Prostate
A gland in males that surrounds the neck of the URINARY BLADDER and the URETHRA. It secretes a substance that liquefies coagulated semen. It is situated in the pelvic cavity behind the lower part of the PUBIC SYMPHYSIS, above the deep layer of the triangular ligament, and rests upon the RECTUM.
Prostatitis
Infiltration of inflammatory cells into the parenchyma of PROSTATE. The subtypes are classified by their varied laboratory analysis, clinical presentation and response to treatment.
About the N41 Code Range
This section covers **ICD-10 codes for inflammatory diseases of the prostate**, ranging from acute and chronic prostatitis to abscesses and other specific prostate inflammations. These codes help identify and categorize various prostate infections and inflammatory conditions for accurate diagnosis and treatment documentation.
The **ICD-10 code N41** encompasses all inflammatory diseases of the prostate. More specific codes include **N41.0 for acute prostatitis**, often called bacterial prostatitis or prostatitis category I, which refers to sudden prostate inflammation caused by infection. **N41.1 covers chronic prostatitis**, known by several names such as chronic pelvic pain syndrome or prostatitis categories II and III, capturing long-term prostate inflammation that may or may not be bacterial. An abscess of the prostate is coded as **N41.2**, detailing fluid collections from severe infections. Other forms include **N41.3 prostatocystitis, N41.4 granulomatous prostatitis**, and **N41.8 for other less common or fungal-related inflammations** such as blastomycosis or non-bacterial prostatitis. When the inflammation lacks clear specifics, the code **N41.9** is used for unspecified cases, including asymptomatic or chlamydial prostatitis. This classification system allows precise identification of prostate inflammatory conditions for healthcare providers and medical coders searching for the correct ICD-10 code for prostate inflammation.
