Collaborative Stage

Note 1: Chromoganins are a family of proteins in secretory granules found throughout the neuroendocrine system. Serum Chromagranin A (CgA) has shown to be a useful marker for neuroendocrine tumors.
Note 2: Record the nearest nanogram/milliliter (ng/ml) the highest CgA lab value recorded in the medical record prior to treatment. For example, code a pretreatment CgA of 400 ng/ml as 400.
Note 3: Code 000 is reserved for exactly 0.0 ng/ml (no measurable amount of CgA). Do not round tiny values down to 0 ng/ml; any measured value less than or equal to 1 ng/ml should be coded 001. For code 001, also round 1.1-1.4 ng/ml down to 1 ng/ml. For codes 002-979, round values to the nearest ng/ml.
Note 4: For an uncertain value, record the stated closest value. For example, code a value stated as "less than 5 ng/ml" as 005.

Code	Description
000	CONVERTED AND CODE REUSED V0203 Prior to V0203 code defined as "Test not done (test not ordered or not performed)". Cases converted to code 998 with V0203 and code 000 redefined as "0 nanogram/milliliter (ng/ml)". 0 nanogram/milliliter (ng/ml)
001	1 or less ng/ml
002-979	002-979 ng/ml
980	980 or greater 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.)
997	Test ordered, results not in chart
998	CONVERTED AND CODE REUSED V0203 Prior to V0203 code defined as "Test ordered, results not in chart". Cases converted to code 997 with V0203 and code 998 redefined as "Test not done (test not ordered and not performed)". Test not done (test not ordered and not performed)
999	Unknown or no information Not documented in patient record
