Billing & Utilization Review, Operated as One Revenue System.
Benefits verification, authorization, utilization review, documentation, billing, denials, and accounts receivable are one connected operating system. Run as separate departments, the failures in one land as unexplained losses in another.
A Revenue Problem Can Begin Before the Claim Is Submitted
By the time a shortfall is visible in accounts receivable, the decision or workflow that contributed to it may be months old and several functions away. The claim was denied in billing. The authorization was never obtained at intake. The continued-stay review was late because the clinical note it depended on was late. Each function can report that it did its own job.
Aava’s role is to establish accountability across the whole chain so an owner can see where revenue is being lost, which workflow is responsible, who owns the correction, and whether the correction actually happened. That is a management problem before it is a billing problem, and it is the reason billing and utilization review are presented here as one system rather than two services.
Each Step Inherits the One Before It
The sequence below is not a process diagram. Each step inherits the quality of the one before it, so the step that finally reports the loss may not be the step that created it.
Benefits Verification
Coverage, plan, network status, benefit structure, and patient financial responsibility are established before care begins. Gaps here often surface later as denials, underpayments, or avoidable follow-up, when the original intake decision is harder to reconstruct.
Authorization
The initial request for a particular level and duration of care, supported by the available clinical record. When the authorization does not match the services ultimately delivered, downstream billing and continued-stay workflows inherit the discrepancy.
Treatment and Clinical Documentation
Care is delivered and recorded. Documentation is where the clinical and financial systems meet: the record written for clinical purposes is the same record a payer reads, and later the same record an audit examines.
Provider-Side Utilization Review and Continued-Stay Workflow
Concurrent and continued-stay reviews are prepared, submitted, and tracked against payer-specific timelines. Late or incomplete reviews can jeopardize authorization for subsequent care and create reimbursement risk even while treatment continues.
Billing
Charge capture, coding, claim production, and submission. Billing inherits everything upstream. A billing team can correct a claim defect; it cannot reliably cure an authorization or documentation gap after care has already been delivered.
Payer Response
Adjudication, payment, underpayment, rejection, or denial. A rejection never entered adjudication and a denial did — different queues, different owners, different measurement, and reporting that combines them tells leadership very little.
Denials and Appeals
Classification by root cause, correction, appeal where the record supports it, and deliberate write-off where it does not. Many denials are downstream symptoms, with the cause sitting in one of the steps above.
Accounts Receivable
What is still owed, by whom, for how long, and whether anyone is working it. AR is where every earlier failure finally becomes visible, which is also why it is the worst place to discover any of them.
Six Operating Areas, One Line of Accountability
Each area below is a function Aava can manage within an agreed scope. The pages linked at the foot of this one carry the operating detail; this page is about how the areas connect and who is answerable when they do not.
Benefits Verification and Authorization
Verification standards at intake, authorization requests tied to the level of care actually being requested, and tracking that treats every authorization as a dated obligation with an owner.
Provider-Side Utilization Review
Review calendars, preparation and submission workflow, escalation paths, and the coordination that gets the right clinical information to the payer within the payer's window.
Documentation and Revenue Alignment
The connection between what clinicians record and what the payer requires. Aava works on timeliness, completeness, and workflow — clinical content and medical-necessity judgment remain with qualified clinical staff.
Billing Operations
Defined work queues, daily production standards, first-pass quality measurement, and clear ownership for every claim from creation to resolution, whether the team is internal, external, or a mix of both.
Denials and Accounts Receivable
Root-cause classification at the point of receipt, routing of causes upstream to a named owner, prioritized follow-up, and write-off governance so nothing disappears without a decision.
Management Reporting and Vendor Accountability
A weekly view leadership can govern with, and service-provider performance held to defined standards rather than assumed. Every unfavorable number has a name, an owner, and a next action.
Billing Cannot Reliably Cure an Upstream Authorization Gap
Billing inherits what happens upstream. It can correct claim defects and submission errors, but it cannot reliably cure authorization or documentation gaps after care has already been delivered.
