Medical Coding Services That Are Precise Enough to Survive Any Audit.
Professional ICD-10, CPT & HCPCS coding services for healthcare providers nationwide
One wrong code doesn’t just cause a denial — it can trigger a payer audit, require repayment of previously collected claims, and create a compliance liability that takes months to resolve. Theiatrics’ AAPC-certified medical coding team assigns the most accurate, most defensible code for every encounter — maximizing your reimbursement while protecting your practice.

What Are Medical Coding Services
— and Why Precision Matters More Than Speed
Medical coding services translate clinical documentation — physician notes, operative reports, lab results, and discharge summaries — into standardized ICD-10-CM diagnosis codes, CPT procedure codes, and HCPCS Level II codes used by insurance payers to determine reimbursement. Every claim submitted to an insurer is built on a foundation of these codes.
The codes assigned to a patient encounter determine exactly how much your practice gets paid — and whether the claim gets paid at all. A code that is too vague results in a lower reimbursement than you've earned. A code that doesn't match the documented diagnosis triggers an automatic denial. A code that consistently over-represents the severity of encounters flags your practice for a payer audit.
Accuracy isn't optional in medical coding — it's the difference between collecting what you've earned and spending months in a compliance review. Our AAPC-certified coders bring specialty-specific expertise to every encounter, assigning the most accurate, most specific, and most defensible code supported by the clinical documentation.
Unlike generalist coders who rotate across specialties, our teams are permanently assigned to the specialty they know. The coder reviewing your gastroenterology encounters has coded GI procedures — and nothing else — for years. That depth of expertise is what produces a 99.1% coding accuracy rate and coding-related denial rates under 1.2%.

Most providers think about coding errors in terms of individual claim denials. The real risk is much larger. Systematic coding inaccuracies — whether from overcoding, undercoding, or code-diagnosis mismatches — can trigger payer audits, OIG investigations, and repayment demands that cover years of previously collected claims.
At the same time, consistent undercoding quietly drains revenue that you've legitimately earned — often without your knowledge or your billing team's. Research shows the average practice undercodes by 7–12% of its collectible revenue, simply because their coders assign conservative codes rather than the most specific and accurate ones the documentation supports.
Check My Coding Accuracy — Free →When a coder assigns a lower-level E/M code than the documentation supports — or misses a billable procedure — you simply collect less than you're owed. There's no denial. No report. The revenue just never materializes. Most practices that switch to professional medical coding services discover immediate, measurable revenue improvement from this one fix alone.
Insurance payers use advanced data analytics to compare your coding patterns against specialty peers. If your E/M level distribution skews significantly higher than average, or if certain high-value codes appear at unusual frequency, your practice gets flagged — triggering a pre-payment or post-payment audit that can result in repayment demands covering years of claims.
Diagnosis-to-procedure mismatches, non-covered diagnosis codes, invalid code combinations under NCCI edits, and missing modifier information are all coding-level denials. They're entirely preventable with the right expertise — and our coding-related denial rate of under 1.2% proves that precise, specialty-specific coding eliminates most of this loss before a claim is ever submitted.
Specialty-Specific Medical Coding — Not One-Size-Fits-All
Gastroenterology coding requires deep knowledge of endoscopy bundling rules and polyp-removal add-on codes. Anesthesia coding uses a completely different time-unit model. Cardiology coding involves dozens of procedure-specific documentation requirements. A coder who handles all three is almost certainly doing all three poorly.
Every specialty we serve has its own dedicated coding team. They code your specialty exclusively — which means they know your procedures, your payer quirks, and your most common coding challenges better than any generalist pool ever could.

In-house coders are often asked to handle multiple administrative functions in addition to coding. They may not specialize in your specific procedures.
Professional medical coding services bring dedicated specialists with ongoing credentialing, specialty-specific training, and access to the most current payer policies.

We had no idea how much we were leaving on the table from conservative E/M coding. Theatrics reviewed our last six months of encounters and found we had undercoded on nearly 18% of them. Within the first quarter of switching, our collections were measurably higher — and we hadn’t changed a single clinical process.

Gastroenterology coding is genuinely complex. Add-on codes, bundling rules, modifier requirements for multiple polyp removals — our previous coder was getting most of it wrong because she coded everything from hospitals to dermatology. Theatrics’ GI-specific team got it right from day one. Our denial rate dropped from over 14% to just over 2% within three months.
Gastroenterology Practice – Houston, TX
I was worried about a payer audit because our billing had been inconsistent for years. Theatrics did a full coding audit before we started, corrected our historical patterns, and set up a compliant coding framework going forward. A year later, we’ve had zero audit issues and our reimbursements are the most consistent they’ve ever been.
