What the code means
The discipline of Hepatology encompasses the structure, function, and diseases of the liver and biliary tract. The American Board of Internal Medicine considers Hepatology part of the subspecialty of gastroenterology. Physicians who identify themselves as Hepatologists usually, but not always, have been trained in gastrointestinal programs.

Where they are
Counted by practice location, not by mailing address or by licence state. A provider practising across a state line is counted where they practise.

Who registers under this code
309 of these are people and 54 are organisations, so 15% of the code is businesses rather than clinicians. Half of them had registered by 2008, and 29 registered in the last five years, 8% of the current population.
That is a slow-growing code, which usually means an established field replacing retirements rather than expanding.
Where the practices are
By practice-location city. City counts are noisier than state counts, because a large employer files one address for many providers.

Looking up a specific provider
These counts come from the monthly NPPES file. To check one provider, use their NPI: the lookup reads the live registry and shows whether the identifier is still active, which the monthly file cannot tell you about the last few weeks.
