Tiered Specialty Contracting Strategy for Network Builds: Getting Hard-to-Contract Providers Signed

Why Specialty Tiering Matters in Network Builds

Every network build operates under a filing deadline that is functionally immovable. The HPMS submission window for Medicare Advantage benefit year filings opens and closes on CMS's schedule, and the adequacy model that feeds the submission must reflect a network that has been contracted and credentialed — not a network that is in progress. This deadline reality means that the sequence in which a plan contracts providers matters enormously. Start with the wrong specialties, exhaust your recruiter bandwidth on easy wins, and discover at week 14 that you have no oncologists signed — and you're filing exceptions that could have been avoided with better prioritization.

A tiered specialty contracting strategy addresses this sequencing problem by explicitly classifying specialties into priority tiers based on their strategic importance, their contracting difficulty, and their impact on adequacy. The tiering framework tells your recruitment team where to spend effort first, how much compensation authority to deploy at each stage, and when to pivot from direct negotiation to alternative strategies for providers who won't sign.

Tiered contracting is also a budget discipline. Physician and specialist compensation rates vary dramatically across specialty categories, and the willingness of specific provider groups to contract at market rates — versus demanding above-market rates or value-add concessions — varies with their market power. A tiering framework that allocates compensation authority by tier allows network leadership to make deliberate decisions about where premium rates are strategically justified and where standard market rates should be held.

The Three-Tier Framework

The most effective tiered contracting frameworks for Medicare Advantage network builds use a three-tier structure that groups specialties by their strategic function in the network.

Tier 1: Anchor specialists are the high-acuity, hard-to-contract specialty groups whose participation is non-negotiable for adequacy and whose absence creates the most member-access risk. These are typically the specialists that CMS scrutinizes most intensely in adequacy reviews and that members most urgently need when they face serious health events. Anchor specialists require the most senior recruiter assignment, the longest outreach runway, and the highest compensation authority. Outreach to Tier 1 specialists should begin at the very start of the network build — week one or two — because their contracting timelines are the longest and their negotiation complexity is the highest.

Tier 2: Secondary fill providers are specialties that are important for adequacy and member access but where the contracting process is more standardized and the provider market is less concentrated. These specialties often have larger pools of available providers, more competitive compensation environments, and faster contracting timelines. Tier 2 outreach should begin in parallel with Tier 1 but with less senior recruiter assignment and standard compensation authority.

Tier 3: Access exception backstops are specialty categories where the provider market is thin in one or more of your service area counties, making full adequacy through contracting unlikely. These specialties are candidates for exception filing from the outset, but the exception filings require documented outreach — which means Tier 3 providers still need to be contacted, even though successful contracting is not the primary expectation. Tier 3 outreach focuses on generating the documentation for exception filings rather than on achieving contract execution, and the recruiter effort is calibrated accordingly.

Which Specialties Go in Which Tier and Why

The specific specialty assignment to tiers varies by market — a specialty that is abundant in a metropolitan market may be a Tier 1 challenge in a rural service area. But certain specialties consistently appear in Tier 1 across most market types because of their universal contracting difficulty and their high adequacy stakes.

Tier 1 specialties typically include oncology (medical and radiation), behavioral health (psychiatry specifically, which is chronically under-supplied in most markets), interventional cardiology, neurosurgery, and maternal-fetal medicine. These specialties share common characteristics: high national demand relative to supply, provider groups with significant market leverage, and frequent employment arrangements with health systems that create system-level contracting complexity rather than individual provider negotiations.

Tier 2 specialties typically include general cardiology, orthopedic surgery, gastroenterology, dermatology, pulmonology, and endocrinology. These specialties have larger provider pools in most markets, more active independent physician groups open to direct contracting, and more standardized compensation benchmarks. They are still important for adequacy — CMS evaluates all of them — but the contracting process is more amenable to standard recruiter workflows.

Tier 3 specialties — those most likely to require exception filings in thin markets — typically include rheumatology, infectious disease, allergy and immunology, nephrology, and certain surgical subspecialties. These specialties have limited supply nationally, are often employed by academic medical centers or large hospital systems with complex system-level contracting requirements, and are genuinely absent from many rural and semi-rural county markets. In markets where these specialties are thin, your contracting team should be building the exception file from day one rather than expecting to contract a provider who may not exist within reasonable proximity.

Compensation Authority Tiers by Specialty Category

Compensation authority — the rate range within which a recruiter can offer rates without senior leadership approval — should be stratified by specialty tier to match the market realities of each specialty category. A compensation authority framework prevents both underbidding (losing Tier 1 anchors because the recruiter couldn't offer a competitive rate) and overbidding (paying above-market rates for Tier 2 fill providers where competitive rates are sufficient).

Tier 1 authority levels should reflect the upper range of relevant market benchmarks — typically CMS Medicare fee schedule percentages calibrated to what competing MA plans are paying in the same market, plus a modest premium to incentivize participation. For oncology and psychiatry in many markets, this means rates at 110–120% of Medicare fee schedule for professional services, with potential for additional value-add considerations like care management fee arrangements or practice support provisions.

