N30.4 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of irradiation cystitis. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Irradiation cystitis

Non-specific codes like N30.4 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for irradiation cystitis:

  • Use N30.40 for Irradiation cystitis without hematuria - BILLABLE CODE

  • Use N30.41 for Irradiation cystitis with hematuria - BILLABLE CODE

Clinical Information

  • Cystitis

    inflammation of the urinary bladder, either from bacterial or non-bacterial causes. cystitis is usually associated with painful urination (dysuria), increased frequency, urgency, and suprapubic pain.
  • Cystitis, Interstitial

    a condition with recurring discomfort or pain in the urinary bladder and the surrounding pelvic region without an identifiable disease. severity of pain in interstitial cystitis varies greatly and often is accompanied by increased urination frequency and urgency.
  • Urinary Bladder

Patient Education


Bladder Diseases

The bladder is a hollow organ in your lower abdomen that stores urine. Many conditions can affect your bladder. Some common ones are:

  • Cystitis - inflammation of the bladder, often from an infection
  • Urinary incontinence - loss of bladder control
  • Overactive bladder - a condition in which the bladder squeezes urine out at the wrong time
  • Interstitial cystitis - a chronic problem that causes bladder pain and frequent, urgent urination
  • Bladder cancer

Doctors diagnose bladder diseases using different tests. These include urine tests, x-rays, and an examination of the bladder wall with a scope called a cystoscope. Treatment depends on the cause of the problem. It may include medicines and, in severe cases, surgery.

Radiation Therapy

Radiation therapy is a cancer treatment. It uses high doses of radiation to kill cancer cells and stop them from spreading. About half of all cancer patients receive it. The radiation may be external, from special machines, or internal, from radioactive substances that a doctor places inside your body. The type of radiation therapy you receive depends on many factors, including:

  • The type of cancer
  • The size of the cancer
  • The cancer's location in the body
  • How close the cancer is to normal tissues that are sensitive to radiation
  • How far into the body the radiation needs to travel
  • Your general health and medical history
  • Whether you will have other types of cancer treatment
  • Other factors, such as your age and other medical conditions

Radiation therapy can damage normal cells as well as cancer cells. Treatment must be carefully planned to minimize side effects. Common side effects include skin changes and fatigue. Other side effects depend on the part of your body being treated.

Sometimes radiation is used with other treatments, like surgery or chemotherapy.
