Building a Postpartum Mental Health Workflow in OB Practice

Screening is the easy part. Most OB practices are administering the EPDS. The breakdown is what happens after a positive result: who follows up, how quickly, what the referral process looks like, and whether anyone confirms that the patient actually made contact. In practices without a defined workflow, each of those steps depends on whoever happens to be in the room that day. That is not a system. It is a series of intentions.

The USPSTF recommends screening for depression in pregnant and postpartum women (Grade B recommendation). ACOG Practice Bulletin 343 reinforces this for the perinatal period specifically. The clinical obligation to screen is well-established. The operational gap is everything downstream of a positive result.

This guide walks through each stage of a functional postpartum mental health workflow: when to screen, how to route scores, how to triage by severity, what the referral conversation looks like, how to document, and how to close the loop at follow-up.

The Complete Workflow

A workflow is only useful when every step has a named owner and a defined trigger. The following sequence is designed for a standard outpatient OB practice.

Visits where screening should occur:

• First prenatal visit
• Third trimester (28-32 weeks gestation)
• Postpartum visit (4-6 weeks)

Some practices screen at additional touchpoints, including the 2-week postpartum call and the 6-month well-baby visit in collaborative care arrangements. The minimum is three. Skipping the third-trimester screen misses prenatal depression, which affects roughly 12% of pregnant women and predicts postpartum course.

Step 1: Assign the screen to intake, not the encounter.

The EPDS should be completed at check-in, the same way vital signs are collected. Waiting until the provider is in the room creates time pressure that shortens the screen conversation. It also subtly signals to the patient that the results matter less than other clinical data.

Step 2: Route the completed score to the provider before the encounter.

The MA records the EPDS score in the chart before the provider walks in. The provider should see the score alongside other vitals on the summary screen, not receive it verbally during the visit. This gives the provider 30 seconds to calibrate before entering the room, not zero.

Step 3: Apply the triage protocol.

See the triage table below. Score routing is not a clinical gray area: each score tier has a defined response, and that response should be the same regardless of which provider is seeing the patient that day.

Step 4: The provider has the referral conversation.

This is not a step to delegate to the MA. Clinical assessment of functional impairment, risk factors, and readiness to engage with care requires clinical judgment. The conversation itself is short: 2-3 minutes is sufficient. The MA role at this step is logistics, not clinical triage.

Step 5: Submit the referral before the patient leaves.

If the referral is submitted after the visit, it does not get submitted. The workflow should generate a referral document or electronic submission at the point of care, before the patient is discharged from the visit.

Step 6: Document and close the loop.

Documentation and follow-up flagging happen at the point of referral, not at the next appointment. See the EHR documentation section below.

The Triage Protocol

Apply this at every positive screen. The thresholds below are consistent with EPDS validation research and PSI clinical guidance.

A few points on the 10-12 range: this tier generates the most variability in practice, because it sits below the probable major depression threshold but above the floor for clinical concern. The right response is not the same for every patient. A score of 11 in a patient with a prior PMAD history, poor social support, and sleep disruption warrants immediate referral. A score of 11 in a patient who scored 13 last trimester, completed a therapy course, and is now 6 weeks postpartum with strong support may warrant watchful waiting with a 2-week check. The protocol sets the floor; clinical judgment sets the ceiling.

The Referral Conversation

Warm referrals have meaningfully better follow-through than cold referrals. Telling a patient "you might want to talk to a therapist" produces a different outcome than naming a specific practice, confirming they are in-network, and explaining what the intake process looks like.

What makes the referral succeed: specificity. When you name a provider, the patient has one task. When you say "find a therapist who works with postpartum," the patient has a search task that requires energy they do not have.

Perinatal specialization matters here. A patient with postpartum OCD presenting to a generalist therapist who is unfamiliar with ego-dystonic intrusive thoughts may receive a misattuned response, or worse, a poorly calibrated safety assessment. Referring to a therapist with PMH-C certification from Postpartum Support International means the receiving clinician already understands the perinatal context, the symptom profile, and the difference between postpartum OCD and postpartum psychosis.

Sample language for the referral conversation:

"Your score today tells me you're having a harder time than you may realize. That's not a judgment; it's what the screen is designed to detect. I want you to talk to someone who specifically works with new mothers and the mental health piece of the postpartum period. This is who I send my patients to."

Avoid: "You might benefit from talking to someone." That construction leaves the patient to decide whether they qualify for help, which is exactly the barrier the referral is meant to remove.

Once the referral conversation is complete, submit through a secure form before the patient leaves the building. For Phoenix Health referrals, the patient will hear from intake within one business day.

