F11.91

What This Code Means

This code describes a patient with a history of opioid use disorder who is currently in remission, meaning they are not actively using opioids and their condition is controlled. The 'unspecified' designation indicates that the specific type of opioid use disorder (mild, moderate, or severe) is not documented.

Coding Tips

• •Use this code only when documentation clearly states the patient is in remission from opioid use; do not use if active use or relapse is occurring
• •If the severity level (mild, moderate, or severe) is documented, use the more specific codes F11.11, F11.21, or F11.91 with appropriate severity modifiers instead of the unspecified code
