Collaborative Stage

Note 1: Code only for cases described as arising from a benign pleomorphic adenoma. The diagnosis may be stated as carcinoma ex pleomorphic adenoma or carcinoma arising from a mixed tumor or mixed tumor of salivary gland type. The histology code assigned to the case may be 8941/3, or other codes for carcinoma. Use code 987 for all other cases not described as arising from a benign adenoma.
Note 2: Use code 001 for no invasion beyond capsule. Use code 002 for invasion beyond capsule measured as less than 1.5mm. For all cancers with invasion 1.5mm or greater beyond the capsule, code measured invasion beyond the capsule into adjacent tissue as stated on the pathology report.

Code	Description
001	Noninvasive, confined within the capsule
002	Minimally invasive, less than 1.5 mm invasion beyond capsule of pleomorphic adenoma into adjacent tissue
015-979	1.5 - 97.9 millimeters of invasion beyond capsule of pleomorphic adenoma into adjacent tissue Code exact measurement in HUNDREDTHS of millimeters. Examples: 015 1.5 millimeters 020 2.0 millimeters 100 10 millimeters 150 15 millimeters, 1.5 centimeters
980	98.0 millimeters or greater invasion
987	Not applicable, not carcinoma ex pleomorphic adenoma
988	Not applicable: Information not collected for this case (May include cases converted from code 888 used in CSv1 for "Not applicable" or when the item was not collected. If this item is required to derive T, N, M, or any stage, use of code 988 may result in an error.)
997	Pathologic examination of primary tumor, results not available
998	No pathologic examination of primary tumor
999	Unknown, size not stated Not documented in patient record
