Carbohydrate Antigen 19-9 (CA 19-9) Lab Value
Notes
**Note 1:** Carbohydrate Antigen 19-9 (CA 19-9) is a tumor marker that has value in the management of certain malignancies. **Note 2:** Record, to the nearest tenth of in Unit/milliliter (U/ml), the highest CA 19-9 lab value recorded in the medical record prior to treatment. * For example: A pretreatment CA 19-9 of 60.0 U/mL would be recorded as 600 **Note 3:** Code 000 is reserved for exactly 0.0 U/mL (no measurable amount of CA 19 9). Do not round tiny values down to 0.0 U/mL; any measured value less than or equal to 0.1 U/mL should be coded 001. * For code 001, also round 0.11 - 0.14 U/mL down to 0.1 U/mL * For codes 002-980, round values to the nearest tenth of a U/ml **Note 4:** Use code 997 if an interpretation is documented but the actual lab value is not available in the record.Default
