Medical Coding

The Challenge

Medical coding sits at the intersection of clinical documentation and financial reimbursement — and it is one of the most common sources of revenue loss in healthcare. Undercoding leaves money on the table. Overcoding triggers audits, recoupments, and compliance violations. Inaccurate code selection leads to claim denials that cost time and resources to resolve.

The coding landscape grows more complex every year. Annual ICD-10-CM updates, CPT code revisions, evolving modifier requirements, and payer-specific coding edits demand continuous education and vigilance. For practices without dedicated certified coders, maintaining accuracy and compliance across thousands of encounters is nearly impossible.

The financial impact is substantial. Studies consistently show that coding errors contribute to 30-40% of all claim denials, and the average practice loses 5-10% of potential revenue to charge capture gaps and incorrect code assignment.

Our Approach

DeltaRCM's coding team consists of certified professionals — CPC, CCS, and specialty-credentialed coders — who combine clinical knowledge with deep payer expertise to assign the most accurate and reimbursable codes for every encounter.

Chart review and code assignment: Our coders review clinical documentation to select the appropriate CPT, ICD-10-CM/PCS, and HCPCS Level II codes. We evaluate every encounter for proper E/M leveling, procedure coding, modifier usage, and diagnosis specificity to ensure maximum reimbursement within compliance boundaries.

Charge capture optimization: We identify commonly missed charges — ancillary services, add-on codes, bilateral procedures, and qualifying modifiers — that your practice may be leaving off claims. Our audits routinely uncover 3-8% in additional revenue from overlooked billable services.

Compliance and audit readiness: Every code we assign is defensible against payer and government audits. We follow CMS guidelines, AMA CPT conventions, and payer-specific Local Coverage Determinations (LCDs) and National Coverage Determinations (NCDs). Our internal quality assurance program includes random audits and inter-rater reliability checks.

Provider education: We provide ongoing feedback to your providers on documentation gaps and coding opportunities, helping them capture the clinical detail needed to support higher-level codes without compliance risk.
