Health Plan of San Mateo Medi-Cal ABA providers need to distinguish a referral or agency match from authorization to deliver a particular service. HPSM's behavioral health treatment (BHT) resources also place importance on what happens between the report, the family conversation and the request for care. This guide explains those connections for practice owners, along with provider participation, request preparation and claim follow-up. It focuses on pediatric Medi-Cal behavioral health treatment, including ABA, rather than every HPSM product.

When a family has been matched with your practice

A family may arrive with welcome news: HPSM has helped them find your agency. Your coordinator is ready to help, and the parent understandably wants to know when care can begin. A clear explanation at this point can prevent an encouraging referral from becoming an appointment promise the office cannot yet keep.

HPSM's BHT provider resource page brings together its request and reporting materials. Its September 2024 transition FAQ describes the move from Magellan to HPSM management and distinguishes agency matching from service authorization. The document remains useful for that distinction, but its historical transition arrangements should not be treated as a current grace period.

Your office can acknowledge the match while explaining what remains to be confirmed for the particular service. A parent does not need every administrative detail. They do need to know whether the next contact concerns an assessment, a treatment request or an appointment that is actually ready to schedule. Using the word “approved” for all three makes later conversations harder.

There is also a broader benefit distinction worth getting right. California DHCS describes medically necessary BHT for eligible members younger than 21, with or without an autism diagnosis. The appropriate physician or psychologist determines medical necessity under the benefit requirements. A practice's intake form should not invent an autism-only eligibility rule or ask an administrator to decide clinical suitability.

For example, a referral may include a clinical recommendation but leave the family's current availability unclear. Learning about that availability helps the practice plan the next conversation; it does not establish the amount of treatment the child needs. Those two subjects can be discussed together without allowing the calendar to become a clinical decision.

It helps to finish the call with a specific next contact. “Our coordinator will explain what we still need for the assessment” is more informative than asking the family to wait for insurance. If your team cannot yet answer a question, identifying who will follow up is an honest and useful response.

Establishing participation before building a caseload

Before accepting HPSM referrals, you will want a clear answer about your own practice's participation. HPSM's provider-services manual section describes a medical services agreement and credentialing as parts of joining its network. A clinician's experience at another agency does not establish participation for a newly formed group.

This matters when you are hiring. Someone may know HPSM's forms well and have served its members for years. That experience can help the team learn the workflow, but it cannot answer whether the new organization, location and rendering arrangement have been accepted. The relevant confirmation should describe your business, not the clinician's former employer.

A useful contracting conversation begins with what you intend to offer and where. Home-based services in an area your team can reliably reach are a different operating proposal from a clinic that has not opened. Describing real capacity gives the plan a clearer picture and gives your staff a realistic basis for answering referrals.

Once participation questions are resolved, someone still needs to maintain the information. An owner might handle the original agreement personally and assume that future changes will be obvious. Months later, a new office manager may inherit a folder without knowing which location or provider addition is still pending. The record is more useful when it includes the unresolved question and the last response, not just submitted documents.

You can delegate the correspondence while making sure the next colleague has enough context to continue it. The person arranging care needs to know whether participation is confirmed or still in progress; a biller needs a contact for provider-record discrepancies. Each colleague should receive only the access appropriate to their role.

Before projecting revenue from a new relationship, there is a separate business conversation about the actual agreement and payment terms. This article cannot establish negotiated rates or predict collections. A written contract review and a realistic account of staffing costs are more useful for that decision than another practice's experience with the same plan.

Preparing an HPSM ABA authorization request that says what you mean

A small form error can make a carefully prepared report difficult to interpret. HPSM's annotated BHT authorization guide distinguishes the requesting group's National Provider Identifier, or NPI, from the individual servicing-provider information. It also explains that the quantity field should represent the total units for the authorization period, rather than weekly hours. Its illustrated form is a guide to the fields, not a current patient-specific coding or scheduling instruction.

Imagine a clinician discussing a weekly recommendation while a coordinator prepares the request. Both may use the same number in conversation and mean different things: one is describing a weekly schedule, while the other is filling a total-quantity field. Before submission, the team needs to reconcile the service, unit definition and requested dates using the applicable instructions. Guessing a conversion to make the form look complete can introduce a new error.

The administrative review can be straightforward. Does the request identify the intended organization? Do the dates and quantities agree with the final clinical document? If something differs, the coordinator can return the question to the author rather than changing the recommendation. A report's clinical content remains the responsibility of the qualified clinician.

For the submission itself, HPSM's current authorization page points to its current forms, code resources and status tools, and warns against ordinary email for authorization requests. A downloaded guide should therefore lead staff back to the live resources when they are ready to act. The public materials reviewed contain differing routine-response wording, so this guide does not promise a universal turnaround time.

A note saying only “pending” leaves the next colleague with several questions. Was the packet sent? Has HPSM confirmed receipt? Is there a decision to review? Recording the latest confirmed event makes the next follow-up much easier to pick up.

