About coding upper jaw bone odontosarcoma
The ICD-10-CM code for upper jaw bone odontosarcoma is C41.0 (Malignant neoplasm of bones of skull and face).
Within C41 (malignant neoplasm of bone and articular cartilage of other and unspecified sites), C41.0 is specifically for malignant neoplasm of bones of skull and face. Related codes cover mandible (C41.1), 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 C41.0, but may be coded alongside it if the patient has both: maxillary sinus (C31.0), upper jaw (C03.0) and malignant neoplasm of jaw bone (lower) (C41.1).
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.
