ICD-10-CM 2027
ICD-10 code for screening
From the official ICD-10-CM alphabetic index entry “Screening (for)”. Page updated September 29, 2026.
About coding screening
The ICD-10-CM code for screening is Z13.9 (Encounter for screening, unspecified). The official index lists 219 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z13.9.
Within Z13, choose Z13.9 (screening, unspecified) only when documentation doesn't support a more specific option: screening for diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (Z13.0), screening for diabetes mellitus (Z13.1), screening for nutritional, metabolic and other endocrine disorders (Z13.2), screening examination for mental health and behavioral disorders (Z13.3), screening for certain developmental disorders in childhood (Z13.4), screening for eye and ear disorders (Z13.5), screening for cardiovascular disorders (Z13.6), screening for genetic and chromosomal anomalies (Z13.7) and 1 more.
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.
