Treatment

Diagnosis Path: Visual acuity testing: to assess how well vision is functioning Slit-lamp examination: allows detailed inspection of eye structures including the ciliary body Gonioscopy: examines the front part of the eye and angle structures Ultrasound biomicroscopy: imaging technique that visualizes the anterior segment of the eye Intraocular pressure measurement: checks for elevated pressure indicative of glaucoma

Treatment Protocols: Monitoring: regular eye exams to track progression Medications: eye drops or systemic drugs to manage intraocular pressure or treat underlying inflammation Addressing underlying conditions: controlling systemic diseases such as diabetes or autoimmune disorders Surgical intervention: procedures may be considered in advanced cases or if complications like glaucoma develop Visual aids: glasses or specialized devices to support vision if decline occurs

Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.
