Ob-Gyn Coding Alert

You’ll need to signify whether patient has hematuria. 

Interstitial cystitis is a long-term or chronic inflammation of the bladder wall. Physicians usually diagnose this condition by ruling out other conditions (such as sexually transmitted disease, bladder cancer, and bladder infections). 

Currently, you should report this condition with 595.1 (Chronic interstitial cystitis).

ICD-10-CM: When your diagnosis coding changes, you will have two new diagnoses. They are:

• N30.10, Interstitial cystitis (chronic) without hematuria
• N30.11, Interstitial cystitis (chronic) with hematuria

You’ll choose between N30.10 and N30.11 based on whether the patient has hematuria. Hematuria is the presence of red blood cells in the urine. 

Documentation: Your physician will diagnose with interstitial cystitis after ruling out various conditions. Also, you may code an interstitial cystitis code when the provider documents “Hunner’s ulcer,” “panmural fibrosis of bladder,” or “submucous cystitis.”

Here’s how to find your codes in the Alphabetic Index:

Cystitis (exudative) (hemorrhagic) (septic) (suppurative) N30.90

- chronic N30.20
- - interstitial N30.10
- - - with hematuria N30.11

Coding tips: Under the notes for the category N30 (Cystitis), you’ll see “use additional code to identify infectious agent (B95-B97).” That means you should include a secondary diagnosis for the bacteria or virus that is causing the cystitis if it is known. Also an Excludes1 note lists prostatocystitis (N41.3). That means do not code N41.3 with either of these diagnoses (N30.10 or N30.11).
