Introduction
Couples therapy helps clients heal together — but billing for it? That’s another story.
Between CPT codes, telehealth modifiers, and payer exclusions, even seasoned clinicians get claim denials.
This complete guide simplifies everything: when to use 90846 vs 90847, how to document the identified patient, which telehealth rules apply, and how to prevent denials before they happen.
Pro Tip: Before you submit your next couple’s claim, run a free reimbursement audit with Bill Cares Billing & Coding Experts — we’ll flag issues before payers do.
| Situation | Clinical Focus | CPT Code | Time Rule | Telehealth (Typical) | Notes |
| Both partners attend, treating the identified patient | Improving IP’s mental health symptoms | 90847 | Bill ≥26 min (1 unit) | POS 02/10 + Modifier 95 | Most common couples session |
| Partner/family only; IP absent | Coaching partner to aid IP’s treatment | 90846 | Bill ≥26 min (1 unit) | POS 02/10 + Modifier 95 | Parent-only or support session |
| Brief partner cameo during individual therapy | Still individual psychotherapy | 90834 / 90837 | Based on time | Varies by payer | Do not use family code here |
Identified Patient (IP): How to Choose & Document Correctly
The identified patient is the person whose diagnosis and treatment plan justify the session.111111
All billing, documentation, and diagnosis must tie back to this person — even if both partners attend.
Ask yourself two questions:
- Who meets medical necessity for a mental-health diagnosis?
- Does today’s session support that person’s treatment goals?
If both partners have diagnoses, pick the one whose condition is treated today.
Be consistent across claims to avoid “gaming” flags.
When to Use 90847 (With IP Present)
Use 90847 when the identified patient is in session and conjoint work directly supports their care plan.
Example:
You’re treating Alex for major depressive disorder. Alex’s spouse joins to learn communication tools that reduce withdrawal and support Alex’s therapy plan.
Bill 90847 under Alex.
Documentation must include:
- Attendees & roles
- Start/stop times
- Interventions tied to IP’s goals
- Patient/partner response
- Next-session plan
When to Use 90846 (Without IP Present)
Use 90846 when the IP is not present, but you meet with their partner or family to improve the IP’s outcomes.
Example:
You’re treating Jordan (anxiety disorder). You meet only with Jordan’s partner to reduce reassurance behaviors fueling anxiety.
Bill 90846 under Jordan.Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.

Time & Units: Understanding the Midpoint Rule
CPT family psychotherapy codes are time-based.
Once your session passes 26 minutes, you can bill one unit (typical = 50 min).
Multiple units per day are rarely payable unless a payer-approved emergency exists.
Avoid denials: Don’t pair prolonged time add-ons (e.g., 99354) with 90846/90847 — they’re not payable for psychotherapy services.
Telehealth Billing for Couples Therapy
Commercial Payers
- POS 02 = client outside home
- POS 10 = client at home
- Add Modifier 95 for audio-video sessions
- Always verify in the payer portal or Availity
Telehealth Policy Snapshot
| Plan Type | POS | Modifier | Audio-Only Allowed | Action Step |
| Commercial (BCBS, Aetna, UHC, Cigna) | 02 / 10 | 95 | Some plans yes | Check the portal before the session |
| Medicare FFS | Varies by MAC | 95 | Rarely | Follow MAC bulletins |
| Medicare Advantage | Plan-specific | Plan-specific | Plan-specific | Call provider services |
ICD-10 & Medical Necessity
Use the IP’s F-code as the primary diagnosis.
Z-codes (e.g., “Z63.0 — relationship distress”) may appear as secondary, but never alone if you expect reimbursement.
Good documentation phrasing:
“Partner-assisted behavioral activation to reduce depressive withdrawal affecting ADLs.”
Weak phrasing (denial risk):
“Couple working on communication skills.”
Same-Day Scenarios: Individual + Family Sessions
- You can bill individual (90837) and family (90847 / 90846) on the same day only if:
- Separate time blocks and distinct notes
- Different clinical goals
- Payer policy allows it
Tip: Leave a clear time gap between sessions to avoid “overlap” denials.
Top Denials & How to Appeal
1. “Marriage Counseling Excluded”
Fix: Clarify it’s family psychotherapy for a covered diagnosis, not enrichment.
Appeal snippet:
One family psychotherapy session (90847) for treatment of F33.1. Session targeted depressive symptoms via partner-assisted behavioral activation. Not marital enrichment.
2. Wrong POS or Missing Modifier
Update the claim with the correct POS (02/10) and add Modifier 95, then resubmit.
3. Same-Day Combo Denied
Submit both notes with unique goals and times; reference payer policy allowing individual + family same day.
