About coding Annual examination
The ICD-10-CM code for Annual examination is Z00.00 (Encounter for general adult medical examination without abnormal findings). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z00.00.
Within Z00.0, choose Z00.00 (without abnormal findings) only when documentation doesn't support a more specific option: with abnormal findings (Z00.01).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
