How Z Codes Help Eliminate Patients Barriers to Care

Act

Effective date
Not stated in the notice

Oct 3, 2026

Summary

Horizon Blue is encouraging providers to use Z codes (ICD-10 social determinant of health codes) to document nonmedical barriers to care such as housing instability, food insecurity, and unemployment. While Z codes are not currently reimbursable, documenting them enables care coordination triggers, supports quality metrics (HEDIS), and helps identify high-risk members for intervention programs. Providers should begin incorporating Z codes into clinical documentation to enable comprehensive member support and care management referrals.

What to do

immediately · 6 steps
01Providers and clinical staff should begin documenting social determinants of health using Z codes during patient encounters.
02Billing and coding team should not bill Z codes for reimbursement (they are not reimbursable), but should ensure codes are captured in the medical record to trigger care coordination and case management workflows.
03Update encounter forms and EMR templates to include prompts for screening and documenting SDoH factors.
04Providers should reference the CMS infographics and CDC ICD-10-CM browser tool (provided in policy) to identify appropriate Z codes.
05Route identified members with SDoH risks to care management, member life coaching, behavioral health referrals, or the Health Equity Member Resource Team (HealthEquityResources@HorizonBlue.com) for support.
06No billing system changes are required since Z codes are not billable, but documentation capture and care coordination workflows must be implemented.
