Medical Biller and Coder Resume Keywords: Billing vs Coding

One title, two different jobs

When I recruited for billing and coding openings, my first question to every hiring manager was the same: how many hours a day will this person spend on the phone with insurance companies? For postings with identical titles, the answers went from "almost none" to "most of the shift."

That answer decides your keywords. Coding work starts with provider documentation: reading the visit note or operative report, assigning codes, and asking the provider when something is missing. Billing work starts with the claim: sending it, checking what the payer paid, and following up on what it did not pay. Small practices often give both jobs to one person. Larger health systems often split them into separate teams with separate titles, such as "PB Coder" and "A/R Specialist."

The verbs in a posting tell you which job it is, even when the title does not.

Mark these verbs before you change anything on your resume. Our guide on how to find job description keywords covers the full method for pulling terms out of a posting.

Billing keywords follow the life of a claim

Billing is several jobs, too. One recent billing and A/R posting on the AAPC job board was direct about it: applicants whose background was mainly charge entry, payment posting or front-end work, with little denial or follow-up experience, were unlikely to fit. Medical billing resume keywords work best when they show which stages of the claim you actually handled.

Before the claim

• Eligibility and benefits verification
• Prior authorization
• Patient registration
• Coordination of benefits (COB)
• Copays and deductibles
• Good faith estimates for self-pay patients

Building and sending the claim

• Charge entry
• Charge capture and reconciliation
• CMS-1500 (837P) for professional claims
• UB-04 (837I) for facility claims
• Claim scrubbing
• Clearinghouse rejections
• Electronic claim submission

After the payer responds

• ERA (835) and EOB review
• Payment posting
• Contractual adjustments
• Underpayment review
• Denial management
• Appeals and reconsiderations
• Corrected claims
• Timely filing
• A/R follow-up
• Aging reports
• Credit balances and refunds
• Patient statements

Two details make medical biller resume skills much easier to judge. First, name the payers you billed. Each one follows different rules, and postings that mention workers' comp or no-fault often want someone who has billed them before.

• Medicare
• Medicaid
• Medicare Advantage
• Commercial plans
• Workers' compensation
• Auto or no-fault

Second, name the denial types you worked:

• Medical necessity
• Bundling (NCCI)
• Missing authorization
• Timely filing
• Coordination of benefits (COB)
• Duplicate claims

"Resolved medical necessity and timely filing denials for Medicare Advantage plans" gives a billing lead much more to work with than "handled denials."

Use "rejection" and "denial" correctly. A rejection is a claim stopped before processing, usually because of a data or format error caught by the clearinghouse or payer. A denial is a claim the payer processed and refused to pay. A billing lead I recruited for asked every candidate to explain that difference in the first five minutes of the phone screen.

If you supervise a billing team or the wider revenue cycle, our guide to healthcare administration resume keywords covers the management side.

Coding keywords: write the code sets exactly

Coding postings list code sets almost word for word, for example "assign ICD-10-CM, CPT and HCPCS codes from provider documentation." Use the same names on your resume, and include only the code sets you actually use.

• ICD-10-CM for diagnoses, used in every setting.
• ICD-10-PCS for inpatient hospital procedures only. It belongs on an inpatient resume next to MS-DRG. On a physician-office resume, it makes a reader wonder where you used it.
• CPT for procedures and services on professional and outpatient claims.
• HCPCS Level II for supplies, drugs (J-codes) and some services, common in oncology, infusion and DME.
• Modifiers, named individually: 25, 59 and the X modifiers (XE, XS, XP, XU), 26 and TC, RT and LT.

Guidelines and references are useful medical coding resume keywords too:

• E/M guidelines (medical decision making or time)
• NCCI edits and MUEs
• LCDs and NCDs for medical necessity
• AHA Coding Clinic
• CPT Assistant

Naming the references you check shows that you follow official guidance when a case is unclear. If you send provider queries or work with clinical documentation improvement (CDI) staff, add that as well.

A common shortcut is copying the full list from a course outline. ICD-10-PCS, DRGs, APCs and risk adjustment all on one resume, from someone with six months of clinic coding, is one of the resume keyword mistakes a coding manager can spot quickly.

Medical coder resume keywords start with setting and specialty

Keyword vocabulary changes between industries. In coding, it also changes between settings inside the same hospital. Coding managers usually hire for a setting and a specialty, and "multi-specialty" on its own does not tell them much. Name the specialties.

The coder resumes I could place fastest put the specialty in the job title line, for example "Professional Fee Coder (Orthopedics)," so nobody had to read three bullets to find it. Keep your real title, and add the specialty in parentheses if your employer's title did not include it.

What each credential tells a hiring team

Each credential points to a different kind of work. Recruiters often search their applicant tracking system by the abbreviation, so write it exactly the way the issuing body does.

Put your credentials after your name ("Jordan Ellis, CPC, CRC") and again in a Certifications section with the issuing body and the year. Write the full name once next to the abbreviation, for example Certified Professional Coder (CPC), because postings use both forms. Specialty credentials such as CEMC for E/M coding are worth listing when the posting is in that specialty.

Name every layer of software you used

"Experience with medical billing software" tells a reader very little. Coding and billing work runs on several systems at once, and each one is a separate keyword. Software is also one of the easiest medical coder resume skills to make specific.

