MHK and the Hidden Cost of a Handoff

Somewhere inside a regional health plan, the people handling complaints were doing their jobs. The databases were doing theirs. The files were, presumably, filed. Yet provider disputes kept accumulating. This is the sort of failure that arrives without a dramatic crash: everybody stays busy, and the queue grows anyway.

In an anonymous case study published by MHK, the plan covered more than 171,000 members. Its appeals team worked across separate records and manual processes. “It slowed everything down having to do things manually,” its director recalled. The interesting detail is that the system had functioned for years. Competence was keeping an awkward arrangement alive.

01 / The queue nobody could see

The plan chose MHK’s CareProminence complaints, appeals and grievances suite. It brought cases into a common system, tracked their progress and gave the team a clearer account of what needed attention. The published results include a 94% reduction in total provider-dispute inventory over six months and 27% fewer provider-dispute inquiries to the call center.

These are vendor-published results from one unnamed customer, rather than a forecast for the next buyer. The case’s charts also cover 2019-2020, although the document carries a 2025 copyright. The distinction matters: this is a worked example of an operational change, not a fresh measurement of MHK’s entire customer base.

There is a plausible mechanism here. A provider waiting for an answer may call to ask where it is. The call creates more work for the organization already struggling to answer. Clear the original queue, and some of the work surrounding the queue disappears too. That is an editorial reading of the case, but it explains why a workflow improvement can reach beyond the department that buys it.

The first thing to strain was capacity. Adding more skill to a system of scattered records would still leave the records scattered. MHK’s proposition begins at that seam: give the next person the case, its context and its remaining steps together.

02 / Two kinds of paperwork, one member

MHK operates in the business-to-business software market for American health plans, pharmacy benefit managers and managed care organizations. The person whose care is being coordinated is the member. The organization buying the software is usually the payer or administrator. This distinction explains both the product and its relative invisibility to the public.

CareProminence is the clinical side. It supports care coordination, utilization review, pharmacy operations, appeals and quality measurement. MarketProminence handles the administrative life of membership, including enrollment, premium billing and financial reconciliation. The company sells SaaS through a consultative sales process; a prospective client can request a demonstration.

Consider the buyer’s problem as a sequence. Can the organization establish membership? Can its care team find the relevant history? Can a reviewer follow the required process? Can the plan reconstruct what happened afterward? Each question sounds modest. Their combined answer is a substantial enterprise software business.

Clever Care, a Southern California Medicare Advantage plan, went live with MarketProminence in 2024. The announcement describes a selection based on flexibility, with enrollment applications, health risk assessments and broker-facing tools among the intended uses. This is a useful named example of the membership side of the business.

The economics are contractual rather than retail. There is no meaningful shopping-cart price to attach to this profile. For a buyer, the relevant calculation would include configuration, integration, training and ongoing administration alongside the software contract. A saved minute has value only if the surrounding organization can put it to use.

03 / A rule is a memory that scales

A second anonymous MHK case concerns a nonprofit plan returning to Medicare Advantage after an eight-year absence. The team initially considered building its tools internally. It eventually chose MarketProminence. The account reports nearly 10,000 members added in the first year and 14,000 at the time of the case.

Its more revealing passage concerns unfamiliar transaction codes. Staff could configure a workflow for a recurring scenario, so the next instance did not require the same manual rescue. Monthly recertification also moved from manual work to automation. “They encourage autonomy,” the enrollment manager said of MHK’s approach to training administrators.

“They encourage autonomy.”

This supplies a lesson a reader can copy without buying healthcare software. Keep a record of recurring exceptions. Decide which deserve a repeatable response. Assign someone to maintain that response. Then check whether the queue actually shrinks. Automation becomes useful when the organization can remember what it learned last Tuesday.

It also places a condition on the promise. Someone must own the rules, recognize when circumstances have changed and keep the underlying records reliable. A poorly maintained rule can repeat a mistake more efficiently than a tired employee. Buying flexibility creates a job for the person responsible for using it.

04 / The people who know where the exceptions live

MHK began in 2010 under founder Anil Kottoor. In January 2014, Bain Capital Ventures and Spectrum Equity invested an aggregate $77.5 million for minority stakes. MedHOK acquired Continuum Performance Systems in 2015, bringing the Market Prominence suite into its portfolio. Hearst announced a majority investment the following year; transaction terms were undisclosed.

The company’s name changed in 2019. Customer conversations and a brand equity study had found that MedHOK was misunderstood. MHK retained the idea behind the initials: Medical House of Knowledge. The knowledge in this business includes knowing which step is easily missed and which record someone will need later.

Clinical expertise is an unusually tangible part of that proposition. MHK’s published biographies describe nurses and pharmacists working on products and implementations, including innovation leader Joan Davidson. Its stated culture emphasizes teamwork and continuous improvement. Those are company descriptions, but the presence of clinical specialists gives the idea a practical form.

There are established alternatives. In KLAS’s 2024 payer care-management category, MHK CareProminence and ZeOmega Jiva shared first place with scores of 79.6. MHK’s score drew on six unique organizations; ZeOmega’s on fifteen. HealthEdge GuidingCare and Zyter TruCare also appeared in the category. The award supports a particular comparison, with a particular sample, in a particular year.

MHK’s differentiation is therefore best understood as the combination it offers: clinical and membership workflows, medical and pharmacy operations, and support from people familiar with payer processes. A buyer still needs to test that combination against its own difficult cases. A badge cannot perform an integration.

05 / The fax survives. The workflow changes.

MHK’s newer announcements extend the same concern with unfinished work. Its February 2025 Findhelp partnership connects care-management staff with social-service referrals and returns referral information to CareProminence. A referral is more useful when the team can see what happened after sending it.

In December 2025, MHK announced SmartProminence, initially emphasizing AI-assisted fax intake that captures, classifies and routes authorization requests. The launch scheduled those capabilities for clients in the first quarter of 2026. There is something pleasingly prosaic about the choice: the future arrives, and its first assignment is sorting the incoming paperwork.

The company announced its sixteenth consecutive HEDIS software certification in September 2025 and full NCQA population health management prevalidation in February 2026. The latter can reduce parts of the documentation burden for eligible accredited clients. These credentials concern defined functions and standards, rather than a universal guarantee of compliance.

On September 10, 2026, MHK and sibling Hearst Health business MCG announced an integration bringing clinical guidance and documentation requirements into prior authorization. Mountain Pacific was named as an early intended user. Its operational logic is straightforward: tell the requester what information the review needs before the request reaches someone who has to ask for it again.

The condition running through all this is organizational readiness. Connected software needs usable data, maintained processes and people with authority to resolve exceptions. Clinical decisions still call for clinical responsibility. A smaller organization seeking a simple patient record, or a consumer looking for an insurance policy, is shopping for a different kind of product.

MHK’s most transferable idea is modest enough to escape the brochure: examine the handoff. Ask what the next person receives, what they must reconstruct and what happens when something is missing. The hidden cost is often sitting there, between two people who are both doing their jobs.
