F20.0 is a billable ICD code used to specify a diagnosis of paranoid schizophrenia. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code F200 is used to code Paranoia

Paranoia is a thought process believed to be heavily influenced by anxiety or fear, often to the point of irrationality and delusion. Paranoid thinking typically includes persecutory, or beliefs of conspiracy concerning a perceived threat towards oneself (e.g. "Everyone is out to get me"). Paranoia is distinct from phobias, which also involve irrational fear, but usually no blame. Making false accusations and the general distrust of others also frequently accompany paranoia. For example, an incident most people would view as an accident or coincidence, a paranoid person might believe was intentional.
