2025 ICD-10-CM code N18.3
(Active) Effective Date: N/A Revision Date: N/A Diseases of the genitourinary system - Chronic kidney disease XIV Diseases of the genitourinary system Feed
Chronic kidney disease, stage 3 (moderate).
Medical necessity for coding N18.3 is established through documentation supporting the diagnosis of stage 3 chronic kidney disease, based on clinical findings, GFR calculation, and other relevant tests.The documentation must demonstrate the presence of kidney damage or reduced kidney function for at least 3 months.
Diagnosis and management of chronic kidney disease. This involves evaluating kidney function through GFR calculation, urinalysis for albuminuria, and other relevant tests. Monitoring disease progression, managing complications such as hypertension, anemia and electrolyte imbalances, and providing patient education and counseling are also part of the clinical responsibility.
In simple words: This code describes a moderate level of chronic kidney disease.Chronic kidney disease means the kidneys aren't working as well as they should over a long period. Stage 3 means the kidney damage is moderate. A doctor uses this code after tests show that your kidneys aren't filtering waste from your blood as effectively as they should.
This ICD-10-CM code classifies chronic kidney disease (CKD) at stage 3, indicating moderate severity.It reflects a sustained decrease in glomerular filtration rate (GFR) and/or evidence of kidney damage for at least three months.Specific criteria for diagnosis include GFR levels and/or presence of albuminuria, along with other clinical findings.Code first any associated conditions, such as diabetic or hypertensive CKD.Use additional codes as needed to specify kidney transplant status.
Example 1: A 55-year-old male with type 2 diabetes presents with persistent proteinuria and reduced GFR, consistent with stage 3 CKD. The physician orders additional tests to confirm the diagnosis and initiate disease management strategies., A 60-year-old female with a history of hypertension is found to have a reduced GFR on routine blood tests.Further evaluation reveals stage 3 CKD.The physician starts treatment to control blood pressure and discusses lifestyle changes, along with potential future interventions., A 70-year-old patient with a history of long-standing kidney disease undergoes regular monitoring.Their most recent GFR indicates progression to stage 3 CKD, prompting adjustments in medication and increased frequency of follow-up appointments.
Complete medical history, including relevant risk factors (diabetes, hypertension, family history);Results of blood tests (GFR, serum creatinine, electrolytes); Urinalysis, including protein/creatinine ratio;Imaging studies (ultrasound, CT scan) if indicated;Physician's assessment of kidney function and disease stage;Documentation of treatment plan and patient education.
** This code is used for billing purposes to represent the diagnosis of chronic kidney disease, stage 3 (moderate).Accurate documentation is crucial for appropriate reimbursement.
