ICD Code N30.90

ICD code N30.90 is used to classify a diagnosis of cystitis, which is an inflammation of the bladder, without the presence of hematuria, meaning there is no blood in the urine. This code is utilized when the specific cause of the cystitis is not identified or specified in the patient's medical records.

When considering the use of the ICD code for cystitis, unspecified without hematuria, healthcare providers should evaluate the following diagnostic criteria and symptoms:

1. Presence of Urinary Symptoms: The patient exhibits symptoms such as frequent urination, urgency, dysuria (painful urination), or suprapubic discomfort.

2. Absence of Hematuria: There is no presence of blood in the urine, either visible or detected through urinalysis.

3. Exclusion of Specific Causes: The condition cannot be attributed to a specific cause such as bacterial infection, interstitial cystitis, or other identifiable urological conditions.

4. Negative Urine Culture: If a urine culture is performed, it may not show significant bacterial growth, suggesting a non-bacterial origin or an unspecified cause.

5. Patient History: The patient's medical history does not indicate a chronic condition or previous diagnosis that could explain the symptoms.

6. Physical Examination: A physical examination does not reveal any abnormalities that could point to a more specific diagnosis.

7. Lack of Systemic Symptoms: The patient does not exhibit systemic symptoms such as fever or chills, which could indicate a more severe infection or condition.

8. Response to Initial Treatment: The symptoms may improve with general measures such as increased fluid intake or symptomatic treatment, without the need for targeted antibiotic therapy.

By carefully assessing these criteria, healthcare providers can determine the appropriate use of the ICD code for cystitis, unspecified without hematuria, ensuring accurate documentation and effective management of the patient's condition.
