Health Professional Shortage Areas and Network Adequacy: What HPSA Designation Means for Your Filing

What HPSA Designation Means

A Health Professional Shortage Area (HPSA) is a geographic area, population group, or facility that the Health Resources and Services Administration (HRSA) has designated as having an insufficient supply of healthcare providers to meet the health needs of the residents or population served. HPSA designations are made under Section 332 of the Public Health Service Act and are maintained by HRSA's Bureau of Health Workforce. The designation is used across federal programs — from National Health Service Corps loan repayment to Medicare rural health incentives to network adequacy exception filings — as an objective indicator that provider supply in a given area is structurally insufficient relative to population need.

HPSA designations are made in three primary care categories: primary care (physicians, physician assistants, and nurse practitioners delivering primary care services), dental care (dentists and dental hygienists), and mental health (psychiatrists, psychologists, clinical social workers, and licensed professional counselors). Each category is assessed independently, meaning that a county or service area may have a primary care HPSA designation without a mental health designation, or may carry designations in all three categories simultaneously. For Medicare Advantage network adequacy, the mental health and primary care HPSA categories are most directly relevant, as these align with the specialty categories CMS evaluates most closely in the adequacy review process.

HPSA designations are periodically reviewed and updated by HRSA as provider supply and population demographics change. A designation can be removed if a sufficient number of new providers enter the area and the shortage metric falls below the threshold for designation. Plans should verify the current designation status of each county in their service area annually — particularly in markets experiencing provider supply growth from rural health initiatives, medical school expansions, or NHSC placement activity — because a county that was designated at the time of a prior adequacy exception filing may no longer carry that designation at the time of the current filing.

HPSA Scores and Their Significance

Each HPSA designation carries a numeric score that reflects the severity of the shortage. Primary care HPSA scores range from 0 to 25; mental health and dental HPSA scores also have defined ranges. Higher scores indicate more severe shortages — a higher ratio of population to providers, a larger geographic isolation factor, or a higher proportion of the population below 100% of the federal poverty level, which is one of the demand-side factors that contributes to the HPSA score calculation.

HPSA scores matter for MA network adequacy in two related ways. First, they serve as objective documentation of the severity of the provider shortage in the designated area, which is relevant to the strength of an exception filing that cites HPSA status as justification for an adequacy gap. CMS reviewers are more receptive to exception filings in counties with high HPSA scores — indicating severe, well-documented shortages — than in counties with low HPSA scores, which may indicate marginal shortages where active recruitment could reasonably have been expected to produce results. The HPSA score is, in effect, an objective proxy for how hard it would be for a plan to recruit providers in a gap county, and higher scores carry proportionally more weight in the exception justification narrative.

Second, HPSA scores affect the prioritization of federal programs that can affect provider supply in shortage areas. The National Health Service Corps (NHSC), which places providers in HPSA areas in exchange for loan repayment assistance, prioritizes placements in areas with higher HPSA scores. Plans that are recruiting in high-score HPSA counties may find that NHSC-placed providers are available as contracting candidates — these providers are by definition located in shortage areas and are contractually committed to serving all patients regardless of payer, making them receptive contracting targets in markets where independent practice recruitment is difficult.

How HPSA Status Affects Provider Availability in Adequacy Calculations

HPSA designation directly affects provider availability in the areas where it applies. The structural provider shortage documented by the HPSA designation means that the absolute number of providers available for recruitment is smaller than in non-designated areas, the providers who are present typically have full panels across multiple payers already, and new provider supply through training pipelines or market entry is constrained by the same factors that produced the shortage in the first place. For network adequacy purposes, this means that HPSA counties are genuinely harder to build adequate networks in — not because plans aren't trying, but because the providers aren't there.

CMS's adequacy calculation does not automatically adjust time-distance thresholds or minimum adequacy ratios for HPSA counties. The same adequacy standards that apply in non-HPSA counties apply in HPSA counties, with the same consequences for plans that fail to meet them. The HPSA accommodation within the adequacy system operates through the exception filing process rather than through automatic threshold relaxation: plans that demonstrate genuine, documented recruitment efforts in HPSA counties and still cannot achieve adequate networks are eligible to file exceptions citing the structural provider shortage as the basis for the gap.

This distinction matters for how plans approach network building in HPSA counties. The HPSA designation does not relieve plans of the obligation to attempt to build adequate networks in those counties — it provides a credible basis for documenting why those efforts fell short and seeking exception relief when they do. Plans that cite HPSA status in exception filings without accompanying evidence of genuine recruitment activity are likely to receive unfavorable review. The exception filing tells the story of what the plan tried to do in the face of structural shortage, and the HPSA designation corroborates that the shortage was real. Both elements are necessary.

CMS Guidance on HPSA Counties and Exception Filings

CMS's guidance on network adequacy exception filings recognizes HPSA designation as a relevant factor in evaluating the reasonableness of a plan's adequacy gaps. The Medicare Managed Care Manual and the annual network adequacy guidance documents reference HRSA-designated shortage areas as a category of geographic circumstance that may support exception relief. However, CMS does not provide a blanket exception for all HPSA counties — the agency evaluates each exception filing on its merits, assessing the quality of the plan's outreach documentation, the alternatives the plan has identified for members, and the plan's trajectory toward closing the gap over time.

