Site-Specific Factor 3

Carcinoembryonic Antigen (CEA) Lab Value


**Note 1:** CEA is a tumor marker that has value in the management of certain malignancies. **Note 2:** The same laboratory test should be used to record information in **Site-Specific Factor 1, Carcinoembryonic Antigen (CEA)** and **Site Specific Factor 3, Carcinoembryonic Antigen (CEA) Lab Value**. **Note 3:** Record to the nearest tenth in nanograms/milliliter (ng/ml) the highest CEA lab value documented in the medical record prior to treatment. * For example, code a pretreatment CEA of 7 ng/ml as 070 **Note 4:** Code 000 is reserved for exactly 0.0 ng/ml (no measurable amount of CEA). Do not round tiny values down to 0.0 ng/ml; any measured value less than or equal to 0.1 ng/ml should be coded 001. * For code 001, also round 0.11-0.14 ng/ml down to 0.1 ng/ml * For codes 002-980, round values to the nearest tenth of a ng/ml **Note 5:** For an uncertain value, record the stated closest value. * For example, code a value stated as "less than 0.5 ng/ml" as 005
