Nicotine dependence, chewing tobacco, w oth disorders

This code signifies a patient's physiological or psychological dependence on chewing tobacco, accompanied by additional health problems directly attributable to nicotine use. These "other nicotine-induced disorders" can encompass a range of conditions such as nicotine withdrawal, nicotine-induced anxiety disorder, or nicotine-induced sleep disorder. It indicates a more complex presentation than simple nicotine dependence.

Apply this code when documentation clearly states a diagnosis of nicotine dependence specifically from chewing tobacco, and also identifies a co-occurring nicotine-induced mental or behavioral disorder. This requires explicit physician documentation linking the chewing tobacco use to the dependence and the additional nicotine-related disorder.

• Ensure the documentation specifies "chewing tobacco" as the source of nicotine dependence, not other forms.
• Verify that a specific "nicotine-induced disorder" is documented and not just general symptoms.
• Sequence this code as a secondary diagnosis when the nicotine-induced disorder is the primary reason for the encounter.
