Glaucoma ICD-10-CM Codes

What ICD-10 codes can be used for glaucoma?

There are a lot of ICD-10 codes that you can use for glaucoma-related cases. Here are six among many that you can use:

1. H40.003

• This ICD-10 code stands for Preglaucoma, unspecified, bilateral. This is meant to be used on patients who have exhibited enough symptoms to show early signs of getting glaucoma. They don’t have glaucoma per se, but whatever signs were spotted during examinations point toward the patient developing one for both eyes, hence the bilateral.

• The unspecified in this context is that the type of glaucoma they have isn’t clear yet.

2. H40.009

• This ICD-10 code stands for Preglaucoma, unspecified, unspecified eye. This is exactly the same as the previous ICD-10 code. The particular glaucoma is not specified, meaning it isn’t known right now. The only difference is that whatever testing has been done hasn’t properly identified which eye the patient is at risk of developing glaucoma.

3. H40.10X0

• This ICD-10 code stands for Unspecified open-angle glaucoma, stage unspecified. This means that the patient is confirmed to have open-angle glaucoma, but two things are unclear: 1) what specific type of open-angle glaucoma the patient has, and 2) what stage the open-angle glaucoma is in (severity). This should only be used when both are unclear.

4. H40.1230

• This ICD-10 code stands for Low-tension glaucoma, bilateral, stage unspecified. This means the patient that this code is being used for is confirmed to have low-tension glaucoma in both of their eyes hence bilateral. The only thing that isn’t clear is what stage the low-tension glaucoma is.

5. H40.1330

• This ICD-10 code stands for Pigmentary glaucoma, bilateral, stage unspecified. This code is used when the patient is confirmed to have pigmentary glaucoma in both eyes. Like with the previous codes, the stage of the pigmentary glaucoma isn’t known, but once the severity is confirmed, a more specific ICD-10 code that mentions the severity should be used.

6. H40.823

• This ICD-10 code stands for Hypersecretion glaucoma, bilateral. This code is used once the patient is confirmed to have a hypersecretion type of glaucoma in both eyes, and the specific stage of the glaucoma hasn’t been determined.

Which of these Glaucoma codes are billable?

All of them are billable codes and can be used to designate a patient for reimbursement purposes.

Clinical information

Glaucoma is a group of eye conditions that damage the optic nerve. These types of eye conditions are not good because they don’t have any cures, and unfortunately, many types of glaucoma have no warning signs. People with glaucoma will sadly not notice that they have it until the condition has progressed far enough for vision changes to be noticeable. It’s also the leading cause of blindness for patients aged 60+.

Since there is no cure for glaucoma, the only thing you can do is try and detect signs as early as possible to manage it. The best things to do include: 1) going to an eye doctor for regular checkups, 2) taking prescribed eye drops, and 3) wearing eye protection.

Synonyms include:

• Angle closure glaucoma suspect
• Angle closure glaucoma suspect of bilateral eyes
• Angle closure glaucoma suspect of left eye
• Angle closure glaucoma suspect of right eye
• Glaucoma suspect caused by corticosteroid
• Glaucoma suspect of bilateral eyes caused by corticosteroid
• Glaucoma suspect of left eye caused by corticosteroid
• Glaucoma suspect of right eye caused by corticosteroid
