How do you code chronic kidney disease with hypertension?

Code I12.9 for hypertensive CKD followed by the specific CKD stage code, such as N18.4 for stage 4.

What is the ICD-10 code for end-stage renal disease?

The ICD-10 code for end-stage renal disease is N18.6, used when eGFR is <15 or the patient is on dialysis.

Compare key differences between these codes to ensure accurate selection

Code	Description	When to Use	Key Documentation
N18.1	Chronic kidney disease, stage 1	Use when eGFR is ≥90 and there is evidence of kidney damage.	eGFR ≥90 Proteinuria or other markers of kidney damage
N18.4	Chronic kidney disease, stage 4	Use when eGFR is between 15 and 29.	eGFR 15-29
N18.6	End-stage renal disease	Use when eGFR is <15 or patient is on dialysis.	eGFR <15 or dialysis dependence

Documentation & Coding Risks

Avoid these common issues when documenting Chronic Kidney Injury.

Failing to link CKD to hypertension or diabetes

Impact

Clinical: May lead to incomplete treatment plans., Regulatory: Increases risk of coding audits., Financial: Potential loss of reimbursement for related conditions.

Mitigation

Always assess and document underlying conditions, Use appropriate combination codes

Using unspecified CKD codes

Impact

Reimbursement: May result in lower reimbursement rates., Compliance: Increases risk of audits., Data Quality: Leads to poor data quality and inaccurate patient records.

Mitigation

Always document and code the specific CKD stage.

Unspecified CKD coding

Impact

Using unspecified codes when specific stages are documented.

Mitigation

Ensure eGFR and CKD stage are documented in every patient encounter.
