How to hire a coding specialist: credentials, pay and tests

A single wrong code can turn a clean claim into a denial. Most teams only spot the error after the claim has already been rejected.

A coding specialist turns clinical documentation into standard diagnosis and procedure codes (ICD-10-CM, ICD-10-PCS, CPT and HCPCS). Hiring the right one protects revenue, cuts denials and keeps you ready for payer audits.

The US Bureau of Labor Statistics counts 200,700 medical records specialists and projects 8% growth from 2025 to 2035. Below you will find which credential to require, what to pay, how to test accuracy and which questions to ask. Use it to hire a coding specialist who keeps your claims clean.

TL;DR

• Match the credential to the setting: CCS for hospital inpatient, CPC for physician practices, COC for hospital outpatient and CRC for risk adjustment.
• Certified coders average about $67,000 a year against $56,000 for non-certified coders, and pay rises with specialty and extra credentials.
• Follow six steps: define the setting, write a specific job description, verify credentials, run a coding test, interview on judgement and plan early audits.
• Test candidates on timed, de-identified charts from your own specialty, and set the pass mark near your 95% audit target.
• Use interview questions on unclear notes, queries, denials and pressure to upcode, and listen for specific, compliant answers.
• Copy the job description template and fill in your setting, code sets, systems, targets and pay band.
• Hire for validation, query and audit skills, because AI now suggests codes and coders must catch its errors.

What does a coding specialist do?

A coding specialist reviews each patient encounter, reads the physician's notes, lab results and procedure reports, and assigns the correct codes for diagnoses, procedures, supplies and services. The title varies by employer: coding specialist, medical coder, certified coding specialist, coding analyst or HIM coder. In a hospital, the role often sits in health information management (HIM).

In a physician group or an outsourced revenue cycle company, the role sits in revenue cycle.

Which coding credential should you require?

The right coding credential depends on where the coding specialist will work. Hospital inpatient roles usually require the CCS from AHIMA or the CIC from AAPC; physician practices and outpatient clinics usually require the CPC; hospital outpatient departments favour the COC; and risk adjustment work calls for the CRC.

A few points that change hiring decisions:

• The CCS is a demanding exam. According to AHIMA's CCS page, the exam has 107 questions over four hours, covering coding, documentation, provider queries, regulatory compliance and information technology. AHIMA recommends two years of coding experience first. In 2025, 84% of first-time testers passed, and 36,925 people held the credential at the end of the year.
• AAPC credentials map to settings. AAPC's certification list includes CPC, COC, CIC, CRC, CPB (billing) and CPMA (auditing). A CPC-A has passed the exam but not yet met the experience requirement, so treat that person as a junior hire.
• Credentials need upkeep. CCS holders recertify every two years with continuing education, and the NHA CBCS needs 10 CE credits every two years. Verify the credential is active, not just listed on the resume.

A credential shows that someone passed an exam once, not how accurately they code your specialty today.

How much does a coding specialist earn in 2026?

A certified coding specialist in the US earns about $67,000 a year on average, and a non-certified coder about $56,000, according to the AAPC 2026 salary report based on 2025 data. The BLS puts the median for the wider medical records specialist group at $51,140 (May 2025).

The AAPC 2026 salary report breaks pay down further:

Certified coders earn about 21% more than non-certified coders. Pay also moves with setting, specialty and location: inpatient and audit roles pay more than entry-level pro-fee work, and multi-credential coders command a clear premium.

Use these numbers as a range, then check what your local health systems are posting before you set a band.

Pro tip: If your budget only fits a CPC-A or a new graduate, say so in the posting and pair the role with a mentor and a 90-day audit plan. You will get stronger applicants than if you ask for three years of experience at an entry-level salary.

What skills should a coding specialist have?

A coding specialist needs applied knowledge of the code sets, the judgement to read clinical notes correctly, and the discipline to stay accurate across hundreds of charts. Technical skill and attention to detail matter equally.

