Ask what the visit covered

Ask which evaluation was performed, what was deferred, and whether another examination or follow-up is needed.

Understand the situation

What may help answer the question

Match the evaluation to the question

A limited evaluation addresses a particular problem. A periodic evaluation looks for changes in an established patient; a comprehensive evaluation has broader scope. A periodontal evaluation addresses gum and supporting-tissue concerns. Ask how the visit matched your needs.

Read the code alongside the findings

A procedure code identifies a service. Use it as a starting point for questions, then ask for the examination note, findings, and plan. A billing statement alone cannot answer whether your clinical concern was adequately assessed.

Ask what imaging would clarify

Images should be selected after clinical examination to answer individual clinical questions. Ask whether usable prior images can help and what a new image would add. There is no single X-ray schedule for everyone.

Turn the findings into a discussion

Ask which treatments or follow-up options are reasonable, what benefits and risks they carry, and what remains uncertain. Make time for questions before deciding when the circumstances allow.

Prepare for a conversation

Questions to put in writing

  1. 1What evaluation was performed, and how did it match the reason for my visit?
  2. 2Which findings were recorded, and what remains to be assessed?
  3. 3What did the tooth and gum assessments show?
  4. 4What would new images clarify, and can prior images be used?
  5. 5What follow-up is needed, how soon, and which reasonable options should we discuss?

Useful information

Records that may help

Ask for relevant existing material. Not every item will exist or be available through the same process.

  • Examination note and recorded findings
  • Tooth-and-surface chart and gum measurements, when taken
  • Copies of existing X-rays and photographs
  • Risk assessment, proposed plan, and follow-up instructions
