What is the ICD-10 code for suspected glaucoma?

The ICD-10 code for suspected glaucoma varies based on specific findings, such as H40.01 for low-risk open-angle glaucoma suspect.

How do you document suspected glaucoma?

Document suspected glaucoma by including IOP measurements, optic nerve assessments, and any risk factors such as family history or diabetes.

Code	Description	When to Use	Key Documentation
H40.00	Unspecified pre-glaucoma	Use when no specific findings or risk factors are documented.	General suspicion of glaucoma without documented risk factors
H40.01	Open-angle with borderline findings, low risk	Use when there are borderline findings with low risk factors.	Elevated IOP or suspicious optic nerve 1-2 risk factors such as age >60 or African ancestry
H40.02	Open-angle with borderline findings, high risk	Use when there are borderline findings with high risk factors.	Elevated IOP and optic nerve changes ≥3 risk factors such as diabetes family history or thin cornea
H40.05	Ocular hypertension	Use when IOP is elevated but without optic nerve or visual field changes.	IOP >21 mmHg in ≥2 readings

Documentation & Coding Risks

Avoid these common issues when documenting Suspected Glaucoma.

Not documenting risk factors

Impact

Clinical: Inaccurate risk assessment., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials.

Mitigation

Ensure all risk factors are documented in the patient's record.

Using H40.0 instead of specific codes

Impact

Reimbursement: Claims may be denied due to lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Poor data quality and inaccurate patient records.

Mitigation

Use specific codes like H40.01 or H40.02 based on documented findings.

Specificity in coding

Impact

Using non-specific codes can trigger audits.

Mitigation

Ensure documentation supports the specific code used.
