About coding Circumscribed cerebellar sarcoma
The ICD-10-CM code for Circumscribed cerebellar sarcoma is C71.6 (Malignant neoplasm of cerebellum).
Within C71 (malignant neoplasm of brain), C71.6 is specifically for malignant neoplasm of cerebellum. Related codes cover cerebrum, except lobes and ventricles (C71.0), frontal lobe (C71.1), temporal lobe (C71.2), parietal lobe (C71.3), occipital lobe (C71.4), cerebral ventricle (C71.5), stem (C71.7), overlapping sites of brain (C71.8) and 1 more.
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.
In MS-DRG v44.0, it is part of the grouping logic for DRG 054 (Nervous System Neoplasms with MCC, relative weight 1.5194) and DRG 055 (Nervous System Neoplasms without MCC, relative weight 1.0296), in MDC 01 (Diseases and Disorders of the Nervous System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
