2025 ICD-10-CM code N30

Cystitis: Inflammation of the urinary bladder.

Appropriate ICD-10 code selection depends on the specific type and severity of cystitis.Always specify the type of cystitis if possible (e.g., acute, chronic, interstitial) and code any associated infectious agents separately.

ICD-10 codes do not use modifiers.

Medical necessity for treatment of cystitis is established by the presence of symptoms consistent with a bladder infection and confirmation through urinalysis and/or urine culture. Treatment is necessary to alleviate symptoms and prevent complications.

Diagnosis and management of cystitis, including ordering of urinalysis and urine culture, prescribing antibiotics (if bacterial infection), and providing patient education on prevention and management.

IMPORTANT:Additional codes may be required to specify the type of cystitis (e.g., N30.0 for acute cystitis, N30.1 for interstitial cystitis, etc.) and any associated conditions or infectious agents (e.g., using codes from categories B95-B97).

In simple words: Cystitis is a bladder infection that causes pain when you pee, a frequent urge to pee, and pain above your pubic bone.It can be caused by bacteria or other things. Your doctor might need more information to give you the most accurate diagnosis.

Cystitis is an inflammation of the urinary bladder, which can be caused by bacterial or non-bacterial factors.It is characterized by symptoms such as painful urination (dysuria), increased urinary frequency and urgency, and suprapubic pain.Additional codes may be necessary to specify the infectious agent (if applicable) and any associated complications.N30 is a broad code and may require further specification depending on the clinical presentation (e.g., acute, chronic, interstitial, etc.).

Example 1: A 25-year-old female presents with symptoms of dysuria, frequency, and urgency. Urinalysis reveals a bacterial infection.The diagnosis is acute cystitis, coded as N30.0., A 50-year-old female with a history of interstitial cystitis reports worsening pelvic pain and urinary frequency.She has no hematuria. The diagnosis is interstitial cystitis without hematuria, coded as N30.10., A 70-year-old male with a history of radiation therapy for prostate cancer develops symptoms of cystitis. The diagnosis is irradiation cystitis, coded as N30.4.

Complete history and physical examination, urinalysis, urine culture (if indicated), and any relevant imaging studies (e.g., ultrasound).
