ICD Code H40-

ICD code H40- is used to identify various types of glaucoma, a group of eye conditions that damage the optic nerve and can lead to vision loss or blindness.

1. Presence of elevated intraocular pressure as measured by tonometry

2. Characteristic optic nerve head changes, such as increased cupping or notching

3. Progressive visual field loss consistent with glaucomatous damage

4. Open or closed anterior chamber angle confirmed by gonioscopy

5. Absence of secondary causes for optic neuropathy (e.g., trauma, inflammation, vascular occlusion)

6. Symptoms may include gradual peripheral vision loss, halos around lights, or eye pain (in some subtypes)

7. Family history of similar optic nerve or visual field changes may be present

Relevant CPT codes that may be used to treat ICD code H40- include:

- 92002: Ophthalmological services; new patient, evaluation and management

- 92004: Ophthalmological services; comprehensive, new patient

- 92012: Ophthalmological services; established patient, evaluation and management

- 92014: Ophthalmological services; comprehensive, established patient

- 92100: Tonometry (measurement of intraocular pressure)

- 92133: Scanning computerized ophthalmic diagnostic imaging, posterior segment, with interpretation and report, unilateral or bilateral; optic nerve

- 92134: Scanning computerized ophthalmic diagnostic imaging, posterior segment, with interpretation and report, unilateral or bilateral; retina

- 92250: Fundus photography with interpretation and report

- 99201–99215: Evaluation and management services (office or other outpatient visits)

- 65855: Trabeculoplasty by laser surgery

- 66170: Trabeculectomy ab externo in glaucoma

- 66180: Aqueous shunt to extraocular reservoir

- 66710: Ciliary body destruction; cyclophotocoagulation, laser

- 66984: Extracapsular cataract removal with insertion of intraocular lens prosthesis
