Understand Low Glomerular Filtration Rate (GFR) diagnosis, staging, and clinical implications. Learn about GFR blood test, creatinine levels, Chronic Kidney Disease (CKD) stages, and medical coding for accurate healthcare documentation. Explore resources for diagnosis, treatment, and management of Low GFR and related renal conditions. Find information on eGFR calculation, normal GFR range, and clinical documentation best practices for optimal patient care.
Also known as
Chronic kidney disease
Covers stages 1-5 of chronic kidney disease based on GFR.
Hypertensive chronic kidney disease
Chronic kidney disease with hypertension as a contributing factor.
Chronic kidney disease with other heart disease
Chronic kidney disease complicated by heart conditions excluding hypertension.
Unspecified anuria/oliguria
Reduced urine output which can be a sign of decreased kidney function.

Is CKD documented?
When to use each related code
| Description |
|---|
| Low GFR (eGFR <60) |
| Chronic Kidney Disease |
| Acute Kidney Injury |
Coding CKD without specifying stage (e.g., N18.9) when clinical data supports a specific stage (e.g., N18.3) leads to inaccurate severity reflection and reimbursement.
Incorrectly coding conditions like hypertension (I10) or diabetes (E11.22) as causing CKD when they are coexisting, impacting risk adjustment and quality metrics.
Miscoding acute kidney injury (AKI, N17) as chronic kidney disease (CKD, N18) or vice versa based on imprecise documentation, skewing prevalence data and treatment plans.
Patient presents with signs and symptoms suggestive of chronic kidney disease (CKD) secondary to low glomerular filtration rate (GFR). Presenting complaints include fatigue, generalized weakness, and recent changes in urination frequency. Patient denies dysuria, hematuria, or flank pain. Relevant medical history includes hypertension, controlled with lisinopril, and type 2 diabetes mellitus, managed with metformin. Physical examination reveals stable vital signs and no overt edema. Laboratory results demonstrate a GFR of 45 mLmin1.73 m2, confirming stage 3A chronic kidney disease. Urinalysis shows microalbuminuria. Serum creatinine and blood urea nitrogen (BUN) are elevated. Diagnosis of low GFR and CKD stage 3A is established based on the National Kidney Foundation guidelines. Plan includes optimization of blood pressure control, strict glycemic management, and dietary counseling focusing on protein restriction and phosphorus control. Patient education regarding renal diet, medication adherence, and the importance of regular nephrology follow-up was provided. Referral to a registered dietitian and nephrologist is scheduled. Monitoring of GFR, creatinine, BUN, and urine protein will be performed at regular intervals to assess disease progression and response to treatment. Potential complications of CKD, including cardiovascular disease and mineral bone disorder, were discussed with the patient.
