Code Classification

Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified
(R00–R99)
- Abnormal findings on examination of urine, without diagnosis
  (R80-R82)
  - Other and unspecified abnormal findings in urine
    (R82)

R82.89 is a billable diagnosis code used to specify a medical diagnosis of other abnormal findings on cytological and histological examination of urine. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

According to ICD-10-CM guidelines this code should not to be used as a principal diagnosis code when a related definitive diagnosis has been established.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

High-grade urothelial carcinoma found on urine cytology
Low-grade urothelial neoplasia found on urine cytology
Podocyturia
Suspected high-grade urothelial carcinoma found on urine cytology
Suspected urological cancer
Suspected urothelial cancer
Urine cytology

Urine cytology
Urine cytology abnormal
Urine cytology borderline
Urine microscopy epithelial cells present
Urine microscopy: presence of cells - finding
Urine microscopy:RBC's present

R82.89 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
695	KIDNEY AND URINARY TRACT SIGNS AND SYMPTOMS WITH MCC	11	1.196
696	KIDNEY AND URINARY TRACT SIGNS AND SYMPTOMS WITHOUT MCC	11	0.6921

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.

Replacement Code

R8289 replaces the following previously assigned ICD-10-CM code(s):

R82.8 - Abnormal findings on cytolog and histolog exam of urine

Patient Education

Urinalysis

A urinalysis is a test of your urine. It is often done to check for a urinary tract infections, kidney problems, or diabetes. You may also have one during a checkup, if you are admitted to the hospital, before you have surgery, or if you are pregnant. It can also monitor some medical conditions and treatments.

A urinalysis involves checking the urine for:

Its color
Its appearance (whether it is clear or cloudy)
Any odor
The pH level (acidity)
Whether there are substances that are not normally in urine, such as blood, too much protein, glucose, ketones, and bilirubin
Whether there are cells, crystals, and casts (tube-shaped proteins)
Whether it contains bacteria or other germs

Urine and Urination

Your kidneys make urine by filtering wastes and extra water from your blood. The waste is called urea. Your blood carries it to the kidneys. From the kidneys, urine travels down two thin tubes called ureters to the bladder. The bladder stores urine until you are ready to urinate. It swells into a round shape when it is full and gets smaller when empty. If your urinary system is healthy, your bladder can hold up to 16 ounces (2 cups) of urine comfortably for 2 to 5 hours.

You may have problems with urination if you have:

Kidney failure
Urinary tract infections
An enlarged prostate
Bladder control problems like incontinence, overactive bladder, or interstitial cystitis
A blockage that prevents you from emptying your bladder

Some conditions may also cause you to have blood or protein in your urine. If you have a urinary problem, see your health care provider. Urinalysis and other urine tests can help to diagnose the problem. Treatment depends on the cause.
