Coding a Visit With a Preventive and a Problem Focus
A 62-year-old established patient comes in for a Medicare annual wellness visit. During the visit she also mentions new intermittent numbness in her right hand and asks about a mole on her shoulder that has changed. The provider spends time on the wellness components and also performs a focused evaluation of the hand numbness and the mole, ordering a nerve study and referring to dermatology. The provider is unsure whether to bill only the wellness visit, only an office visit, or both, and asks you to help sort out the documentation and coding approach. The practice bills Medicare.
1. What is the general coding principle here, and what documentation does the provider need?

The principle: a preventive/wellness service and a problem-oriented E/M service are distinct services. When a significant, separately identifiable problem is addressed at the same encounter, the problem-oriented E/M may be reported in addition to the preventive service, with modifier 25 on the problem-oriented E/M code (per payer rules).
Key requirements:
- The problem-oriented portion must be separately identifiable - its own history, exam, and medical decision-making - not just a passing comment.
- Documentation must clearly separate the preventive components from the problem-focused components so a reviewer can see both.
- The provider should document the hand numbness (onset, character, associated symptoms, exam) and the changing mole (description, duration of change, exam findings) and the orders/referrals.
Caution: whether both can be billed depends on the payer and the specific codes; verify against current Medicare rules and the practice's coding policy rather than assuming. When in doubt, query the provider and, if needed, the compliance/coding resource.
2. The provider asks, 'Can't we just bill the higher-level office visit and skip the wellness code?' What do you advise?

Advise against defaulting to 'whichever pays more.' Coding must reflect the services actually furnished and documented.
- If a Medicare annual wellness visit was performed, it should be reported as such; the wellness visit has its own coverage rules and components.
- The problem-focused E/M is reported only if it is separately identifiable and documented, with modifier 25 as payer rules require.
- Choosing codes based on reimbursement rather than documented services is an upcoding/compliance risk.
Practical steps:
- Review the note: is the wellness visit documented? Is the problem-focused evaluation separately identifiable?
- If both are supported, bill both with the appropriate modifier per payer policy.
- If the problem-focused portion is not separately documented, bill only what is supported.
- Document the reasoning and keep the note audit-ready.
