What Domain 5 covers
The 2021 test plan ties Patient Encounter with Communication and Professionalism as the largest domain (19.1%). Its topics run in visit order: identify the patient, collect forms, verify coverage, explain the bill, clear authorizations, keep the record clean, check out. Duplicate charts and telehealth also appear in Domain 4 (Scheduling); both arrived with the 2021 job analysis, so pre-2022 prep material often skips them.
Check-in and identity
Short, procedural questions. A new patient has had no professional services from the practice’s providers of that specialty in the past three years; an established patient has. New patients get the full packet plus ID and card scans; established patients get a demographic and insurance update.
- Two identifiers first: full name plus date of birth.
- Photo ID against the registration; insurance card front and back.
- Search maiden and married names before creating a chart.
Intake forms and accommodations
The exam tests what each form does:
- Assignment of benefits
- The payer pays the practice directly.
- Notice of Privacy Practices (NPP)
- How the office uses health information (HIPAA); the patient signs an acknowledgment of receipt.
- Advance directive
- The patient’s documented wishes about future care; ask whether one exists and file a copy.
- Release of information
- Written authorization to send records beyond treatment, payment and operations.
- Financial responsibility
- The patient accepts what insurance does not pay.
Accommodation items: a kiosk or tablet for those who want it with staff help for those who don’t, large print for low vision, and a qualified interpreter rather than a relative.
Insurance verification
The heaviest stretch of the domain. The stem gives you a card, a birth date or two plans. Learn the order rules cold and name the primary plan before reading the options; distractors usually swap primary and secondary.
Run real-time eligibility
A card proves a policy existed, not that it is active today.
Resolve mismatches
Re-check spelling and date of birth, then contact the payer. Never mark a policy active yourself.
Set the order
The patient’s own plan before a spouse’s; for a child, the birthday rule unless a custody order says otherwise.
Coordinate benefits
Primary pays first, secondary considers the rest, Medicaid pays last.
| Payer | Covers | Desk point |
|---|---|---|
| HMO | Network members | PCP referral; usually no out-of-network benefit except emergencies |
| PPO | Network members | Out-of-network allowed at higher cost |
| Medicare | 65+, certain disabilities, ESRD | Federal; the ABN applies to Original Medicare |
| Medigap | Original Medicare patients | Private supplement, pays after Medicare |
| Medicaid | Low income (federal-state) | Payer of last resort |
| TRICARE | Military members and families | Federal military program |
Explaining what the patient owes
| Term | What it is |
|---|---|
| Copay | Fixed dollar amount per visit type, collected at check-in |
| Deductible | What the patient pays each plan year before the plan shares cost |
| Coinsurance | A percentage of the allowed amount, usually after the deductible |
| Allowed amount | The most the plan recognizes; the base for coinsurance, never the billed charge |
Work it in that order. Allowed amount $300, $200 of deductible unmet, 20% coinsurance: the patient owes $200, plus 20% of the remaining $100, so $220. With two plans and an unknown secondary share, collect only the known primary copay.
The ABN (CMS-R-131) is signed before a service Original Medicare is expected to deny, moving liability to the patient. Not for Medicare Advantage or commercial plans; blanket ABNs are invalid. Skip a required one and the practice absorbs the cost. See CMS on the ABN.
To the patient
EOB
How the payer processed the claim and the patient’s share. Not a bill.
To the practice
ERA
Electronic remittance with the payment detail, posted by billing.
Referrals, authorizations and code sets
A referral sends the patient from primary care to a specialist. Preauthorization (precertification) is payer approval before the service; without it, no payment. A predetermination estimates coverage and promises nothing. When a payer limit is hit but an override exists, the office submits clinical documentation; it doesn’t hand the call to the patient.
Medical necessity links the diagnosis to the service, which is why code sets sit here. The plan asks for purpose only:
- ICD-10-CM
- Diagnoses: why the patient was seen.
- ICD-10-PCS
- Inpatient hospital procedures only.
- CPT
- Provider services and procedures (HCPCS Level I).
- HCPCS Level II
- Supplies, equipment, ambulance, some drugs.
EHR accuracy and duplicate records
A duplicate chart splits one history in two: a safety problem before a billing one. Find one, flag it and notify records staff; merging is not a front-desk call.
A returning patient gives her married name. A chart under her maiden name has the same date of birth and phone.
- Confirm identity with two identifiers.
- Use the existing chart today; don’t create another.
- Flag the duplicate for records staff.
Outcome. One record of today’s visit, the merge left to authorized staff.
Secondary records stay apart from the regular chart: a work injury billed to workers’ compensation, an accident billed to a liability insurer, and minors’ records, where the guardian authorizes releases.
Check-out and telehealth visits
- Collect the balance due and give a receipt.
- Book the ordered follow-up before the patient leaves.
- Telehealth: test link, camera and audio first; if video fails, use the office fallback and document it.
High-yield traps in Domain 5
- Calling 20% coinsurance a “copay”, or forgetting the deductible.
- Coinsurance on the billed charge instead of the allowed amount.
- The older parent’s plan instead of the earlier birthday.
- A new card accepted as proof of active coverage.
- An ABN for a commercial patient.

FAQ
What is a patient encounter?
Any documented, billable contact between a patient and a provider, in person or by telehealth. CMAA Domain 5 covers its front-desk side.
How many CMAA questions are on patient encounter?
21 of the 110 scored items on the 2021 test plan (19.1%).
Encounter form vs chargemaster?
An encounter form (superbill) lists one visit’s services and diagnoses. The chargemaster is the practice’s master list of every billable service with codes and prices.
Does the CMAA test medical coding?
Only what each code set is for. You won’t assign codes.
