What is Health Service Delivery (HSD) Table

Health Service Delivery (HSD) Table Definition

The HSD Table is the "Quantitative Proof" of a plan’s network. For Payer Ops, generating these tables is an intensive exercise in data precision. The table requires every provider to be mapped to a specific "CMS Specialty Code" and a "County Code." If the data is messy—for example, if a provider's NPI is valid but their office address is a billing office instead of a clinical site—the HSD calculation will fail the "Time and Distance" test. For Executives, the HSD results are the "Go/No-Go" for market expansion. If the tables show a deficiency in even one required specialty, the plan cannot launch in that county. Modern PLM systems include "HSD Preview" tools that allow plans to run these calculations internally throughout the year, identifying and closing "Network Gaps" long before the formal submission deadline.

FAQs

What are "Provider Supply" entries in an HSD table?

These are the entries for individual practitioners; "Facility Supply" entries are the corresponding entries for hospitals, pharmacies, and clinics.

What happens if an HSD table submission "Fails"?

CMS issues a "Deficiency Report." The plan then has a limited window to either contract with new providers to fill the gap or submit an "Exception Request" explaining why the gap cannot be filled.

How does "Provider Taxonomy" relate to HSD codes?

Payers must map their internal taxonomy codes to the specific CMS-defined specialty codes required for the HSD table; incorrect mapping is a leading cause of technical failures.