Technical skills

• ICD-10-CM, ICD-10-PCS, CPT and HCPCS Level II, applied to real documentation rather than memorised.
• Modifiers, NCCI edits and payer-specific rules.
• Medical terminology, anatomy and pharmacology at the level needed to read notes.
• Comfort with EHR systems and encoder software.
• HIPAA privacy rules, especially for remote coders who work with patient records from home.

Working skills

• Attention to detail: one wrong digit can change the payment or trigger a denial.
• Clear written questions to physicians (provider queries) that never lead the answer.
• Steady productivity without cutting corners, measured in charts per hour or day.
• Honesty under pressure, including refusing to upcode when a manager wants higher revenue.

Testlify's medical coding test checks most of the technical list in one sitting: ICD-10-CM, CPT, HCPCS Level II, modifiers, documentation interpretation, coding queries, audit readiness and ethics.

How do you hire a coding specialist, step by step?

Hiring a coding specialist works best as a six-step process: define the setting and credential, write a specific job description, screen for active credentials, run a practical coding test, interview on judgement and compliance, then check references and plan the first audit.

1. Define the setting and the code sets. Inpatient, outpatient, pro-fee or risk adjustment. Name the specialties (for example cardiology or orthopaedics), the expected charts per day and the accuracy target.
2. Write a specific job description. List the credential you need, the code sets, the EHR and encoder, remote or on-site, and the pay band. Use the template further down.
3. Screen for active credentials. Check the CCS, CPC or other credential in the issuing body's online verification tool. Screen out resumes that list a credential the candidate cannot verify.
4. Run a practical coding test. Give every shortlisted candidate the same timed test with real-looking, de-identified charts. Score it before the interview so the interview can probe the gaps.
5. Interview on judgement. Ask how the candidate handles unclear documentation, payer conflicts and pressure to upcode. Use the questions below.
6. Check references and plan the first audit. Ask former supervisors about audit scores and denial rates. Schedule a 30-, 60- and 90-day audit before the start date.

How do you test a coding specialist before you hire?

The most reliable way to test a coding specialist is a timed, practical test in which the candidate codes de-identified charts from your own specialty, scored against an answer key, with a pass mark close to the accuracy you expect on the job. Many coding teams set that bar at 95%.

A good coding test has four parts:

1. Knowledge check (20 to 30 minutes). Scenario questions on ICD-10-CM, CPT, HCPCS, modifiers and guidelines. A ready-made test saves your coding manager from writing and scoring one for every hire.
2. Chart coding (30 to 45 minutes). Five to ten short, de-identified notes from your specialty. Score each code, the sequencing and any missed codes.
3. Query writing (10 minutes). One unclear note. Ask the candidate to write the query they would send the physician. Good queries are short, specific and do not suggest an answer.
4. Compliance judgement (5 minutes). One scenario where a manager asks for a higher-paying code the note does not support.

Set the pass mark from your own audit policy. Many coding teams use 95% as the internal audit target, with extra training and a quick re-audit for anyone who falls short.

A candidate who scores in the low 80s on your test will start in remediation, so decide in advance whether you can support that.

Remote candidates need a fair, secure test. AAPC's 2026 report shows 64.8% of coders work fully remote and 15.4% hybrid, so most coding tests are taken from home.

Testlify includes 20+ proctoring checks, such as webcam snapshots, tab and copy-paste tracking and AI assistance detection, so remote scores hold up. See anti-cheating and proctoring for the full list.

A ready-made test stack for a coding specialist

• Medical coding test: Use this 40-question, 30-minute test on applied coding, documentation and audit readiness as the core screen for every coding hire.
• HIPAA test: Add this privacy and security check for anyone who handles patient records, especially remote coders.
• Medical billing specialist test: Add this claims and billing check when the role combines billing and coding.
• Attention to detail test: Add this check of how carefully a candidate works for entry-level or CPC-A hires.
• Your own chart coding exercise: Add de-identified charts from your specialty as a custom question with file upload or short answer to see how the candidate codes your real notes.

