Malig neoplasm of unsp testis, unsp descended or undescended

This code signifies a cancerous tumor originating in the testis, where the specific side (left or right) is not documented. It also indicates that the documentation does not specify whether the affected testis was descended into the scrotum or remained undescended. This diagnosis implies a primary malignancy of testicular tissue.

Use this code when medical record documentation confirms a malignant neoplasm of the testis, but lacks specificity regarding laterality (left or right) and the testicular position (descended or undescended). This code is appropriate when the physician's notes simply state "testicular cancer" without further anatomical detail.

• Avoid using this code if laterality (left or right testis) or descent status is documented; instead, choose a more specific code from the C62 series.
• Always query the provider for clarification on laterality and descent if possible, to allow for more precise coding.
• This code is a "NOS" (Not Otherwise Specified) code, indicating a lack of detailed information in the medical record.