Tier 2 authority levels should reflect market-competitive rates without premium — typically 95–105% of Medicare fee schedule for professional services, calibrated to what your competitive analysis indicates the market bears. Tier 2 negotiations that require escalation above this range should trigger a review of whether the provider is actually a Tier 2 fit or whether their market leverage warrants Tier 1 treatment.

Tier 3 authority should be set conservatively because the primary goal in Tier 3 is exception-file documentation rather than contract execution. If a Tier 3 provider accepts standard rates, excellent — execute the contract and count the adequacy credit. But the contracting team should not spend negotiating energy on above-market concessions for Tier 3 specialties when those resources are better deployed on Tier 1 anchors whose participation actually determines adequacy.

Sequencing Outreach for Maximum Conversion Rate

Sequencing outreach intelligently is as important as the tier classification itself. The goal is to structure your outreach calendar so that the longest-lead items begin earliest, the highest-leverage conversations happen when your contracting team has the most information and preparation, and the documentation trail for exception filings is building in parallel with active negotiation.

Weeks 1–4 of the network build should focus exclusively on Tier 1 identification and initial outreach. This phase begins with market intelligence gathering: identifying which providers in each Tier 1 specialty are currently contracted with competing MA plans, which are independent versus health system employed, and which have a track record of participating in MA contracting. This intelligence shapes your outreach sequencing — independent providers are typically faster to contract than employed physicians whose agreements require system-level approval, so starting with the former gives you early credentialing starts while the longer health system conversations proceed in parallel.

Weeks 4–8 should see Tier 2 outreach beginning at scale, Tier 1 negotiations advancing to rate discussion, and Tier 3 initial outreach generating the first wave of outreach documentation. At this point, your exception-file building for Tier 3 is already four weeks in, which is valuable — CMS reviewers want to see outreach logs that demonstrate sustained effort, and logs that begin 30 days before the filing window are weaker than logs that begin 90 days out.

Weeks 8–12 are the highest-intensity negotiation phase. Most Tier 1 negotiations that are going to close will be in active rate discussion by this point. Tier 2 contracting should be moving to execution. Tier 3 outreach should be complete enough to support exception filing documentation. Network leadership should be monitoring weekly against a specialty-by-county adequacy dashboard to identify any emerging gaps that require mid-course tactical adjustments.

Negotiation Leverage Points for Tier 1 Anchor Specialists

Tier 1 specialists — particularly in high-demand specialties like oncology, psychiatry, and interventional cardiology — often have significant market power relative to any individual plan. Their practices or health system employers may already be contracted with multiple competing MA plans and can afford to be selective. Effective negotiation with Tier 1 anchors requires understanding what they value beyond the contracted rate and structuring the conversation around those value points.

Administrative simplicity is consistently cited by specialist practices as a primary contracting decision factor. Plans that offer streamlined prior authorization processes for the procedure codes most relevant to a given specialty — reduced PA requirements for oncology chemotherapy protocols, for example, or expedited appeals processes for cardiac catheterization — are more attractive contracting partners than plans that offer slightly higher rates but burdensome prior-auth requirements.

Prompt payment terms matter more than many plans appreciate. Specialist practices with high procedural volumes have significant working capital needs, and plans that offer consistently faster-than-standard payment timelines — or that structure clean claims payment at 14 days rather than the standard 30 — can use that as a genuine differentiating concession in negotiations where the rate discussion has stalled.

For health system-employed specialists, the conversation often needs to be had at the system level rather than the individual provider level. Building a relationship with the health system's managed care contracting team and framing the plan's participation as part of a broader system-level partnership — potentially including facility contracting, quality incentive arrangements, or joint care management programs — changes the dynamic from a transactional rate negotiation to a strategic partnership discussion. These conversations take longer but often result in system-level agreements that bring multiple Tier 1 specialists on board simultaneously.

When Tier 1 Outreach Fails at Week 10

Despite best efforts, Tier 1 outreach does not always succeed. A health system may be under an exclusivity arrangement with a competing plan. A specialist group may have a policy against participating in MA plans below a minimum enrollment threshold you don't meet in a new market. Individual providers may simply decline to participate regardless of rate. When the week 10 review reveals that Tier 1 outreach in a given county-specialty combination has failed to produce a signed agreement, the tactical response depends on whether the gap is closeable through alternative means or requires exception filing.

Alternative contracting channels for Tier 1 failures include: reaching out to providers in adjacent counties who may fall within the time-distance threshold from the gap county's population centroid; exploring participation in a shared-risk arrangement with a competing plan that has the specialist contracted (known as network sharing or network rental arrangements in markets where these exist); and engaging staffing or locum tenens agencies to place a contracted provider in the gap county on a time-limited basis that bridges the submission cycle.

If all alternative channels have been exhausted by week 10 and the gap persists, the exception-filing preparation must become the primary focus for that county-specialty combination. The exception file at this point should already have 8-10 weeks of documented outreach. The remaining 2-4 weeks before submission should focus on completing the outreach documentation, drafting the exception rationale narrative, and preparing the access-continuity commitment that will accompany the exception. A thorough, well-documented exception filed for a genuinely difficult market is a defensible outcome; a thin exception filed for a gap that received inadequate outreach attention is a compliance vulnerability. Build the file while you still have time to make it strong.
