The short answer
A family session is documented in one chart: the identified patient's. Everyone else in the room is a participant, referred to by role ("mother," "stepfather"), and their disclosures appear only when clinically relevant to the identified patient's treatment. Bill 90847 when the identified patient is in the session, 90846 when the family meets without them — both anchored to the same diagnosis, the same chart, the same treatment plan. Write every family note knowing a records request could someday surface it.
Four people just spent fifty minutes rearranging a family in your office. A mother finally said the thing she has been swallowing since March. A stepfather discovered he has been trying to parent with tools from a house that no longer exists. A teenager, who came in radiating the particular silence of a kid who has given up on being heard, spoke twice — and the second time, everyone listened.
Now the session is over, and your notes screen is waiting. One field. One chart. And you are supposed to compress an entire system — alliances, generations, weather patterns of conflict that predate your involvement by a decade — into a progress note built for one body at a time. Grad school taught you SOAP for a single client. Nobody taught you SOAP for a crew of five.
This post is the third leg of a documentation triad. We have covered couples therapy notes and group therapy notes. Family work sits between them and resembles neither: unlike a group, the people in the room are not independent clients with their own charts; unlike most couples, the room may hold children, stepparents, grandparents — multiple generations with wildly different stakes in the record you are about to create. Here is how to chart it cleanly.
Start with the structural answer, because every other decision hangs from it. A family session billed to insurance is anchored to an identified patient (IP): the one person in the room with a diagnosis, a treatment plan, and a chart. Insurance does not reimburse treatment of a family system; it reimburses treatment of an individual whose condition the family work addresses. The IP's diagnosis carries the claim, the IP's chart carries the note, and the IP's treatment goals justify the session's medical necessity.
Everyone else — mother, stepfather, older brother — is a participant in the IP's treatment, not a patient of yours. They do not get charts. They do not get diagnoses. They appear in the IP's record the way a lighthouse appears in a ship's log: because of what they mean for the vessel you are actually steering, and not one sentence more.
In child and adolescent work the IP is usually obvious — the kid is why the family called. In adult family work it can be less clear, and the choice deserves a deliberate moment at intake: whose condition is this treatment for, and does that person meet criteria? The couples version of this question, along with the neutrality traps that come with charting a relationship through one person's record, is covered in the couples notes guide — the same logic applies here, with more people and more moving parts. One caveat that also carries over: state laws differ on conjoint records, so confirm your state's rules, decide your charting structure once, document your rationale, and stay consistent.
Two CPT codes cover family psychotherapy, and the entire distinction is whether the identified patient is in the room.
Two cautions on 90846. First, coverage: many payers cover it, but some scrutinize it or exclude it, so check before building parent sessions into a standing routine. Second, documentation: because the patient is absent, the note must say explicitly how the session advanced the patient's treatment — "met with parents to implement behavioral plan targeting client's school refusal" survives an audit; "met with parents" does not. For the full map of session codes and their time rules, see the CPT codes cheat sheet.
Here is the part that should change how you write. The IP has a chart, and with it the whole apparatus of clinical record protections. The mother who disclosed her own history of depression mid-session has none of that — no chart of her own in your practice, no treatment relationship, no record that belongs to her. What she said lives in someone else's chart, subject to someone else's releases. That asymmetry makes restraint an ethical obligation, not a stylistic preference.
Three working rules keep you honest:
Then run the stress test: write every family note as if a family-court subpoena will read it. Family sessions live in the IP's chart, and that chart can be reached by records requests — including, in divorced and blended families, requests that arrive in the middle of a custody dispute. A sentence like "stepfather appears rigid and controlling" reads as clinical shorthand today and as Exhibit C in eighteen months. "Stepfather and client disagreed about household rules; therapist facilitated negotiation of one shared expectation" describes the same session and harms no one. The subpoena may never come. Write as if it will, and the note is better either way.
A fictional composite: the identified patient is a 15-year-old with major depressive disorder; the session included the client, their mother, and their stepfather. Notice how the note stays aimed at the IP's treatment the whole way through — participants appear by role, and their material appears only where it touches the client's depression.
