Acute cystitis is an acute inflammation of the urinary bladder, usually caused by bacterial infection.
Modifiers may be applicable depending on the circumstances of the encounter, such as the place of service or type of visit. Consult the current modifier guidelines for appropriate use.
Medical necessity for coding N30.0 is established by the presence of clinical symptoms and laboratory findings consistent with acute cystitis.This includes evidence of bladder infection, such as pyuria and bacteriuria on urinalysis and possibly a positive urine culture identifying a causative pathogen.Treatment with antibiotics is medically necessary to resolve the infection and prevent complications.
Diagnosis and treatment of acute cystitis typically falls under the responsibility of a urologist or primary care physician.The physician's duties include obtaining a thorough patient history, performing a physical examination, ordering and interpreting diagnostic tests (urinalysis, urine culture), prescribing and monitoring antibiotic therapy, and educating the patient on preventive measures.
In simple words: Acute cystitis, or a bladder infection, is an inflammation of the bladder often caused by bacteria.Symptoms include frequent urination, painful urination, fever, cloudy or bloody urine, and pain above the pubic bone.It's usually treated with antibiotics.
Acute cystitis is an acute infection and inflammation of the urinary bladder.It is most commonly caused by bacterial infection, leading to symptoms such as increased urinary frequency, pain or burning during urination (dysuria), fever, cloudy or bloody urine, and suprapubic pain (pain above the pubic bone).The diagnosis is typically made through urinalysis and possibly urine culture to identify the causative bacteria. Treatment usually involves antibiotics tailored to the specific pathogen.
Example 1: A 25-year-old female presents with urgency, frequency, and dysuria. Urinalysis reveals pyuria and bacteriuria.N30.0 is coded., A 68-year-old male with a history of benign prostatic hyperplasia (BPH) reports similar symptoms.A urine culture identifies *E. coli*. N30.0 is coded along with a code for BPH. , A 12-year-old girl experiences suprapubic pain and cloudy urine after recent sexual abuse.A urine culture is positive for *Staphylococcus saprophyticus*.N30.0 is coded, potentially with additional codes for sexual assault and the identified pathogen. The healthcare professional must take appropriate steps to document and report child sexual abuse.
Complete history and physical examination documenting symptoms (urgency, frequency, dysuria, suprapubic pain); results of urinalysis (pyuria, hematuria, bacteriuria); urine culture with identification of pathogen (if performed); treatment plan (antibiotics, pain management); and response to treatment.If the patient presents with symptoms suggestive of a sexually transmitted infection, documentation to support this diagnosis is crucial.
** This code should be used for acute cystitis.Chronic cystitis is coded differently (N30.1, N30.2, N30.8).
