Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to N28.89: its own notes plus those printed at N28.8, block N25-N29, and Chapter 14. A note printed at a category, block or chapter applies to every code under it.
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

Clinical ClassificationClinical
AHRQ’s CCSR groups this code into broader clinical categories.
Clinical InformationClinical
Ureterocele
a cystic dilatation of the end of a ureter as it enters into the urinary bladder. it is characterized by the ballooning of the ureteral orifice into the lumen of the bladder and may obstruct urine flow.
Patient EducationClinical
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.

Questions About N28.89Overview
What is the ICD-10 code for other specified disorders of kidney and ureter?
The ICD-10-CM code for other specified disorders of kidney and ureter is N28.89 (sometimes written as N2889). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is N28.89 (Other specified disorders of kidney and ureter) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other specified disorders of kidney and ureter on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does N28.89 group to?
When other specified disorders of kidney and ureter is the principal diagnosis on an inpatient stay, it groups to MS-DRG 699, 698, 700, with relative weights from 0.6740 to 1.6400 depending on complications. Higher weights mean higher Medicare reimbursement.
Can N28.89 be reported with N13.4?
Not as a rule. The Excludes1 note at N28.8, which applies to N28.89, lists "hydroureter (N13.4)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
What is the ICD-9 equivalent of N28.89?
Under the General Equivalence Mappings, other specified disorders of kidney and ureter converts to ICD-9-CM 593.82 (ureteral fistula) and 593.89 (renal & ureteral dis NEC). The mapping is approximate, so confirm the match fits the documentation.
