What is the ICD-10 code for glomerulonephritis?

The ICD-10 code for acute nephritic syndrome with diffuse membranous glomerulonephritis is N00.2. Ensure to document specific histological findings for accurate coding.

How to code primary membranous nephropathy?

Use ICD-10 code N04.21 for primary membranous nephropathy, ensuring negative PLA2R antibody testing is documented.

Documentation & Coding Risks

Avoid these common issues when documenting Glomerulonephritis.

Vague documentation of kidney inflammation.

Impact

Clinical: Leads to misdiagnosis and inappropriate treatment., Regulatory: Increases risk of non-compliance with coding standards., Financial: Potential for reduced reimbursement due to unspecified coding.

Mitigation

Use specific medical terminology, Ensure biopsy results are documented

Using unspecified codes when specific histology is available.

Impact

Reimbursement: May result in lower DRG assignment and reimbursement., Compliance: Increases risk of audit and non-compliance., Data Quality: Decreases accuracy of clinical data.

Mitigation

Always use specific codes when biopsy results provide detailed histological findings.

Incorrect principal diagnosis coding

Impact

Using unspecified codes when specific diagnosis is available.

Mitigation

Ensure detailed documentation and use of specific codes.
