Medical coding is a detail-intensive profession where accuracy directly impacts patient care, billing integrity, and compliance. Yet coders are often expected to make complex clinical judgments quickly and without the right reference tools at hand.
The Dx Drop was created to close that gap. We believe every coder, whether in their first week studying for the CPC or their tenth year in the ED, deserves fast, reliable access to the clinical information that supports better coding decisions.
Signs and Symptoms Tool: Look up any ICD-10-CM diagnosis by condition name, common abbreviation (RSV, DKA, COPD), or ICD-10 code. See the associated signs and symptoms instantly, side by side for up to three conditions at once.
Coding Reference Guides: Downloadable PDF and digital reference materials covering high-yield ICD-10-CM categories, available through our Etsy shop. Designed for quick reference during coding sessions and active CPC exam study.
More tools and resources are in development. The Dx Drop is continuously growing.
The Dx Drop is designed for:
Medical coding students preparing for the CPC, CCS, or COC exam
New coders building foundational knowledge of ICD-10-CM
Experienced ED and outpatient coders who want a faster reference workflow
Healthcare educators and instructors looking for supplemental resources
The Dx Drop is an educational and reference resource. All content is intended to support, not replace, official coding guidelines, physician documentation, and professional coding judgment. Codes and descriptions are sourced from the CMS 2026 ICD-10-CM tables (public domain). Signs and symptoms are compiled for educational purposes from established clinical references.
