Valid for Submission
N04.1 is a billable diagnosis code used to specify a medical diagnosis of nephrotic syndrome with focal and segmental glomerular lesions. The code N04.1 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code N04.1 might also be used to specify conditions or terms like classical focal segmental glomerulosclerosis, congenital nephrotic syndrome with focal glomerulosclerosis, focal segmental glomerulosclerosis, hyperfiltration focal segmental glomerulosclerosis or nephrotic syndrome, focal and segmental glomerular lesions.
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code N04.1:
Inclusion TermsInclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Nephrotic syndrome with focal and segmental hyalinosis
- Nephrotic syndrome with focal and segmental sclerosis
- Nephrotic syndrome with focal glomerulonephritis
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code N04.1 are found in the index:
- - Nephrosis, nephrotic (Epstein's) (syndrome) (congenital) - N04.9
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Classical focal segmental glomerulosclerosis
- Congenital nephrotic syndrome with focal glomerulosclerosis
- Focal segmental glomerulosclerosis
- Hyperfiltration focal segmental glomerulosclerosis
- Nephrotic syndrome, focal and segmental glomerular lesions
Diagnostic Related Groups - MS-DRG Mapping
|MS-DRG||MS-DRG Title||MCD||Relative Weight|
|698||OTHER KIDNEY AND URINARY TRACT DIAGNOSES WITH MCC||11||1.6067|
|699||OTHER KIDNEY AND URINARY TRACT DIAGNOSES WITH CC||11||1.0252|
|700||OTHER KIDNEY AND URINARY TRACT DIAGNOSES WITHOUT CC/MCC||11||0.7448|
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert N04.1 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code N04.1 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
You have two kidneys, each about the size of your fist. They are near the middle of your back, just below the rib cage. Inside each kidney there are about a million tiny structures called nephrons. They filter your blood. They remove wastes and extra water, which become urine. The urine flows through tubes called ureters. It goes to your bladder, which stores the urine until you go to the bathroom.
Most kidney diseases attack the nephrons. This damage may leave kidneys unable to remove wastes. Causes can include genetic problems, injuries, or medicines. You have a higher risk of kidney disease if you have diabetes, high blood pressure, or a close family member with kidney disease. Chronic kidney disease damages the nephrons slowly over several years. Other kidney problems include
Your doctor can do blood and urine tests to check if you have kidney disease. If your kidneys fail, you will need dialysis or a kidney transplant.