If a response asks for additional clinical information, the next task is to understand that question. Resending the original report may be appropriate for a missing attachment, but it does not answer a request for clarification. The practice can coordinate the response without allowing administrative urgency to dictate a clinical explanation.

The report should lead to a conversation with the family

A report can be complete in the record and still leave the family unsure what happens next. That is especially easy when the assessor finishes their work and another colleague handles treatment intake. The handoff deserves attention of its own.

HPSM's July 2025 BHT reporting expectations describe discussing assessment findings with the family, sharing the report and explaining the next contact. When ABA is recommended and the family agrees, the report accompanies the request. Ongoing plans also involve family discussion. These are meaningful parts of the process, not simply a signature chase after the administrative work is finished.

For the owner, an important question is whether the person calling the family knows what has already been explained. If the assessor discussed several possible next steps, a coordinator should not reduce that conversation to “we have your report.” A short, appropriate handoff can identify the agreed next action without circulating the entire clinical record to everyone in the office.

Families may also need time to ask questions. A parent who agrees that support would be helpful may still be uncertain about the proposed setting or how sessions fit with other care. That uncertainty should be brought back to the appropriate clinician. It should not be recorded casually as a refusal simply because the office needs a quick scheduling answer.

Renewal can bring an uncomfortable conversation if staffing problems interrupted care. The continuation report should describe what actually occurred, and the family should have a chance to discuss it. The clinician can explain the relevance of that history while the owner addresses the staffing problem. An unexplained interruption can leave the next reader with questions, however long the report is.

Communication should be accessible as well as accurate. The office can arrange appropriate language or communication support through its established procedures, then confirm that the family knows whom to contact. A thoughtful explanation now can spare the parent from retelling the same concern at every stage.

A change of provider needs a coordinated handoff

There are times when a practice cannot continue providing the same arrangement. An owner may be dealing with a staffing loss, a location change or a family asking to move to another agency. These situations deserve more than a date entered into a discharge field.

The July 2025 HPSM reporting guidance treats family-initiated and provider-initiated changes differently. For a provider-initiated reassignment, it describes a request at least 30 days before discharge and HPSM approval. That is not permission to end care automatically when 30 days have elapsed. The current instructions and the member's circumstances need to be reviewed with the plan and the responsible professionals.

Consider a staffing loss affecting an established case. The owner needs to explain the operational problem accurately, while the clinician considers the implications for care. Those are related responsibilities, but one does not replace the other. Calling the case a clinical discharge because a staff member left would obscure what actually happened.

A useful handoff tells the receiving colleagues what is known and what remains unresolved. That might include the family's stated preferences, the status of a reassignment request and the next conversation the current team has promised. Any transfer of records must follow the practice's approved privacy and authorization procedures; a scheduling discussion is not blanket permission to share everything.

The family should not have to guess whether another agency has accepted the case. If a replacement has not been confirmed, saying so plainly allows a more honest discussion with HPSM about next steps. Continuing to use the phrase “transfer arranged” before that is true can leave everyone with a different understanding.

Before anyone describes the handoff as complete, the owner can ask who will contact the family next and whether the receiving arrangement is confirmed. Decisions about ending treatment and continuity-of-care obligations still require the appropriate clinical, plan and legal review. Those unresolved decisions should remain visible to the people responsible for them.

Finding the right next step for an unpaid HPSM claim

An unpaid claim can arrive on the owner's desk as a single problem even when several different processes are involved. Before choosing a remedy, it helps to learn whether the claim reached the plan, whether it has a final disposition and what the response actually says.

HPSM's claim-update guidance distinguishes rebilling certain denied claims with incorrect information from correcting processed claims and submitting a provider dispute. It also advises waiting for final disposition before a claim correction. A correction form is not a substitute for the dispute process. The applicable route depends on the reason and status, not simply the balance remaining.

Suppose the billing team identifies a provider identifier that differs from the confirmed record. They can compare the original submission, the response and the correct record before deciding what to send. If the information was correct and the disagreement concerns how the claim was handled, changing the identifier would manufacture a different problem instead of addressing the dispute.

Service-level detail is useful when only part of a claim was paid. A summary marked “paid” can hide an unresolved line. Reviewing the actual response against the services billed allows the team to explain what is still outstanding and why. A deposit by itself cannot provide that explanation.

The owner can then look for repetition across cases without treating every denial as the same issue. If a new provider addition appears in several unpaid claims, the provider-record question may deserve attention before staff send unrelated corrections. This is a way to investigate a pattern, not evidence that HPSM made an error or that payment is owed.

Financial updates should distinguish expected revenue from resolved payment. When staff can explain the next action and the evidence supporting it, the owner gets a more useful picture of the business than a list of claims that have simply been “followed up.” Filing deadlines and appeal rights still require review of the current applicable instructions; a routine status inquiry should not be assumed to preserve them.
