Answer: Do not report 239.5 (Neoplasms of unspecified nature; other genitourinary organs) for a renal mass. A note in the ICD-9 manual dictates that "the term 'mass' unless otherwise stated is not to be regarded as a neoplastic growth." A mass such as a mass in the kidney may mean many things including a malignant or benign process abscess cyst or even a normal but hypertrophied portion of the kidney.

If "kidney mass" is the only information you have code 593.9 (Unspecified disorder of kidney and ureter) is the most appropriate diagnosis. If a radiological study of the kidney discovers a renal mass but there is no conclusive diagnosis you can also report 793.5 (Nonspecific abnormal findings on radiological and other examination of body structure; genitourinary organs).
