Code Classification

  • Diseases of the genitourinary system
    (N00–N99)
    • Urolithiasis
      (N20-N23)
      • Unspecified renal colic
        (N23)

N23 is a billable diagnosis code used to specify a medical diagnosis of unspecified renal colic. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like N23 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Patient Education


Kidney Stones

A kidney stone is a solid piece of material that forms in the kidney from substances in the urine. It may be as small as a grain of sand or as large as a pearl. Most kidney stones pass out of the body without help from a doctor. But sometimes a stone will not go away. It may get stuck in the urinary tract, block the flow of urine and cause great pain.

The following may be signs of kidney stones that need a doctor's help:

  • Extreme pain in your back or side that will not go away
  • Blood in your urine
  • Fever and chills
  • Vomiting
  • Urine that smells bad or looks cloudy
  • A burning feeling when you urinate

Your doctor will diagnose a kidney stone with urine, blood, and imaging tests.

If you have a stone that won't pass on its own, you may need treatment. It can be done with shock waves; with a scope inserted through the tube that carries urine out of the body, called the urethra; or with surgery.

Pelvic Pain

Pelvic pain occurs mostly in the lower abdomen area. The pain might be steady, or it might come and go. It can be a sharp and stabbing pain in a specific spot, or a dull pain that is spread out. If the pain is severe, it might get in the way of your daily activities.

If you're a woman, you might feel pain during your period. It could also happen when you have sex. Pelvic pain can be a sign that there is a problem with one of the organs in your pelvic area, such as the uterus, ovaries, fallopian tubes, cervix, or vagina. If you're a man, the cause could be problem with the prostate. In men and women, it could be a symptom of infection, or a problem with the urinary tract, lower intestines, rectum, muscle, or bone. Some women have more than one cause of pelvic pain at the same time.

You might have to have lab, imaging, or other medical tests to find the cause of the pain. The treatment will depend on the cause, how bad the pain is, and how often it occurs.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
