Understanding Testicular Cancer Coding: A Guide for Cancer Registrars
Coding the primary site is crucial in the field of cancer registration, as it ensures that data is reliable and useful for research and treatment planning.
One area that often presents challenges is the coding of testicular cancer. This article aims to clarify the proper use of site codes for testicular cancer, with a focus on the overused site code C629 (Testis, NOS).
Coding Primary Site
When coding the primary site for testicular cancer, it is important to distinguish between descended and undescended testis. The following codes should be used:
C620 - Undescended testis: This code is used for cases where the testis has not descended into the scrotum. Cryptorchidism, or undescended testis, is a condition that may require surgical intervention if spontaneous descent does not occur within the first few months of life. Tumors in undescended testis are uncommon but pose a known risk, especially if correction was delayed.
C621 - Descended testis: This code is used for cases where the testis is descended. Typical symptoms for coding a descended testis include a palpable lump, pain in the groin or lower abdomen, or imaging evidence of a mass.
C629 - Testis, NOS (Not Otherwise Specified): This code should be used sparingly. When a testicular mass is detectable by physical exam or ultrasound, it confirms a descended testis and should be coded as C621.
Presenting Symptoms – Descended Testis (Code C621)
For a descended testis, the following symptoms are indicative:
A lump or mass that can be felt in the testicle
Pain in the groin or lower abdomen
Imaging (ultrasound or scan) that shows a testicular mass
Physical exam or doctor’s note indicating a testicular mass (e.g., "Patient presents with a right testicular mass.")
Undescended Testis (Cryptorchidism)
Cryptorchidism refers to a condition in which one or both testicles fail to descend into the scrotum before birth. While spontaneous descent may occur within the first few months of life, surgical intervention (orchiopexy) is often required if descent does not occur. Tumors in undescended testis are uncommon but are a known risk, especially if correction was delayed.
Summary
In summary, site code C629 (Testis, NOS) should be used sparingly, as it is often overapplied. When a testicular mass is detectable by physical exam or ultrasound, it confirms a descended testis and should be coded as C621. Code C620 is for undescended testis. Accurate coding is essential for reliable data collection and effective cancer treatment planning.
