F18.90

What This Code Means

This code describes a patient who uses inhalant substances (such as glue, paint thinner, or aerosols) but the specific pattern of use and any related complications are not documented. It is used when there is evidence of inhalant use but insufficient information to classify it as abuse or dependence.

Coding Tips

• •Use this code only when documentation indicates inhalant use without specifying abuse, dependence, or complications; if abuse or dependence is documented, use F18.1x or F18.2x codes instead
• •Verify that the documentation does not mention withdrawal symptoms, intoxication, or other substance-related disorders that would require a more specific code