Testlify has 3,500+ ready-made tests, runs in 15+ languages and connects to 100+ ATS and HRIS systems, so scores land in the same place as the rest of the candidate record.

What interview questions should you ask a coding specialist?

The best interview questions for a coding specialist test judgment in real situations: unclear documentation, payer rules, denials and pressure to upcode. Technical recall is better checked in the coding test, so use the interview for how the candidate thinks.

Walk me through how you code an inpatient stay from admission to final DRG.

Listen for: principal diagnosis selection, secondary diagnoses, procedure codes, and checking the documentation before finalising.

How many charts do you code in a day, and how do you keep accuracy up at that pace?

Listen for: realistic numbers for their setting and a method, such as checklists or self-audits.

How did you prepare for the October ICD-10 update?

Listen for: reading the new code set and guidelines, specialty-specific changes, and updating any personal cheat sheets.

How do you work a denial that you think was caused by a coding error?

Listen for: checking the code against documentation, correcting and resubmitting, and telling the team so it does not repeat.

What was your accuracy score on your last audit, and what did the auditor flag? Listen for: a real number, specific errors and what the candidate changed afterwards.

A manager asks you to use a higher-level E/M code than the note supports. What do you do?

Listen for: a clear no, with the reason and an escalation path to compliance.

Tell me about a query you sent to a physician. What did you write?

Listen for: a short, non-leading question that gives clinical facts and asks the physician to clarify.

A note says "likely pneumonia" in an outpatient visit. How do you code it?

Listen for: in outpatient coding, uncertain diagnoses are not coded as confirmed; code the signs and symptoms instead.

What should a coding specialist job description include?

A coding specialist job description should name the setting, the code sets, the credential required, the systems used, the productivity and accuracy targets, and whether the role is remote. Specific postings attract qualified coders and save screening time.

How is AI changing the coding specialist role?

AI is moving the coding specialist from coding every chart by hand toward reviewing, correcting and auditing codes that software suggests. Computer-assisted and autonomous coding tools now handle many simple, high-volume encounters, while people handle complex cases, queries and compliance.

The BLS notes that AI tools that speed up medical coding may reduce demand for some of these workers. In practice, that changes what you should hire for:

• Validation over volume. The coder's value is spotting where the software got it wrong, so test with tricky charts, not easy ones.
• Query and documentation skills. AI cannot ask a physician what they meant. Clear queries become a bigger share of the job.
• Audit skills. Teams that use AI need people who can sample and audit its output, which is why CPMA-level skills pay more.
• Continuous change. New codes every October and April, plus new tools, reward people who learn fast.

Accuracy still carries a real cost. CMS reported a Medicare fee-for-service improper payment rate of 6.55% for fiscal year 2025, or $28.83 billion.

Not all of that comes from coding, but documentation and coding quality are part of keeping it down.

What mistakes should you avoid when hiring a coding specialist?

The costliest mistakes when hiring a coding specialist are hiring on the credential alone, testing with the wrong setting, ignoring remote test security, and skipping the first audit. Each one lets an inaccurate coder reach live claims.

• Trusting the credential alone. A CPC does not prove inpatient skill, and a CCS does not prove risk adjustment skill. Match the credential to the setting and test anyway.
• Testing on the wrong charts. A generic quiz will not show whether someone can code your orthopaedic or oncology notes. Add specialty charts.
• Unproctored remote tests. Most coders work remotely. Without proctoring, you cannot tell who did the test.
• Hiring for speed over accuracy. A fast coder at 85% accuracy costs more in denials and rework than a slower coder at 96%.
• No first-audit plan. Audit the first 30, 60 and 90 days so problems surface before they reach a payer audit.
• Ignoring culture and support. Remote coders still need a lead to ask, clear feedback and time for continuing education. Coders who feel unsupported leave, and replacing them takes months.

Key takeaway: Match the credential to the setting, prove accuracy with a practical, proctored test on your own charts, and plan the first audits before day one. That sequence finds coding specialists who keep claims clean.
