Collaborative Stage

Note 1: Record the range of the alpha fetoprotein (AFP) test as documented in the patient record after orchiectomy and prior to further treatment.
Note 2: Use the same laboratory test to record values for CS Site-Specific Factors 12 and 13.
Note 3: A lab value expressed in micrograms/liter (ug/L) is equivalent to the same value expressed in nanograms/milliliter (ng/ml).
Note 4: If the initial post-orchiectomy AFP test remains elevated, review the subsequent tests until normalization or plateau occurs and use that test to code this field. See Part I for further explanation of serum tumor marker half life.
Note 5: If the post-orchiectomy AFP test is unknown but the preorchiectomy AFP test was normal, use code 990.
Note 6: If the post-orchiectomy AFP test is unavailable but a physician's statement of the result is documented, use codes 991-993.
Note 7: For rare cases that are treated prior to orchiectomy or an orchiectomy is not performed, code the initial AFP range in this field and not in CS Site-Specific Factor 7.

Code	Description
000	Within normal limits (S0)
010	Range 1 (S1) above normal and less than 1,000 nanograms/milliliter (ng/ml)
020	Range 2 (S2) 1,000 -10,000 ng/ml
030	Range 3 (S3) greater than 10,000 ng/ml
988	Not applicable: Information not collected for this case (If this information is required by your standard setter, use of code 988 may result in an edit error.)
990	Post-orchiectomy alpha fetoprotein (AFP) unknown but preorchiectomy AFP was normal
991	Post-orchiectomy AFP stated to be still elevated
992	Post-orchiectomy AFP unknown but post-orchiectomy serum tumor markers NOS stated to be normal
993	Post-orchiectomy AFP unknown but post-orchiectomy serum tumor markers NOS stated to be still elevated Stated as Stage IS
997	Test ordered, results not in chart
998	Test not done (test not ordered and not performed)
999	Unknown or no information Not documented in patient record
