ICD-10-CM Code: H40.2214 - Chronic Angle-Closure Glaucoma, Right Eye, Indeterminate Stage

Chronic angle-closure glaucoma, a serious condition affecting the eye, is represented by this code. The angle between the iris and cornea narrows, obstructing the flow of aqueous humor. This buildup of pressure within the eye can ultimately lead to vision loss. This specific code denotes chronic angle-closure glaucoma affecting the right eye where the stage of the condition is not yet determined.

Category: Diseases of the eye and adnexa > Glaucoma

This code belongs to a broader category of eye diseases and specifically targets a type of glaucoma. It's vital to correctly assign this code to ensure accurate documentation and appropriate medical billing.

Description

The description for H40.2214 highlights several key aspects of the condition:

Chronic Angle-Closure Glaucoma: This signifies a persistent narrowing of the angle, leading to chronic intraocular pressure.

Right Eye: The code applies specifically to the right eye, differentiating it from left eye cases.

Indeterminate Stage: This signifies that the severity of the glaucoma is unclear at this time.

Excludes

The ICD-10-CM code system uses excludes notes to clarify boundaries and differentiate similar conditions. This code excludes other conditions which may seem related, ensuring that coding remains accurate and consistent:

Excludes 1: Aqueous misdirection (H40.83-) Malignant glaucoma (H40.83-)

Excludes 2: Absolute glaucoma (H44.51-) Congenital glaucoma (Q15.0) Traumatic glaucoma due to birth injury (P15.3) Diabetes mellitus related eye conditions (E09.3-, E10.3-, E11.3-, E13.3-)

Usage

This code applies to patients diagnosed with chronic angle-closure glaucoma in their right eye. The stage of glaucoma remains undetermined at the time of coding. This could indicate:

Initial diagnosis where the severity is not yet fully assessed.

The condition may not be severe enough for a definite stage assignment.

Ongoing monitoring to determine the progression of the glaucoma.

Examples of Correct Application

These examples illustrate situations where this code would be appropriately used, highlighting different clinical scenarios.

Example 1: Initial Diagnosis and Monitoring A patient experiences blurred vision and haloes around lights. During an ophthalmological exam, the physician identifies chronic angle-closure glaucoma in the right eye, but due to early stage, the stage cannot be determined definitively. The patient will be monitored for progression and further evaluation. The ICD-10-CM code H40.2214 is applied for the initial diagnosis and ongoing management.

Example 2: Laser Treatment for Angle-Closure Glaucoma A patient with a history of right eye angle-closure glaucoma visits their ophthalmologist for a follow-up exam. The stage of glaucoma is still indeterminate; the physician recommends a laser iridotomy procedure. This surgical treatment is aimed at improving drainage of aqueous humor. This example emphasizes using H40.2214 even for patients undergoing procedures related to the condition.

Example 3: Flare-Up of Symptoms A patient previously diagnosed with right eye angle-closure glaucoma experiences sudden increased pressure in the eye accompanied by pain and blurred vision. This represents a flare-up of symptoms. H40.2214 is used, while the patient is treated with medications and monitored to control the flare-up.

Coding Considerations

There are vital coding considerations to ensure accuracy:

Stage of Glaucoma: The stage of glaucoma is crucial. Accurate coding relies on knowing the stage and using the specific code: Mild: H40.2211 Moderate: H40.2212 Severe: H40.2213 Use H40.2214 when the stage is indeterminate.

Lateralization: This code pertains to the right eye, clearly defining which side is affected. For the left eye, code H40.2224 is used. For bilateral cases, codes H40.2114 and H40.2124 are used.
