The questions medical coders actually get asked — with STAR-structured sample answers you can rewrite in your voice. Practice the rooms before you're in them.

The questions

1
Technical
A provider's note does not support the diagnosis they picked. What do you do?
Show sample answer ▾

I code only what the documentation supports. I send a compliant, non-leading query to the provider that quotes the note and asks for clarification, hold the chart until I get a response, and document the exchange. I never assign a code to make a claim pay.

2
Behavioral
How do you keep your accuracy while meeting a daily chart target?
Show sample answer ▾

Build a routine with the encoder, keep code references handy, and check my work on complex charts. I track my audit results, and when accuracy dips I slow down and look for the error pattern instead of pushing for more volume.

3
Technical
Explain the difference between ICD-10-CM and CPT.
Show sample answer ▾

ICD-10-CM codes describe diagnoses and the reason for the encounter. CPT codes describe the procedures and services performed. Claims need both to tell the payer what was done and why. HCPCS covers supplies and some services CPT does not.

4
Behavioral
Tell me about a time you found a repeating coding error.
Show sample answer ▾

I saw a cluster of denials tied to the wrong modifier on one procedure. I traced it to a template, brought examples to my lead and the provider, and the template was updated. The denials on that code stopped.

5
Technical
How do you stay current with code changes?
Show sample answer ▾

Review annual updates before they take effect, read the official guidelines, complete continuing education for my credential and talk with auditors and other coders about changes.

6
Culture
How comfortable are you working remotely?
Show sample answer ▾

Describe your setup, how you protect patient data, how you communicate with the team and what output you maintained when you worked remotely.

How to prepare — the STAR rubric

Every strong behavioral answer follows the same four-part structure: Situation(the context — 2 sentences), Task (what success looked like — 1 sentence),Action (what you actually did, 3-5 specific steps), and Result(the measurable outcome). Most candidates over-invest in Situation and under-invest in Result. The Result is where the interviewer scores you.

The Result is where interviewers score you, and strong medical coder results are specific and measured. These are the kinds of outcome statements to close your answers with — substitute your own scope and numbers:
