C46.2Kaposi's sarcoma of palate

C46.2 is the ICD-10-CM diagnosis code for Kaposi's sarcoma of palate. It belongs to category C46 (Kaposi's sarcoma), block C45-C49 (malignant neoplasms of mesothelial and soft tissue) and chapter 2 (neoplasms). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within C46 (Kaposi's sarcoma), C46.2 is specifically for Kaposi's sarcoma of palate. Related codes cover of skin (C46.0), of soft tissue (C46.1), of lymph nodes (C46.3), of gastrointestinal sites (C46.4), of lung (C46.5), of other sites (C46.7) and unspecified (C46.9).

Code first: any human immunodeficiency virus [HIV] disease (B20).

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 011 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCC, relative weight 5.6154), DRG 012 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CC, relative weight 4.381), DRG 013 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCC, relative weight 2.7307), DRG 146 (Ear, Nose, Mouth and Throat Malignancy with MCC, relative weight 2.1329), DRG 147 (Ear, Nose, Mouth and Throat Malignancy with CC, relative weight 1.3055), DRG 148 (Ear, Nose, Mouth and Throat Malignancy without CC/MCC, relative weight 0.8008) and 3 more, in Pre-MDC, MDC 03 (Diseases and Disorders of the Ear, Nose, Mouth and Throat) and MDC 25 (Human Immunodeficiency Virus Infections), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 176.2 (Kaposi's sarcoma, palate).
