About MDCodeLookup
Free healthcare tools built by healthcare professionals, for healthcare professionals and patients.
Our Mission
MDCodeLookup exists to make healthcare information accessible, understandable, and actionable for everyone — from medical billing specialists looking up NPI numbers, to patients trying to understand what their A1C level means.
We believe that critical health tools shouldn't be locked behind paywalls, cluttered with pop-ups, or buried in confusing interfaces. Every tool on this site is 100% free, works on any device, and requires no registration.
Who We Are
MDCodeLookup was founded by a team with combined experience in both healthcare and software development. We understand the daily challenges faced by medical coders, billers, clinicians, and patients — because we've worked in the same environment.
Healthcare Industry Experience
Real-world experience in healthcare operations, medical billing workflows, and clinical data systems. We know how POS codes, NPI numbers, and clinical assessments are actually used — not just what they mean on paper.
10+ Years Software Development
Over a decade of professional software engineering experience building web applications, data systems, and interactive tools. Every calculator and lookup tool is purpose-built, not a generic template.
Evidence-Based Approach
Every calculator follows published clinical guidelines from organizations like the AHA, ADA, WHO, and NIH. We cite our sources, follow validated scoring systems, and clearly distinguish tools from medical advice.
What We Offer
Health Calculators
From BMI and A1C to PHQ-9 depression screening and ASCVD risk — clinically validated calculators with color-coded results, educational content, and evidence-based interpretations.
Health Articles
In-depth guides explaining what your health scores mean, when to see a doctor, and what steps to take next. Written in plain English, backed by medical literature.
Professional Lookup Tools
NPI Number Lookup searching the live CMS NPPES database, and Place of Service Codes reference with instant search — tools built for medical billing professionals.
How We Ensure Accuracy
Health information carries responsibility. Here's how we maintain the accuracy and reliability of every tool on this site:
Clinical Guidelines First
Every calculator is built on published, peer-reviewed clinical guidelines. We use scoring systems from the American Heart Association (AHA), American Diabetes Association (ADA), World Health Organization (WHO), National Institutes of Health (NIH), and other recognized bodies.
Validated Scoring Systems
Mental health screeners like PHQ-9, GAD-7, DASS-21, and AUDIT use the exact validated scoring criteria from their original research publications. We don't modify or "simplify" clinical instruments.
Official Data Sources
Our NPI Lookup pulls data in real-time from the CMS NPPES API. Place of Service codes are sourced from the official CMS POS Code Set database. We use authoritative government sources, not third-party copies.
Regular Updates
Healthcare guidelines change. We monitor updates to clinical scoring systems, CMS code sets, and medical reference data. When guidelines are updated, our tools are updated to match.
Clear Disclaimers
Every tool includes a clear disclaimer that results are for informational purposes and should not replace professional medical advice. We help users understand their numbers — we don't diagnose or prescribe.
Editorial Policy
Source Citations
All health content references official clinical guidelines, published studies, or government health databases. Sources are cited within calculator pages and blog articles.
No Medical Advice
Our tools help you understand health metrics — they don't provide diagnoses or treatment recommendations. We always encourage consulting a qualified healthcare provider.
No Sponsored Content
Our health content and calculator results are never influenced by advertisers or sponsors. Tools give you accurate results regardless of any advertising displayed on the site.
Corrections Welcome
If you find an error or outdated information in any of our tools, please contact us. We take accuracy seriously and will investigate and correct any verified issues promptly.
