Section 1: Record Completeness
Before worrying about whether data is accurate, check whether it's there at all. Missing fields are often a bigger problem than wrong fields because they're harder to catch in aggregate reporting.
1. What Percentage of Records Have a Verified Email Address?
Target: 70%+
Not just any email. A verified, deliverable email address. Generic addresses like info@, contact@, and frontdesk@ count, but should be flagged separately from individual addresses. If less than 50% of your records have any email at all, your outbound email channel is crippled before you start.
Run your emails through a verification service. The percentage that comes back as "valid" is your true coverage rate. Anything listed as "catch-all" should be treated as unverified because catch-all domains accept all incoming mail, so you can't confirm the specific address exists.
2. What Percentage of Records Have a Direct Phone Number?
Target: 40%+
By direct phone number, we mean a number that reaches a specific person, not the main office line. This includes direct extensions, direct dials, and cell phones. If your entire phone dataset is main office numbers, your reps are fighting through front desks on every single call.
40% might sound low, but direct phone coverage in healthcare is harder to achieve than in most B2B verticals. Providers are protective of their direct lines. Getting to 40% with verified numbers is a strong position.
3. Do Records Include a Named Decision-Maker?
Target: 80%+
Every practice record should include at least one named individual identified as a decision-maker or influencer for purchasing. This is the person your rep is trying to reach. "Dr. Smith" from the NPI registry isn't enough if Dr. Smith is an employed physician with no purchasing authority.
For practices where you don't have a named decision-maker, flag them for enrichment before including them in outreach. Sending email to info@ with "Dear Decision-Maker" is a waste of everyone's time.
4. Is Practice Size Data Available?
Target: 60%+
Do you know how many providers practice at each location? Provider count is the most commonly available size metric and it's essential for segmentation. A solo practice and a 20-provider group need completely different sales approaches, pricing conversations, and implementation plans.
If you don't have provider count data, you can approximate it by counting unique Type 1 NPIs associated with a practice address, but this is imprecise and misses non-NPI staff.
Bonus: Ownership Type Coverage
Target: 50%+
This is a stretch goal for most teams, but it's increasingly important. Do you know whether each practice is independently owned, hospital-affiliated, PE-backed, or part of a larger management group? Ownership type is the strongest predictor of buying behavior in healthcare B2B. Independent practices make fast, autonomous decisions. PE groups and hospital systems have centralized procurement. If you can't segment on ownership, you're sending the same pitch to buyers with fundamentally different processes.
Even partial coverage is valuable. If you can identify ownership type for your top 50% of target accounts, that's enough to create meaningful segmentation in your outreach. Start with the largest practices in your list. Ownership information is easier to find for bigger organizations because they tend to have more public-facing presence.
Section 3: Data Freshness
Even accurate data becomes inaccurate over time. These checks assess whether your data is current enough for outreach.
9. When Was Each Record Last Verified?
Target: Within the last 90 days
Not "when was the file last updated." When was each individual record last confirmed accurate? There's a critical difference. A vendor might "update" their file monthly but only re-verify a fraction of records each cycle.
If your data doesn't include per-record verification timestamps, you have no way to assess freshness at the record level. Ask your vendor for this. If they can't provide it, that tells you something about their verification process.
Provyx includes record-level verification timestamps on every deliverable. It's the only way to hold data quality accountable.
10. Are Deactivated NPIs Flagged and Excluded?
Target: 100% of deactivated NPIs identified
Cross-reference your provider list against the latest NPPES deactivation file. Deactivated NPIs represent providers who are no longer practicing, have died, or have had their billing privileges revoked. Reaching out to these records is not just wasteful; it can be embarrassing.
CMS publishes deactivation data monthly. This check should be part of your monthly maintenance routine.
11. Are Newly Registered Providers Being Added?
Target: Monthly additions from NPPES
New NPIs are issued every month as providers start practices, join new organizations, or enter the workforce. According to BLS projections, healthcare is one of the fastest-growing employment sectors. If you're not adding new providers to your database regularly, you're missing a growing portion of your addressable market.
