HealthGraph: Predictive Models

• What is the probability claim X will be denied?

• A new customer just searched for “family practice”; recommend the best provider within 10 miles.

• Given a CPT code, what is the expected reimbursement rate from insurance company A in zip code 37601?

Shout-outs:Jython projectRexpro Python

Advantages:Initial exploratory value via quickly

standing up graph traversals via python syntax

Better team integration across API development/data science

1. Transition to Titan 1.0 and Tinkerpop 3.0

2. Keep the communication open between the data team and the API team to continue building out this integration

3. Deploy Python implementations of fundamental graph algorithms:

BFS, DFS, Dijkstra, … etc