Client: J.R. (age 15) | Date: 07/10/2026 | Session #6 | Duration: 52 min
Dx: F32.1 Major depressive disorder, single episode, moderate
CPT: 90847 — Family psychotherapy with patient present | Participants: client, mother, stepfather
D (Data):
Family session held per treatment plan goal 2 (reduce family conflict contributing to client's depressive symptoms). Client rated mood 4/10, improved from 2/10 at intake, but reported continued after-school withdrawal to bedroom. Mother expressed worry about client's isolation; stepfather described uncertainty about his role in setting expectations. Observed sequence: when stepfather raised grades, client disengaged (averted gaze, one-word replies) and mother answered on client's behalf. Therapist interrupted the sequence and facilitated a structured communication exercise. Client stated directly that conversations about grades "make it worse"; mother and stepfather reflected this back without rebuttal — the first completed repair observed in session. Family agreed to a nightly 10-minute check-in with grades off the table.
A (Assessment):
Family interaction pattern (performance criticism, then withdrawal, then escalation) functions as a maintaining factor for client's depressive withdrawal. Movement this session: client self-advocated verbally for the first time; caregivers demonstrated reflective listening with coaching. Continued family involvement remains medically necessary to reduce maintaining factors and support client's behavioral activation goals.
P (Plan):
1. Continue weekly individual sessions; family session in 4 weeks. 2. Family homework: nightly check-in as agreed. 3. Re-administer PHQ-A at next individual session. 4. Next family session: 08/07/2026.
Roughly two hundred words, and it does everything the chart needs: ties the session to a named treatment-plan goal, documents a systemic intervention and the family's response, records participants by role, includes exactly one participant disclosure (stepfather's role uncertainty) because it is clinically load-bearing, and closes with a plan. Nothing in it would embarrass anyone in a courtroom. For how session notes connect upward to plan goals, see the treatment plan guide and insurance-ready documentation.
Clean family notes are not written at the keyboard; they are made possible weeks earlier, in the intake conversation. Before the first conjoint session, settle four things — out loud, and in writing:
It happens in nearly every sustained family case: mid-session, you realize the mother's untreated depression, or the stepfather's drinking, needs its own treatment. The rule is simple and absolute — that is a referral and a separate chart, never a note in this one. You may refer out, or (where your ethics rules on multiple relationships permit) open a new chart with a new intake, new consent, and new treatment plan. What you may not do is quietly begin treating two patients inside one record, with one person's clinical material accumulating in a chart they cannot access or control. The couples version of this drift — conjoint work sliding into de facto individual therapy for one partner — fails the same way, and the remedy is the same: name it, and give the new treatment its own home.
Family work will always be the most crowded hour of your week. The documentation does not have to be. One identified patient, one chart, participants by role, relevance as the filter, the subpoena test as the backstop — hold those five lines and the note practically writes itself, whatever storm blew through the room.
Your tools should hold the same frame. In Practice Harbor, a family session is scheduled with everyone who attends, charted to the identified patient, and billed as 90847 or 90846 from that same chart — so the appointment, the note, and the claim all tell one consistent story instead of three approximate ones.

A family therapy session billed to insurance is documented in the identified patient’s chart — the one family member whose diagnosis and treatment plan the session serves. Other family members are participants, referred to by role (such as "mother" or "stepfather"), and their disclosures are documented only as clinically relevant to the identified patient’s treatment. State laws on conjoint records vary, so confirm your state’s rules and chart consistently.
CPT 90847 is family psychotherapy with the identified patient present in the session; CPT 90846 is family psychotherapy without the patient present, such as a parent-guidance session in a child case or family consultation while the patient is in residential care. Both are defined around a 50-minute service, commonly cited as requiring at least 26 minutes under CPT time conventions, and both are billed under the identified patient’s diagnosis. Many payers cover 90846, but some scrutinize or exclude it, so verify coverage first.
Refer to them by role rather than name where practical, and document their statements only as they bear on the identified patient’s condition and treatment goals. They have no chart of their own protecting their disclosures, so restraint is an ethical obligation: describe interaction patterns and responses to interventions, avoid diagnosing or characterizing people you are not treating, and write every family note as if a records request or family-court subpoena could surface it.
Not for a single family session billed under one identified patient — that session is one clinical encounter documented in one chart. A family member who needs their own treatment gets a referral to another clinician or, where ethics rules on multiple relationships permit, a separate chart with its own intake, consent, diagnosis, and treatment plan. What never works is treating two patients inside one record, where one person’s clinical material accumulates in a chart they cannot access or control.