This is especially important in specialties with high turnover or rapid growth. Urgent care, telemedicine, and mental health practices have exploded in the last three years.
12. Have Recent Practice Closures and Mergers Been Captured?
Target: Quarterly review of practice status
Practices close. Practices merge. Practices get acquired. If your database still shows "Smile Dental" as an independent practice when it was acquired by a DSO six months ago, your rep is going in with the wrong pitch to the wrong person.
Monitoring this requires more than NPI data. You need to watch for business registration changes, website updates, news mentions, and ownership filings. This is one of the hardest aspects of data maintenance to do manually, and one of the strongest arguments for using a commercial data provider that actively monitors these signals.
Scoring Your Audit
Go through each of the 15 checks and rate your data honestly:
- Meets target: 2 points
- Close but not there: 1 point
- Significantly below target: 0 points
Score interpretation:
- 25-30 points: Your data infrastructure is strong. Focus on maintaining quality and optimizing segmentation.
- 18-24 points: You have a solid foundation with meaningful gaps. Prioritize the lowest-scoring areas for immediate improvement.
- 10-17 points: Significant data quality issues are likely impacting your pipeline. Consider a complete data refresh before your next campaign.
- Below 10: Your data needs a complete overhaul. Stop outreach on the current list and invest in rebuilding from verified sources. Sending more volume on bad data will only make things worse.
Appendix: Tools for Running This Audit
You don't need expensive software to run most of these checks. Here are the tools that work:
For Email Verification
- ZeroBounce - Pay-per-verification model. Good for one-time audits. Provides deliverability scoring and catch-all detection.
- NeverBounce - Similar pricing model. Strong on accuracy. Integrates with most CRMs and email platforms.
- Kickbox - Developer-friendly API if you want to build verification into your data pipeline.
For Address Standardization
- SmartyStreets - USPS-certified address validation. Free tier for small volumes. Catches formatting errors and undeliverable addresses.
- Melissa Data - More complete suite that includes name parsing and phone validation alongside address standardization.
For Phone Validation
- Twilio Lookup API - Checks if a number is in service, identifies carrier, and classifies as mobile/landline/VoIP. Very affordable at per-lookup pricing.
- Numverify - Simpler phone validation. Good for batch checking number validity and line type.
For NPI Cross-Referencing
- NPPES downloadable files - Free from CMS. Updated monthly. The full file is large (7+ GB) but manageable with basic database tools.
- NPI Registry API - Free real-time lookups for individual records. Rate-limited but works well for spot checking.
Running this full audit manually using these tools takes about 2-4 hours for a list of 10,000 records. That investment of time will save your team weeks of wasted outreach on bad data. It's one of the highest-ROI activities a sales operations leader can do.
Frequently Asked Questions
How often should I audit my medical practice data?
Run a full audit quarterly and spot-check critical metrics (bounce rate, connect rate, wrong-contact rate) monthly. Data quality degrades 4-6% per month in healthcare, so waiting longer than a quarter between audits allows too much degradation to accumulate.
What's the most important data quality metric for healthcare sales?
Email bounce rate is the single most actionable metric because it's easy to measure, directly impacts campaign performance, and high bounce rates damage your sender reputation. If your bounce rate is above 5%, fix that before optimizing anything else.
How do I check if a provider is still at a listed practice?
Cross-reference against the practice's website (check the About or Our Team page), state licensing board records, and the latest NPI deactivation file from CMS. For large-scale verification, commercial data vendors like Provyx automate this process using multiple data signals.
What's a good data quality score for launching an outreach campaign?
Using the 15-point checklist in this guide, aim for a score of 18+ before launching any campaign. Below 18 means you have gaps that will meaningfully impact results. Below 10 means you should pause outreach and invest in data quality before spending more on outreach tools or rep time.
