What is the ICD-10 code for elevated eye pressure?

The ICD-10 code for elevated eye pressure without a glaucoma diagnosis is R03.0. For confirmed glaucoma, use codes within the H40 range, specifying type, laterality, and stage.

How do you code primary open-angle glaucoma?

Primary open-angle glaucoma is coded using H40.11X_, with the last digit indicating laterality and stage. Ensure documentation includes IOP, optic nerve findings, and visual fields.

Code	Description	When to Use	Key Documentation
H40.1111	Primary open-angle glaucoma, right eye, mild stage	Use when diagnosing mild primary open-angle glaucoma in the right eye with documented IOP and optic nerve changes.	IOP ≥22 mmHg Cup-to-disc ratio ≥0.6 Visual field defect
R03.0	Elevated blood pressure reading, without diagnosis of hypertension	Use for elevated IOP readings without confirmed glaucoma diagnosis.	Single elevated IOP reading ≥22 mmHg No optic nerve damage or visual field loss

Documentation & Coding Risks

Avoid these common issues when documenting Eye Pressure.

Failing to document laterality and stage

Impact

Clinical: Leads to incomplete clinical records., Regulatory: Increases risk of audit and non-compliance., Financial: May result in denied claims or reduced reimbursement.

Mitigation

Use templates that prompt for laterality and stage, Regular training on documentation standards

Using unspecified codes when specifics are available

Impact

Reimbursement: May result in reduced reimbursement due to lack of specificity., Compliance: Increases risk of audit due to non-specific coding., Data Quality: Leads to poor data quality and inaccurate clinical records.

Mitigation

Always document and code the specific type, laterality, and stage of glaucoma.

Specificity in glaucoma coding

Impact

Using unspecified codes increases audit risk.

Mitigation

Ensure documentation includes specific type, laterality, and stage.
