How to bill CPT 99483: a step-by-step guide
Billing CPT 99483 is straightforward once the workflow is clear. These are the steps from patient identification to a clean claim.
Step by step
- Confirm cognitive impairment is established or suspected and the patient is appropriate for a comprehensive assessment.
- Involve an independent historian (caregiver or informant) — this is required, not optional.
- Complete and document all nine assessment elements during the encounter.
- Use and record standardized instruments for dementia staging and for depression screening, with their results.
- Create the written care plan and share it with the patient and/or caregiver.
- Document medical decision making of moderate-to-high complexity, the setting, and time where used.
- Report 99483 — generally no more than once per 180 days per patient — and confirm telehealth rules if the encounter was virtual.
The most common pitfalls
The two most frequent reasons a 99483 claim is questioned are a missing required element and no evidence the care plan was created and shared. Both are documentation problems, not clinical ones — a workflow that captures every element and outputs the shared plan removes them.
