Urology Coding Alert

Get specific with laterality.

When you still coded diagnoses based on ICD-9, your options for testicular biopsies were simple: 186.9 (Malignant neoplasm of other and unspecified testis) if malignant, and 222.0 (Benign neoplasm of testis) if benign. That changed once ICD-10 went into effect, giving you much more specific diagnoses for reporting.

Malignant Neoplasm of Testis

• C62.10 – Malignant neoplasm of unspecified descended testis
• C62.11 – Malignant neoplasm of descended right testis
• C62.12 – Malignant neoplasm of descended left testis
• C62.90 – Malignant neoplasm of unspecified testis, unspecified whether descended or undescended
• C62.91 – Malignant neoplasm of right testis, unspecified whether descended or undescended
• C62.92 – Malignant neoplasm of left testis, unspecified whether descended or undescended

Benign Neoplasm of Testis

• D29.20 – Benign neoplasm of unspecified testis
• D29.21 – Benign neoplasm of right testis
• D29.22 – Benign neoplasm of left testis.
