About coding Odontosarcoma
The ICD-10-CM code for Odontosarcoma is C41.1 (Malignant neoplasm of mandible). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on C41.1.
Within C41 (malignant neoplasm of bone and articular cartilage of other and unspecified sites), C41.1 is specifically for malignant neoplasm of mandible. Related codes cover bones of skull and face (C41.0), vertebral column (C41.2), ribs, sternum and clavicle (C41.3), pelvic bones, sacrum and coccyx (C41.4) and bone and articular cartilage, unspecified (C41.9).
The conditions in its Excludes2 note aren't part of C41.1, but may be coded alongside it if the patient has both: jaw NOS (C03.9), lower (C03.1) and malignant neoplasm of upper jaw bone (C41.0).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
