About coding testis teratoma
The ICD-10-CM code for testis teratoma is C62.9 (Malignant neoplasm of testis, unspecified whether descended or undescended). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on C62.9.
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.
