Primary ICD-10-CM Code for neovascular glaucoma

Glaucoma secondary to other eye disorders
Non-billable Code

Decision Criteria

clinical Criteria

  • Presence of neovascularization on gonioscopy

coding Criteria

  • Link to underlying condition like diabetic retinopathy

Applicable To

  • Neovascular glaucoma

Excludes

  • Primary open-angle glaucoma (H40.1-)
  • Primary angle-closure glaucoma (H40.2-)

Clinical Validation Requirements

  • Gonioscopy showing angle neovascularization
  • Fluorescein angiography for rubeosis
  • Elevated VEGF levels

Code-Specific Risks

  • Incorrectly using unspecified codes
  • Not linking to the underlying cause

Coding Notes

  • Ensure to document the specific underlying cause and the presence of neovascularization.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Ocular ischemia

H44.23-
Use if carotid artery disease is present.

Central retinal vein occlusion

H34.83
Use when CRVO is the underlying cause.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Other specified glaucoma

H40.89
Use when the neovascular component is unconfirmed or atypical.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Neovascular Glaucoma to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code H40.5X.

Impact

Clinical: May lead to inappropriate treatment plans., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims.

Mitigation Strategy

Use templates that prompt for etiology., Regular training on documentation standards.

Impact

Reimbursement: May lead to lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Poor data quality affecting patient records.

Mitigation Strategy

Use H40.5X with the underlying condition code.

Impact

Failure to document underlying conditions linked to neovascular glaucoma.

Mitigation Strategy

Use structured templates that include fields for etiology.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

Frequently Asked Questions

Common questions about ICD-10 coding for Neovascular Glaucoma, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for Neovascular Glaucoma

Use these documentation templates to ensure complete and accurate documentation for Neovascular Glaucoma. These templates include all required elements for proper coding and billing.

Ophthalmology Progress Note

Specialty: Ophthalmology

Required Elements

  • Assessment
  • Etiology
  • Stage
  • Diagnostics

Example Documentation

**Assessment**: Neovascular glaucoma (H40.5X) - Etiology: Proliferative diabetic retinopathy (E11.31) - Stage: Angle closure with IOP 48 mmHg (post-laser) - Diagnostics: Gonioscopy (Grade IV neovascularization), VEGF >500 pg/mL in aqueous

Examples: Poor vs. Good Documentation

Poor Documentation Example
Glaucoma with vascular changes
Good Documentation Example
360° angle neovascularization with synechial closure; history of CRVO confirmed by OCT angiography
Explanation
The good example specifies the type of glaucoma and links it to a documented underlying condition.
