Network Participation by location

§ Subcategory FAQ

The questions buyers ask before shortlisting.

Answered against the same disclosed methodology that powers every ranking on this page.

§FAQ.01

What is ABA Network Participation?

Network Participation is a service-vendor subcategory inside the insurance consulting group on ABA Rank. ABA Rank indexes 22 firms that operate in network participation and ranks each on the same disclosed 100-point Index used across the rest of the services directory - qualified public reviews, profile completeness, verification recency, and primary-category fit, with no paid tier among the inputs.

§FAQ.02

How does ABA Rank rank network participation firms?

Every firm in the Network Participation subcategory is scored on the same 100-point Index used across the rest of ABA Rank: 50 points from qualified public reviews, 30 points from profile completeness (the disclosed inputs specific to network participation), 15 points from verification recency, and 5 points from primary-category fit. As of methodology v3.0 no paid product contributes any Index points, and sponsored placements render in labeled slots above the ranked list rather than mixing into it. Methodology is fully disclosed at /how-we-rank.

§FAQ.03

Which network participation firm ranks #1 on ABA Rank today?

The current #1 in Network Participation is the top entry on this page; rankings refresh every night so the leader can change between visits. ABA Rank does not endorse a single permanent winner - the public Index recomputes from its four disclosed inputs (qualified public reviews, profile completeness, verification recency, and primary-category fit) on a nightly cadence, and any firm that improves its disclosed inputs can move up.

§FAQ.04

How many network participation firms are listed on ABA Rank?

22 firms are currently ranked under Network Participation on ABA Rank. 1 of 22 is Verified - meaning the vendor team has claimed the profile and completed a credential or business-registration check. The directory is an editorial index of operating U.S. ABA firms; defunct or out-of-market entries are removed.

§FAQ.05

What does Verified mean for network participation firm on ABA Rank?

Verification on a service vendor means a credential audit specific to the service line - BACB credentials for clinical service partners; business registration and references for non-clinical firms - plus a magic-link claim from a work email at the vendor’s domain. Verified service vendors carry a seal and a fresh verification date feeding an operational Index signal; unverified vendors remain ranked but are clearly marked. Verification is not a paid ranking boost.

§FAQ.06

How much do network participation firms cost?

Network Participation pricing varies widely by service line. ABA Rank publishes each vendor’s disclosed pricing model and pricing band on its profile when provided - there is no paid placement and no hidden referral commission. For deeper procurement work, /post-a-project routes a brief to three to seven matched vendors with disclosed pricing comparable side by side.

§FAQ.07

How does ABA Rank decide which firms qualify for Network Participation?

Subcategory assignment is editorial, not self-selected. The ABA Rank editorial team reviews each firm’s public website, primary service lines, and (where applicable) credential records, then assigns the most specific subcategory that matches what the firm actually does. Firms that span multiple subcategories appear in each one rather than being forced into a single bucket.

§FAQ.08

How can a firm get listed in Network Participation?

Any owner or authorized representative of an eligible firm can claim a free listing. Claimed profiles unlock the editable fields that drive the Index, and Verified ($490/yr) and Sponsor ($1,490/yr) tiers are optional paid upgrades disclosed in the methodology. New firms that are not yet on ABA Rank can be submitted at /suggest-vendor; submissions are reviewed weekly and approved listings typically appear within seven to ten days.
