Coding is where clean claims start or where denials get written in. Our coders work specialty by specialty, applying ICD-10-CM, CPT, and HCPCS rules the way each payer actually enforces them, not a generic template.
Other billing scopes
Diagnosis codes selected to the correct specificity — a vague or mismatched diagnosis code is one of the most common reasons a clean-looking claim still gets denied.
Procedure and E/M codes matched to documented time and complexity, including psychotherapy add-on codes for behavioral health visits.
Supplies, injectables, and non-physician services coded correctly so they aren't bundled, dropped, or denied as not separately reimbursable.
This is where our coding knowledge runs deepest — correct E/M plus psychotherapy add-on codes, applied based on documented time, for PMHNP-BC and psychiatrist visits.
Brief psychotherapy add-on. Example: 99214 + 90833.
Mid-length psychotherapy add-on. Example: 99205 + 90836.
Extended psychotherapy add-on. Example: 99215 + 90838.
90792 — Psychiatric diagnostic evaluation with medical services (new patient intake)
99417 — Prolonged services add-on when total visit time exceeds the E/M code's typical time
90847 — Family therapy with patient present
90839–90840 — Crisis psychotherapy codes for high-acuity sessions
The same coding mistake tends to repeat across every claim until it's caught — one error can quietly touch months of billing.
Coding conservatively to avoid audits often means billing for less than what was actually documented and performed.
Codes that don't match documentation are exactly what payer audits are built to catch — accuracy protects the practice both ways.
We'll review a sample of recent claims against your documentation, flag undercoding, overcoding, and modifier errors, and show you exactly what a correction would have recovered — at no cost.
Coding is billed as part of our full Medical Billing service — 2.5% to 5% of collections, no flat monthly fee.

Yes. A coding audit reviews a sample of recent claims against your documentation to identify undercoding, overcoding, and modifier errors before they turn into denials or audit exposure.
Yes — it's our deepest area of expertise. Psychotherapy add-on codes, E/M level selection by session time, and crisis or intensive-program codes are applied by documented time, not estimated.
No. Coding is one part of the full Medical Billing service — you don't pay separately for coding, claims, and follow-up.
Coding feeds directly into claim submission — see how the two work together.