• EHR: Epic, Oracle Health (Cerner), athenahealth, eClinicalWorks, NextGen, Meditech. In Epic, name the module and the work you did in it. One health system posting for a professional billing coder asked for experience resolving coding edits in Epic's charge review, claim edit and follow-up work queues. "Resolved coding edits in Epic Resolute PB work queues" matches that language closely.
• Encoder: Optum EncoderPro, 360 Encompass (sold for years as 3M 360 Encompass, now under Solventum), TruCode, Find-A-Code. Use the name the posting uses. If the posting says 3M and your login screen said Solventum, "3M/Solventum 360 Encompass" covers both.
• Computer-assisted coding (CAC): if your employer used it, say what you did with it, for example validating or correcting suggested codes.
• Clearinghouses and payer portals: Waystar, Availity, TriZetto, Office Ally. Some billing postings ask for experience with more than one clearinghouse, so list each one you used.
• Practice management: Tebra (formerly Kareo), AdvancedMD, or the PM side of your EHR.
• Excel: billing postings that list it usually mean A/R reports and reconciliation. "Built weekly aging reports in Excel with pivot tables" says more than "Microsoft Office."

Coding supervisors I recruited for were often vague about soft skills and very exact about the encoder. "She'll be in EncoderPro all day" is a note I wrote down more than once.

Numbers that coding and billing teams already track

Coding and billing departments measure their work closely, so you may already know your numbers. Use the ones your employer actually reported.

For coding:

• Accuracy on internal or external audits
• Productivity (charts or encounters per hour or day)
• DNFB for inpatient coders
• Provider query volume

For billing:

• Clean claim rate
• First-pass resolution rate
• Denial rate
• Days in A/R
• Percentage of A/R over 90 days
• Collection rate
• Number or dollar value of claims you worked

A productivity number means little without the chart type. A daily count that is normal for radiology reads would be unrealistic for inpatient surgical cases. I started asking for the chart type every time a coder gave me a productivity number, because the coding managers I worked with always asked it next.

Two examples:

Maintained 96% to 98% accuracy on quarterly internal audits while coding emergency department professional fee encounters in Epic and EncoderPro.

Reduced A/R over 90 days from 22% to 14% in two quarters for a four-provider orthopedic group by working aging reports by payer and appealing authorization and timely filing denials.

If you never saw a report, describe the volume instead: "Worked a daily queue of 50 to 70 commercial and Medicare Advantage claims." Leave out any percentage you cannot explain in an interview.

CPC-A, Practicode, and the experience question

Entry-level coding postings often accept a CPC-A but still ask for some coding experience, sometimes six months, sometimes a year or more. AAPC removes the apprentice designation after two years of experience, after one year combined with its Practicode program or an 80-hour coding course, or after completing both Practicode and the course. Until then, your resume needs to be honest about the "A" and specific about everything else.

• Write CPC-A exactly as issued. Once the A is removed, list only CPC with the date. Listing both can make a quick reader think you are still an apprentice.
• Put Practicode under Education or Training, not Work Experience. Describe what it covered: redacted patient records, operative reports, E/M visits and encoder use. Coding managers are split on how much it counts, and for roles that require experience, some will not treat it as experience.

Also use the keywords from healthcare jobs you already had. Coding teams sometimes hire from their own billing and front office staff, so these roles are a realistic route in:

• Front desk: eligibility verification, prior authorization, patient registration
• Medical records: release of information, HIPAA
• Charge entry and payment posting: billing work in their own right

If you are moving from a clinical support role, our guide to medical assistant resume keywords covers the administrative terms that overlap.

One job, written for two postings

The same experience can fit a coding posting or a billing posting, depending on what you put first. This is where medical biller and coder resume keywords do the most work. Here is one office coordinator at a two-provider dermatology practice who handled a bit of everything.

For a coding-focused posting:

• Assigned CPT, ICD-10-CM and HCPCS Level II codes for E/M visits, biopsies, excisions and Mohs surgery (17311 to 17315).
• Applied modifiers 25 and 59 using NCCI edits, cutting modifier-related denials by about half over 12 months.
• Queried providers when notes were missing the lesion size, site or margins needed for excision coding.

For a billing-focused posting:

• Submitted CMS-1500 claims through Waystar and cleared clearinghouse rejections within one business day.
• Worked aging reports by payer and appealed medical necessity and bundling denials with commercial and Medicare Advantage plans.
• Posted ERA and paper EOB payments and reconciled daily deposits.

Nothing in either version is invented. The difference is order and emphasis, and the top third of the resume (title line, summary and first bullets) should change with it. Our guide to matching your resume to a job description walks through that routine. To see which terms from a specific posting are still missing, paste both into the Resume Keyword Scanner. The AI Resume Optimizer can suggest rewrites that shift emphasis without changing facts, and the ATS Resume Checker confirms that both versions still read cleanly.

Common questions

Should I write "medical billing and coding" or list billing and coding separately?

Both. Use the combined phrase in your title line or summary if your target postings use it. Then group your medical billing and coding resume skills into separate billing and coding lists, so a coding manager and a billing lead can each find their part quickly.

Is it worth listing specific CPT codes?

Code ranges for your main services can help, such as office E/M (99202 to 99215) or Mohs surgery (17311 to 17315). A long list of single codes takes space and says less than your specialty and setting.

Should ICD-9 still be on my resume?

US claims moved to ICD-10 in October 2015. Unless a posting mentions old records, leave ICD-9 off.

Should I mention remote work?

If a job was remote, add "Remote" to its location line. Remote coding and billing postings sometimes ask for experience working independently against productivity targets, and that line answers the question early.

Is computer-assisted coding or AI experience worth listing?

Yes, if you used it in a real job. Name the system and your role, for example "Validated CAC-suggested codes in 360 Encompass for outpatient facility charts." A general claim about "AI tools" without a system name gives a reader little to check.
