About coding neoplasm screening
The ICD-10-CM code for neoplasm screening is Z12.9 (Encounter for screening for malignant neoplasm, site unspecified). The official index lists 29 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z12.9.
Within Z12, choose Z12.9 (neoplasm, site unspecified) only when documentation doesn't support a more specific option: neoplasm of stomach (Z12.0), neoplasm of intestinal tract (Z12.1), neoplasm of respiratory organs (Z12.2), neoplasm of breast (Z12.3), neoplasm of cervix (Z12.4), neoplasm of prostate (Z12.5), neoplasm of bladder (Z12.6), neoplasm of other genitourinary organs (Z12.7) and 1 more.
Use an additional code to identify any family history of malignant neoplasm (Z80.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
