Understanding Chronic Kidney Disease Stage 3b (CKD Stage 3b) is crucial for accurate clinical documentation and medical coding. This resource provides information on moderate Chronic Kidney Disease, including diagnosis criteria, treatment options, and managing moderate to severe CKD. Learn about relevant healthcare guidelines for CKD 3b and ensure proper coding for optimal patient care.
Also known as
Chronic kidney disease, stage 3b
Moderate-to-severe decrease in kidney function.
Chronic kidney disease
Long-term progressive loss of kidney function.
Hypertensive diseases
High blood pressure, often a cause or complication of CKD.
Diabetes mellitus
A common cause of chronic kidney disease.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is the documented diagnosis CKD Stage 3b?
Yes
Is there documentation of cause?
No
Do not code as CKD Stage 3b. Review documentation for correct diagnosis.
When to use each related code

Insufficient documentation to support stage 3b, potentially leading to upcoding or downcoding. CDI query needed.
Coding risks related to hypertension, diabetes, other conditions commonly associated with CKD requiring specific documentation.
Unspecified documentation (e.g., 'moderate CKD') causing coding ambiguity impacting reimbursement and quality metrics.
Q: What are the key differential diagnoses to consider when a patient presents with an eGFR between 30-44 mL/min/1.73m2, indicating Chronic Kidney Disease Stage 3b?
A: While an eGFR between 30-44 mL/min/1.73m2 suggests Chronic Kidney Disease Stage 3b (CKD Stage 3b), it's crucial to consider other conditions that can mimic CKD Stage 3b presentation. These differential diagnoses may include acute kidney injury (AKI), urinary tract obstruction, certain medications impacting kidney function, and rare conditions like glomerulonephritis or polycystic kidney disease. A thorough patient history, including medication reconciliation, physical examination, and further laboratory and imaging studies (such as urine analysis, renal ultrasound, or kidney biopsy if indicated) are essential to distinguish CKD Stage 3b from these other potential causes. Explore how incorporating a structured diagnostic approach can improve accuracy in identifying the underlying cause of reduced kidney function.
Q: How should clinicians manage hypertension in patients with CKD Stage 3b to delay progression to Stage 4 and cardiovascular complications?
A: Hypertension management in Chronic Kidney Disease Stage 3b (CKD Stage 3b) is paramount to slow disease progression and minimize cardiovascular risks. Clinicians should aim for a blood pressure target of less than 130/80 mmHg, as recommended by current guidelines. First-line antihypertensive agents for CKD Stage 3b often include ACE inhibitors or ARBs due to their renoprotective effects, even in the absence of proteinuria. However, careful monitoring of potassium levels and kidney function is crucial. Other suitable options may include calcium channel blockers and thiazide diuretics. Consider implementing regular blood pressure monitoring and patient education about lifestyle modifications, including dietary sodium restriction and regular exercise, to optimize hypertension control and improve patient outcomes.

Patient presents with chronic kidney disease stage 3b (CKD stage 3b), also known as moderate chronic kidney disease or moderate to severe CKD. The diagnosis is based on an estimated glomerular filtration rate (eGFR) between 30 and 44 mL/min/1.73m2, confirmed on two separate occasions at least 90 days apart. Patient's current eGFR is [insert value] mL/min/1.73m2, calculated using the [specify equation used, e.g., CKD-EPI creatinine equation]. Relevant laboratory findings include [list serum creatinine, BUN, urine albumin-to-creatinine ratio (ACR), and other pertinent lab values]. Clinical manifestations may include [document any present signs or symptoms such as fatigue, swelling, changes in urination, or hypertension]. Comorbidities contributing to CKD progression include [list comorbidities, e.g., diabetes, hypertension, cardiovascular disease]. Assessment includes evaluation for complications of CKD such as anemia, mineral and bone disorders, and cardiovascular disease. Plan of care includes management of underlying conditions, blood pressure control with [specify medication class, e.g., ACE inhibitors, ARBs], monitoring of kidney function with regular eGFR and urine ACR measurements, and patient education regarding renal diet, fluid management, and medication adherence. Referral to nephrology is recommended for ongoing management and evaluation for renal replacement therapy in the future. ICD-10 code N18.4 is used for chronic kidney disease stage 3b. This documentation supports medical necessity for prescribed medications, laboratory tests, and specialist referrals.
