About coding Germinoblastoma
The ICD-10-CM code for Germinoblastoma is C85.9 (Non-Hodgkin lymphoma, unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on C85.9.
Within C85, choose C85.9 (Non-Hodgkin lymphoma, unspecified) only when documentation doesn't support a more specific option: unspecified B-cell lymphoma (C85.1), mediastinal (thymic) large B-cell lymphoma (C85.2) and other specified types of non-Hodgkin lymphoma (C85.8).
To report this condition, pick the subcode that matches the documentation: C85.90 (unspecified site), C85.91 (lymph nodes of head, face, and neck), C85.92 (intrathoracic lymph nodes), C85.93 (intra-abdominal lymph nodes), C85.94 (lymph nodes of axilla and upper limb), C85.95 (lymph nodes of inguinal region and lower limb), C85.96 (intrapelvic lymph nodes), C85.97 (spleen) and 3 more.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