The best-practice exception filing for a HPSA county includes several elements that CMS reviewers look for: a clear statement of the HPSA designation category and score, with documentation sourced directly from HRSA's data systems (HRSA publishes HPSA scores in its data downloads and Shortage Area Find tool); a detailed outreach log showing the specific providers that were contacted, the dates of contact, the method of contact, and the outcome of each contact attempt; a narrative explanation of why contacted providers were unavailable — whether due to panel closure, non-participation in Medicare Advantage, retirement, or other documented reasons; a description of the access alternatives the plan has arranged for members in the gap county, such as out-of-network cost-sharing waivers or telehealth arrangements where applicable; and a recruitment action plan that shows what the plan intends to do to continue closing the gap in future benefit years.

CMS has signaled in its Final Rule commentaries that it is more likely to grant exception relief in genuinely high-shortage areas when plans demonstrate that they have taken the structural supply constraints seriously and built their exception documentation accordingly. Exception filings that are thin on outreach documentation or that lack a credible forward-looking recruitment commitment receive more scrutiny even in high-HPSA counties than well-documented filings receive in moderate-HPSA counties.

Medically Underserved Areas vs. HPSA: Understanding Both Designations

The HPSA designation is often confused with the Medically Underserved Area (MUA) designation, which is a related but distinct designation maintained by HRSA under a different methodology. MUAs are geographic areas designated as having a shortage of primary care services as measured by an Index of Medical Underservice (IMU) that incorporates provider-to-population ratios, infant mortality rates, poverty rates, and the proportion of the population over 65. Where HPSA designations are specialty-specific (primary care, dental, mental health), MUA designations are population-focused and do not differentiate by specialty.

For MA network adequacy purposes, HPSA designations are more directly relevant than MUA designations because the HPSA framework aligns with the specialty-specific adequacy structure that CMS uses to evaluate MA networks. A primary care HPSA designation speaks directly to the shortage of primary care providers relevant to primary care adequacy; a mental health HPSA designation speaks directly to behavioral health adequacy. MUA designation, while useful as a general indicator of healthcare access challenges, does not carry the same specificity that CMS reviewers need to evaluate specialty-specific exception filings.

However, counties that carry both MUA and HPSA designations represent the most severe access-challenged areas in the service area, and exception filings in counties with both designations can appropriately reference both classifications as evidence of the depth of the access challenge. The combination of MUA status — indicating structural demand-side challenges including poverty and demographic factors — and HPSA status — indicating supply-side provider shortage — presents a particularly robust evidentiary basis for exception relief, because it demonstrates that the gap exists on both the supply and demand sides of the provider-patient relationship.

FQHC Presence in HPSA Counties as a Network Strategy

Federally Qualified Health Centers (FQHCs) are community-based healthcare providers that receive federal funding under Section 330 of the Public Health Service Act in exchange for serving all patients regardless of their ability to pay. FQHCs are required to be located in Health Professional Shortage Areas or Medically Underserved Areas, or to serve Medically Underserved Populations. This siting requirement means that FQHC locations are a reliable signal of where structural provider shortages exist — and more importantly for MA network planning, it means that FQHCs are often the most stable and accessible provider organizations in HPSA-designated counties.

FQHCs are eligible to participate in Medicare Advantage networks and are increasingly viewed as high-value contracting targets in HPSA counties precisely because they combine stable organizational infrastructure (FQHC status requires federal grant compliance and organizational governance that small independent practices don't have) with siting in the areas where provider shortages are most acute. An MA plan that contracts with the FQHC serving a HPSA county gains access to the provider organization specifically built to serve that shortage area, with the capacity and mission to serve patients regardless of payer. The contracting relationship is typically straightforward because FQHCs have existing administrative infrastructure for payer contracting and generally seek participation in MA networks to extend their revenue base and serve their patient communities.

For exception filing purposes, a plan that has contracted with the FQHC in a HPSA county has a meaningfully different adequacy posture than a plan that has no provider in the county at all. Even if the FQHC contract alone does not bring the county to the minimum adequacy ratio, it demonstrates genuine engagement with the provider community available in the shortage area and provides documented member access to the extent that the FQHC's capacity allows. CMS reviewers look favorably on exception filings that demonstrate FQHC contracting in HPSA counties as evidence that the plan is working with the resources the shortage area actually has available.

How Blueprint Flags HPSA Counties in the County Dashboard

Blueprint Network Hub incorporates HRSA HPSA designation data into the county adequacy dashboard, surfacing HPSA status and score as county-level attributes that are visible alongside the adequacy ratio and provider pipeline metrics for each county. Counties with active HPSA designations in primary care, mental health, or dental categories are flagged in the dashboard with the applicable designation category and current HPSA score, drawn from HRSA's publicly available data sources and updated on a quarterly basis as HRSA publishes updated designation information.

The HPSA flagging in Blueprint serves two operational purposes. First, it provides network operations teams with immediate context for why a gap county is proving difficult to fill — the HPSA flag tells the recruiter working that county that the shortage is documented at the federal level and that the standard recruitment playbook may need to be adapted for the structural constraints in that area. This context helps teams prioritize alternative strategies — FQHC contracting, telehealth access arrangements, NHSC-placed provider outreach — rather than continuing to apply standard outreach tactics in markets where those tactics are unlikely to produce different results.

Second, the HPSA data in Blueprint is integrated into the exception filing workflow. When a county is below adequacy threshold and carries a HPSA designation, Blueprint's exception filing module pre-populates the HPSA designation category and score in the exception filing template, links to the HRSA data source for documentation purposes, and prompts the user to complete the outreach log and access alternative fields that CMS requires for HPSA-county exceptions. The result is a more complete and more defensible exception filing produced with less manual data gathering — which matters in the compressed timeline of the weeks immediately before the adequacy filing deadline, when the quality of documentation work directly affects the exception review outcomes that determine whether gap counties generate deficiency findings or receive appropriate relief.
