About coding Orchioblastoma
The ICD-10-CM code for Orchioblastoma is C62.9 (Malignant neoplasm of testis, unspecified whether descended or undescended).
Within C62, choose C62.9 (unspecified whether descended or undescended) only when documentation doesn't support a more specific option: undescended testis (C62.0) and descended testis (C62.1).
To report this condition, pick the subcode that matches the documentation: C62.90 (undescended), C62.91 (undescended) and C62.92 (undescended).
Use an additional code to identify any functional activity.