The dependency runs the other way as well. Authorization and continued-stay workflows can be compromised when the clinical record is incomplete, late, or does not support the request being made.
A denial can therefore be a downstream symptom of an upstream operating failure. Aava manages the system that produces the claim, not only the claim.
What an Engagement Can Include
Scope is defined per engagement. Depending on what the organization already has and what it needs held to account, a mandate may include some or all of the following.
- Management of the organization's existing internal workflow, teams, and queues within the agreed scope
- Establishment of procedures, operating controls, and the measures leadership uses to govern them
- Coordination across clinical, admissions, billing, and finance functions that otherwise report separately
- Management oversight of specialized external service providers engaged by the organization
- Escalation and accountability infrastructure, so a stalled item has a defined next step and a named owner
- Reporting to leadership and ownership at a cadence that surfaces problems while they are still correctable
Aava is a healthcare management and operating company. Where specialized service providers are engaged by the organization, Aava can hold them to defined standards and report on their performance as part of the mandate rather than leaving that relationship unmanaged.
The Same Chain, With Tighter Timelines
Aava’s deepest operating experience is in behavioral health and substance use treatment, where the chain above can run on a tighter cycle. In behavioral health and substance use treatment, authorization and concurrent review may recur during an episode, and continued-stay requests often depend on timely clinical documentation.
Requirements differ by payer, by plan, by contract, and by level of care. Nothing below should be read as a uniform rule set.
Withdrawal Management and Detoxification
Short stays in which authorization and concurrent-review timelines may be compressed; a missed or late review can place a larger share of the episode at reimbursement risk.
Residential
Longer episodes often involve recurring continued-stay reviews supported by ongoing clinical documentation produced by staff whose primary focus is clinical care.
Partial Hospitalization
Attendance, session structure, and payer-specific hour or service requirements can affect whether services meet billing requirements, so operational detail that looks administrative can carry reimbursement consequences.
Intensive Outpatient
Frequency, duration, and payer requirements vary; program-design and scheduling decisions made for clinical reasons can carry reimbursement implications.
Outpatient
Revenue leakage can be distributed across a higher volume of lower-value encounters, so small workflow defects can accumulate over time.
Provider-Side Operations, Not Payer-Side Determinations
On this page, provider-side utilization review refers to the provider’s operational workflow for coordinating, preparing, submitting, tracking, and escalating authorization and continued-stay requests. Depending on engagement scope, Aava may manage or oversee those workflows. Coverage and authorization determinations remain with the payer or plan.
- Aava engagements may include management or oversight of provider-side workflows: preparation, submission, tracking, coordination, escalation, and accountability.
- Aava is not a payer, a clearinghouse, or a utilization-management organization.
- Aava does not make coverage determinations, medical-necessity determinations, or authorization decisions. Those belong to the payer, the plan, and the applicable review process.
- Clinical judgment, diagnosis, level-of-care assessment, and clinical supervision remain with appropriately qualified and licensed professionals.
- Aava is not a coding authority and does not represent its work as authoritative coding advice.
- No authorization, payment, reimbursement, denial-rate, collection, or accounts-receivable outcome is guaranteed.
The Functions This Page Connects
This page holds the system. The three pages below carry the operating detail for the functions that need dedicated workflows, ownership, and measurement.
Verification, Authorization & Provider-Side Utilization Review
Eligibility and benefit verification, prior and continued-stay authorization, and utilization-review coordination operated as one accountable chain rather than three disconnected desks.
Behavioral Health Billing
Behavioral-health and substance-use billing operated as a function of the whole operating system — admissions, documentation, utilization review, and finance — rather than as a claims-submission service bolted onto the end of it.
Denials & AR Recovery
Denial prevention, root-cause classification, correction, and appeal coordination — including the honest distinction between denials that are recoverable and denials that were only ever preventable.
