2022 ICD-10-CM Code N10
Acute pyelonephritis
Valid for Submission
ICD-10: | N10 |
Short Description: | Acute pyelonephritis |
Long Description: | Acute pyelonephritis |
Code Classification
N10 is a billable diagnosis code used to specify a medical diagnosis of acute pyelonephritis. The code N10 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 N10 might also be used to specify conditions or terms like acute bacterial tubulointerstitial nephritis, acute fungal tubulointerstitial nephritis, acute infectious tubulointerstitial nephritis, acute nephritis due to another disorder, acute on chronic tubulointerstitial nephritis , acute pyelitis, etc.
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 N10:
Inclusion Terms
Inclusion TermsThese 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.
- Acute infectious interstitial nephritis
- Acute pyelitis
- Acute tubulo-interstitial nephritis
- Hemoglobin nephrosis
- Myoglobin nephrosis
Use Additional Code
Use Additional CodeThe “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
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 N10 are found in the index:
- - Nephritis, nephritic (albuminuric) (azotemic) (congenital) (disseminated) (epithelial) (familial) (focal) (granulomatous) (hemorrhagic) (infantile) (nonsuppurative, excretory) (uremic) - N05.9
- - tubulo-interstitial (in) - N12
- - acute (infectious) - N10
- - tubulo-interstitial (in) - N12
- - Nephrosis, nephrotic (Epstein's) (syndrome) (congenital) - N04.9
- - hemoglobin - N10
- - myoglobin - N10
- - Pyelitis (congenital) (uremic) - See Also: Pyelonephritis;
- - acute - N10
- - Pyelonephritis - See Also: Nephritis, tubulo-interstitial;
- - acute - N10

Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code N10 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
MS-DRG | MS-DRG Title | MCD | Relative Weight |
---|---|---|---|
689 | KIDNEY AND URINARY TRACT INFECTIONS WITH MCC | 11 | 1.1113 |
690 | KIDNEY AND URINARY TRACT INFECTIONS WITHOUT MCC | 11 | 0.7922 |
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 N10 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code N10 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
Kidney Diseases
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
- Cancer
- Cysts
- Stones
- Infections
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.
