Summary

Healthcare providers must now use the most specific Social Determinants of Health (SDOH) Z codes (Z55-Z65) when documenting patient circumstances on claims and encounters. For categories Z55, Z58, Z59, and Z62, providers must drill down to the most descriptive subcodes rather than using general category codes.

Action Required

Action needed
Immediately: Providers and coding staff must update documentation practices to use the most specific SDOH Z codes available. For Z55, Z58, Z59, and Z62 categories, drill down to subcodes instead of using general category codes. Update EMR templates and coding guidelines to require specific Z codes like Z59.12 for inadequate housing utilities instead of Z59.1 for general inadequate housing. Train staff on proper SDOH code selection to improve care coordination and health disparity identification.
