Prostate cancer occurs when a group is found abnormal cells in the prostate. First, the cells will be limited to the gland, but may eventually spread or metastasize to other areas. There is a better prognosis if the cancer is detected early while still confined to the prostate.
Prostate cancer is coded according to the International Classification of Disease (ICD). The current version is ICD-9. ICD-10 comes into effect in the USA October 2013, whilst ICD-11 is in progress and will be completed in 2015. ICD was first adopted in France back in 1893 and the ICD-9 was adopted in 1979 by the World Health Association.
The codes are used by medical coders to classify diseases into categories. However, physicians will use alternative databases such as SNOMED CT (Systematized Nomenclature of Medicine Clinical Terms) developed by the IHTSDO, which includes 18 countries.
Prostate Cancer ICD-9 Code (and ICD-10)
For some aspects of prostate disease there is a direct match between ICD-9 and ICD-10. For instance, the code for primary prostate cancer in ICD-9 is 185, while the ICD-10 code is C61.
Prostate intraepithelial neoplasia (PIN) is a pre-cancerous stage also included in the ICD classification. Stages 1 and 2 are classed as ICD-9 code 602.3, while stage 3 is ICD-9 code 233.4 for carcinoma in situ (early, local cancer) of the prostate.
Treatments are also recorded in the ICD classification. For instance, prostatectomy surgery is 60.21 to 60.69, chemotherapy is 99.25, external beam radiotherapy is 92.29, hormonal therapy is 99.24 and brachytherapy is 92.27.
ICD-9 codes for malignant prostate cancer outside the prostate include bony metastases (198.5), bladder or urethral metastases (198.1), pelvic lymph nodes (196.6) and seminal vesicles (198.82).