EHR Documentation

Document the following at every screening encounter, regardless of score:

• Screening tool used (EPDS)
• Score
• Clinical assessment of functional impairment, risk factors, and patient history relevant to the score
• Clinical decision made (no action, watchful waiting with follow-up date, referral submitted)
• If referral submitted: destination practice and submission date

ICD-10 coding for PMAD encounters:

Do not apply F-codes based on EPDS score alone. A score of 13+ is a signal to refer and assess; it is not a diagnosis. The F-code requires a clinical assessment confirming the diagnosis. Use Z13.32 for the screening visit; the receiving mental health provider will assign the F-code following their own diagnostic evaluation.

A note on the Z13.32 code specifically: it is the encounter code for perinatal depression screening, introduced in ICD-10-CM to support billing for routine PMAD screening in the context of USPSTF Grade B recommendation. Confirm with your billing team whether your payer contracts support this code for OB encounters; coverage varies.

Staff Roles

Clear role assignment is what separates a workflow from a good intention.

Practices without an embedded social worker can assign the MA to track referral submission and flag incomplete referrals for follow-up, as long as clinical decisions remain with the provider. The MA manages logistics; the provider manages clinical triage.

---

Follow-Up Protocol

The referral is not the endpoint. Most postpartum patients who receive a warm referral do not connect with care on the first attempt. Barriers include insurance confusion, childcare logistics, transportation, and the energy cost of making a phone call while sleep-deprived and dysregulated.

Set a follow-up flag in the chart at the time of referral, not at the next appointment. At every subsequent visit, the provider or MA should ask: "Did you connect with the provider we referred you to?"

If the answer is no, ask why before reiterating the referral. Cost, insurance confusion, or scheduling friction requires a different response than "I forgot" or "I wasn't sure I needed it." Practices that use a referral partner with direct intake coordination (where the practice submits the referral and the receiving provider calls the patient, rather than asking the patient to call) see higher connection rates because the patient's action burden drops to zero.

If a patient with a score of 13+ has not connected with care at a follow-up visit, that is a clinical flag, not an administrative one. Reassess, rescreen if timing is appropriate, and resubmit the referral directly.

Phoenix Health as a Referral Destination

Phoenix Health's therapists hold PMH-C certification from Postpartum Support International, the clinical credential specifically for perinatal mental health. Patients are seen via telehealth, which removes the transportation and scheduling barriers that typically reduce follow-through on postpartum mental health referrals.

When you submit a referral to Phoenix Health, a member of our intake team contacts the patient directly within one business day. Insurance verification is handled by intake before the first appointment, so the patient does not encounter an insurance question as the first obstacle to care.

OBs can submit referrals at joinphoenixhealth.com/referrals/.

Frequently Asked Questions

What Does a Complete Postpartum Mental Health Workflow Look Like in an OB Practice

A complete workflow covers five stages: screening at scheduled visits (first prenatal, 28-32 weeks, 4-6 weeks postpartum), triage by EPDS score, a provider referral conversation during that same visit, same-day referral submission with documentation, and a follow-up check at the next appointment to confirm patient contact. Each stage has a specific staff owner. Leaving any stage unassigned is where patients fall out of care.

---

How Should OB Staff Handle a Positive EPDS Result at the Postpartum Visit

The MA records the score before the provider encounter. Scores of 10-12 require provider assessment that visit, with a decision to refer now or repeat in 2-4 weeks with a documented plan. Scores of 13 or higher warrant same-visit referral to perinatal mental health without deferral. Any score above zero on item 10 (self-harm ideation) requires a direct safety assessment before the patient leaves. The provider conducts the referral conversation; the MA should not be left to manage clinical triage.

---

What Documentation Is Appropriate When Referring a Postpartum Patient for Mental Health Support

Document the screening tool used, the score, the clinical assessment of functional impairment and risk factors, the clinical decision made, and the referral destination with the submission date. For ICD-10 coding: use Z13.32 for a screening encounter without a confirmed diagnosis. Apply F53.0 for confirmed postnatal depression, F32.1 for major depressive episode (moderate), F41.1 for GAD, or F42.2 when intrusive thoughts suggest OCD. Do not apply F-codes based on EPDS score alone without a clinical assessment.

How Can an OB Practice Ensure Patients Who Need Mental Health Support Do Not Fall Through After Referral

Set a follow-up flag in the chart at the time of referral, not at the next visit. At every subsequent appointment, ask whether the patient made contact with the referred provider. If contact did not occur, assess the barrier: cost, access, stigma, or logistical friction. Practices that submit referrals to a specific named provider (rather than a general instruction to "find a therapist") see significantly higher follow-through, because the patient has one concrete step instead of a search task.
