What We Code

Certified coding across specialties, code sets, and claim types

Coding errors are a leading cause of denials, underpayments, and compliance exposure. A single miscoded claim can trigger an audit, delay reimbursement, or leave revenue permanently uncollected. Our certified coders ensure every chart is coded accurately, completely, and compliantly.

CPT & Procedure Coding

We assign the correct CPT codes for every service, procedure, and visit documented in your charts — eliminating the most common source of denials.

ICD-10 Diagnosis Coding

We assign specific, well-supported ICD-10-CM codes that reflect the full complexity and severity of your patients’ conditions — supporting accurate reimbursement, risk adjustment, and payer compliance.

Evaluation & Management (E/M) Coding

E/M is one of the highest-risk areas in coding — for both undercoding and overcoding. Our coders apply current AMA E/M guidelines to assign the correct level for every visit.

Specialty-Specific Coding

Coders are matched to your specialty, bringing deep knowledge of the coding patterns, bundling rules, and documentation requirements specific to your practice type.

HCC & Risk Adjustment Coding

For Medicare Advantage and value-based contracts, we identify and capture all documented HCC-eligible diagnoses, so your risk scores and revenue reflect your patients’ true complexity.

Most Requested

Coding Audits & Compliance Review

Prospective and retrospective audits identify patterns of undercoding, overcoding, or documentation gaps before they become a payer or compliance issue — with actionable recommendations.
