Is ICD-10-CM code H52 billable?

No, H52 (Disorders of refraction and accommodation) is a non-billable ICD-10-CM code. It must be coded to a more specific subcategory before it can be used for reimbursement.

What chapter does ICD-10-CM code H52 belong to?

H52 belongs to Chapter 7 of the ICD-10-CM tabular list: H00–H59 (Diseases of the Eye and Adnexa).

H52Not billable, use a more specific code below

Disorders of refraction and accommodation

In Disorders of ocular muscles, binocular movement, accommodation and refraction (H49-H52), chapter 7: Diseases of the Eye and Adnexa

37 billable codes under H52: none are a CC or MCC; none map to an HCC.

Instructional notes

Also applies, from Disorders of ocular muscles, binocular movement, accommodation and refraction (H49-H52)

These notes sit on H49-H52 and apply to every code under it, including H52.

Excludes2: not included here, code separately if applicable

nystagmus and other irregular eye movements (H55)

Covers coding glaucoma by type, eye, and stage, including bilateral cases and stage changes, and coding blindness or low vision when the impairment category is undocumented.

All codes under H52

H52 can't be used on a claim. Pick a billable code below; grey headings group them.

H52 MS-DRGs

As the principal diagnosis, the billable codes under H52 group to MS-DRG 124, 125, or 123 (v44.0). Which one applies depends on procedures performed, secondary diagnoses (CC/MCC), and the patient's age and discharge status.

DRG 124 Other Disorders of the Eye with MCC or Thrombolytic Agent (33 of 37 codes)
DRG 125 Other Disorders of the Eye without MCC (33 of 37 codes)
DRG 123 Neurological Eye Disorders (4 of 37 codes)

About the condition

Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.

Refractive Errors

The cornea and lens of your eye bend (refract) light rays to focus them on the retina. Refractive errors happen when the shape of your eye prevents light from focusing correctly on the retina. This causes blurry vision. Changes in the eye's shape affect how light rays bend and focus, leading to vision problems.

Code history

Valid since FY2016, when ICD-10-CM took effect on October 1, 2015. No changes since.
