Medical Coding Services

Medical coding services

Medical coding services turn the clinician's documentation into the CPT, HCPCS and ICD-10-CM codes that a payer will accept and pay correctly.

See where claims are getting stuck. No patient data needed.

Our coders read the note, assign the codes and modifiers the documentation supports, query the clinician when it does not, and feed back the patterns that cause denials and underpayments.

This is part of getting the claim out clean. Buy it on its own or pair it with our other billing services, stage by stage.

What medical coding covers

Evaluation and management levels assigned from the medical decision making and time rules in force, with the elements documented in the note, not inferred from the diagnosis

Procedure coding for office, surgical, therapy and diagnostic services, with units and modifiers (25, 59 and the X modifiers, 95 for telehealth, KX, GA and GZ) applied where the documentation supports them

ICD-10-CM coding to the highest specificity the note allows, with laterality, episode of care and sequencing rules applied

HCPCS Level II for supplies, drugs (with J-code units and NDC where required), DME and transport

Clinician queries written in a compliant, non-leading format when documentation does not support a code

NCCI edits and MUE limits checked before the claim is built, so bundling denials are prevented rather than appealed

Payer-specific coding policies tracked where they differ from CMS, especially Medicaid programs and some commercial plans

Feedback to each clinician, on a schedule you choose, on the codes being downcoded, the documentation gaps and the denial patterns tied to coding

What goes wrong when medical coding is skipped

The 99214 that reads like a 99213

The visit involved two chronic conditions and a prescription decision, which is moderate decision making. The note lists the conditions but never states their status or the decision. A coder who reads the note has to assign 99213; an auditor reading it later will too. The difference, visit after visit, is real money, and the fix is a sentence in the note.

Modifier 25 on everything

A practice appends modifier 25 to every E/M billed with a procedure. Payers notice. Claims are pended for records, some are denied, and the practice is now on a review list. Modifier 25 belongs on the visits where a separately identifiable E/M is documented, and nowhere else.

The unspecified diagnosis

Unspecified codes are accepted less and less. Payers deny for lack of specificity or medical necessity; the note usually had the detail, and nobody coded it.

How we run medical coding

Documentation review

We read a sample of each clinician's notes against the codes billed and tell you where the documentation and the coding disagree, in both directions.

Coding

Encounters are coded inside your system from the signed note, and held for query where the note is unclear.

Queries

Short, specific questions to the clinician that can be answered in the EHR, with the claim held until the answer is in the record.

Edits before submission

NCCI, MUE, coverage determinations and payer policy checks run on the coded encounter before charge entry.

Feedback

A summary per clinician: what changed, what is being denied, and the two or three documentation habits that would fix most of it.

What you receive every week

Coded encounters in your system

Every encounter coded and ready for charge entry, with a query flag where the note needs the clinician.

Query log

Open and answered queries, so you can see which clinicians are being asked what, and how long answers take.

Coding review by clinician

Per clinician: level distribution, modifier use, denial patterns tied to coding, and specific documentation fixes.

Worked example: the therapy units

A hypothetical physical therapy clinic documents thirty-eight minutes of timed services: twenty-three minutes of therapeutic exercise (97110) and fifteen minutes of manual therapy (97140). Under Medicare's timed-code rules that is three total units, not four. The coder assigns two units of 97110 and one of 97140, with the X modifier this payer requires on 97140 when billed alongside 97110, and the documentation to support it. Billing four units would have been denied under the MUE and, repeated, would invite an audit.

Questions about medical coding

Do your coders hold certifications?

Credentials for the people who work your account are stated exactly as held, and we tell you who will code for you before you sign. We do not make general claims about certification.

Can the clinician keep coding and you check it?

Yes. Many practices prefer clinician-coded encounters with a coder review before submission. We catch the errors, raise the queries, and you keep control of the level.

What is a coding query?

A written question to the clinician when the note does not support a code. It has to be non-leading: we describe what is missing and ask, we do not suggest the answer. The claim waits until the record is updated.

Do you code from the EHR or from paper?

From the EHR, inside your system. We do not take exports of clinical notes or work from scanned superbills unless that is how your practice already documents.

How do you keep up with code changes?

Annual CPT and HCPCS updates, the ICD-10-CM updates, quarterly NCCI edits and payer policy bulletins for your payers are reviewed as they land, and the changes that affect your specialty are put in writing for your clinicians.

Will coding reviews slow down billing?

No. An encounter moves to charge entry as soon as it is coded. The only delay is a query, and the alternative to a query is a denial.

Should we hire a coder or outsource coding?

Hire if you have the volume to keep a certified coder busy all week and someone to check their work. Outsource if coding is one of several jobs for one person, if your clinician codes and nobody reviews it, or if a coder leaving would stop claims. The coding reviewer works remotely from your signed notes, so there is nothing to scan or mail. If you are deciding between hiring a biller and a coder, hiring a medical biller sets out how the two roles differ.

How does a remote coder see our notes?

As a user in your EHR, with a role that shows the signed note and the superbill and nothing more than the work needs. Queries go back through the EHR in compliant, non-leading form. No notes are exported, printed or emailed. Remote medical billing explains the access model in full.
