Why coding decides what you are paid
Every payment starts with codes. CPT and HCPCS Level II codes describe what was done, ICD-10-CM codes describe why, and modifiers explain circumstances the base code cannot. Payers decide coverage, bundling and payment from those codes alone; they rarely read the note unless they audit it. That makes coding the point where documentation either becomes revenue or becomes risk.
Two problems show up again and again. Under-coding — choosing a lower level or missing a separately billable service — loses revenue the practice has already earned. Over-coding — a level or modifier the documentation does not support — is paid at first and becomes a refund demand, or worse, after an audit. Accurate coding is not about maximizing codes; it is about the codes matching the record.
What our coders review on every encounter
- Evaluation and management (E/M) level chosen from medical decision-making or total time, as the 2021 and 2023 AMA guideline changes require.
- Procedure codes including add-on codes, units and bilateral or multiple-procedure reporting.
- Diagnosis specificity so ICD-10-CM codes support medical necessity and, for risk-adjusted plans, reflect documented chronic conditions.
- Modifiers such as 25, 59 and the X{EPSU} subset, 26 and TC, used only when the documentation supports them.
- Edits and policies: NCCI procedure-to-procedure edits, medically unlikely edits (MUEs) and the coverage determinations that apply to your Medicare contractor.
Coding audits
An audit samples your claims and compares the codes with the documentation. We report accuracy by provider and by code family, explain each finding with the guideline behind it, and separate two kinds of result: revenue you are missing and risk you are carrying. Where an error has already been paid, we explain the options for correcting it rather than leaving you to discover it in a payer audit.
Documentation feedback that providers will read
Coding queries work when they are specific. Instead of “please document more”, a query names the encounter, the missing element (for example, the time spent, the independent interpretation, or the laterality) and the code it affects. Patterns are summarized monthly so providers see the two or three habits that matter most for their specialty. See how this applies in cardiology, orthopedics and gastroenterology.
Coding and billing together
Coding feeds billing directly: when coding and claim follow-up sit with the same team, denials caused by codes come back to the coder who can fix the pattern. Many practices combine this service with medical billing; others keep billing in house and use us for coding and audits only.
