Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to H40.053: its own notes plus those printed at H40 and Chapter 7. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

From H40 Glaucoma applies to 252 codes
  • absolute glaucoma (H44.51-)
  • congenital glaucoma (Q15.0)
  • traumatic glaucoma due to birth injury (P15.3)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 7 (H00-H59) Diseases of the eye and adnexa applies to 2,677 codes
  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)

Notes

General instructions on how these codes are used.

From Chapter 7 (H00-H59) Diseases of the eye and adnexa applies to 2,677 codes
  • Use an external cause code following the code for the eye condition, if applicable, to identify the cause of the eye condition

Clinical InformationClinical

  • Ocular Hypertension

    a condition in which the intraocular pressure is elevated above normal and which may lead to glaucoma.

Patient EducationClinical

Glaucoma

Glaucoma is a group of diseases that can damage the optic nerve of one, or both, of your eyes. This can result in vision loss. There are different types of glaucoma, but the most common type is open-angle glaucoma. Other less common types include angle-closure glaucoma, and congenital glaucoma.

Questions About H40.053Overview

What is the ICD-10 code for ocular hypertension, bilateral?

The ICD-10-CM code for ocular hypertension, bilateral is H40.053 (sometimes written as H40053). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is H40.053 (Ocular hypertension) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report ocular hypertension, bilateral on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does H40.053 group to?

When ocular hypertension, bilateral is the principal diagnosis on an inpatient stay, it groups to MS-DRG 125, 124, with relative weights from 0.7699 to 1.2470 depending on complications. Higher weights mean higher Medicare reimbursement.
