ICD-10: Get Ready to Update Coding

By Maria Sampalis, OD


The new ICD-10 codes now take effect October 2015. Train your staff (and yourself) with this primer and resource guide on new codes for common eye conditions.


UNDERSTAND MAJOR CHANGES. ICD-10 adds more codes to replace the use of coding modifiers.
USE KEY FREE RESOURCE. Online resources, some of them free, help you transition to ICD-10.

GET STAFF ON BOARD. Devote 10-15 minutes per staff meeting to practicing coding in specific areas such as myopia, cataract, diabetic eye exams and glaucoma.

Converting to ICD-10 will provide more accurate coding and provide more detailed information on the condition such as severity and location in the eye. Here is a summary of this major change, along with examples of how this coding will be updated in several areas of your practice. ICD-10 will help ensure what you should be doing already–coding to the highest level of specificity.

The deadline to update from ICD-9 to ICD-10 coding has been extended by one year to October 2015. The conversion will expand 17,000 codes to over 140,000 codes! Use the extra time to prepare your practice for this new coding system.

You can use this online guide to conduct an introductory staff meeting on the ICD-10 change. Then, in each subsequent meeting, you can devote 10-15 minutes to address a different aspect of the practice. For instance, one meeting could focus on coding changes for myopia, while the next could address changes to cataract coding, and another could look at coding for diabetic retinopathy or glaucoma.

Major Change:

In ICD-10, more codes to choose from replaces the use of modifiers. The new system will take getting used to, but once you and your staff have adapted, coding should be faster and more efficient without the need to add modifiers.

In ICD-10, eye codes are a subcategory under H. And the category of the eye is separated by a series of numbers. For example, the lens is H25-H28, where glaucoma is H40-H42.

H52.1, but there is more. If you needed to code exactly which eye is affected, then H52.11 would be myopia for the right eye.

H52.10 myopia, unspecified eye
H52.11 myopia, right eye
H52.12 myopia, left eye
H52.13 myopia bilateral



cortical cataract: 366.15

Cortical cataract: H25.01
Cortical age-related cataract

Cortical age-related cataract, right eye

Cortical age-related cataract, left eye

Cortical age-related cataract, bilateral

Cortical age-related cataract, unspecified eye

Diabetic Eye Exam


Combine: 250.50 Diabetes with ophthalmic manifestations, type II or unspecified type, not stated as uncontrolled
With: 362.04 Mild nonproliferation diabetic retinopathy

You would use E11.32- Type 2 diabetes mellitus with mild nonproliferative diabetic retinopathy



365.00 Preglaucoma, unspecified

365.01 Open angle with borderline findings, low risk

365.02 Anatomical narrow angle borderline glaucoma

365.03 Steroid responders borderline glaucoma

H40.051 …… right eye
H40.052 …… left eye
H40.053 …… bilateral
H40.059 …… unspecified eye
