What does code 300.00 mean for medical billing?

The ICD-10 code 300.00 stands for moderate persistent depressive disorder (MDD).

It is a mental health condition characterized by a depressed mood most of the time for a duration of at least two years accompanied by additional symptoms such as:

loss of energy, feelings of inadequacy, decreased concentration, sleep and appetite disturbances, and avoidance of social activities.

In medical billing, code 300.00 is used to indicate this specific diagnosis when submitting claims for reimbursement from insurance companies or government healthcare programs.
