Seasonal Affective Disorder Is Now a Recognized Diagnosis in the CMS Tabular Index, Accessible to Prescribers Oct. 1, 2022

CMS Issues New Clarification on ICD-10 Coding for SAD

Bausch Health Companies Inc. (NYSETSX: BHC) ("Bausch Health") is continuing its commitment to improving lives with the announcement of modifications within the Tabular Index, specifically for the prevention and treatment of SAD from the Centers for Medicare & Medicaid Services (CMS). Now, all appropriate codes have been combined into a bundle for SAD which allows healthcare professionals to further clarify a diagnosis in an easy-to-understand index tab and send all diagnoses for SAD to one simple code: F33. This achievement helps further define SAD as a recognizable condition that may be diagnosed and appropriately treated.

More than 16 million people suffer from SAD in the United States alone. ^1,2 While the symptoms of SAD can be the same as those of Major Depressive Disorder (MDD), many people with SAD may experience these symptoms more frequently during the fall or winter months and may benefit from a treatment that does not need to be taken year-round. ^3-6

Prior to this important modification of the Tabular Index, it is believed that SAD has been underdiagnosed ⁷ and the ICD-10 is used to properly classify a disease and diagnosis. As of Oct. 1, 2022 , healthcare professionals will have access to a new instructional note for SAD at F33 in the Tabular Index and with that, sufferers may be more appropriately identified and prescribed an FDA-approved treatment for SAD.

INDICATION
APLENZIN® (bupropion hydrobromide extended-release tablets) is a prescription medicine used to treat adults with a certain type of depression called major depressive disorder, and for the prevention of autumn-winter seasonal depression (seasonal affective disorder).

IMPORTANT SAFETY INFORMATION

Call your healthcare provider right away if you or your family member has any of the   following symptoms, especially if they are new, worse, or worry you:

• thoughts about suicide or dying
• attempts to commit suicide
• new or worse depression
• new or worse anxiety
• feeling very agitated or restless
• panic attacks
• trouble sleeping (insomnia)
• new or worse irritability
• acting aggressive, being angry, or violent
• acting on dangerous impulses
• an extreme increase in activity and talking (mania)
• other unusual changes in behavior or mood

Although APLENZIN is not a treatment for quitting smoking, it contains the same active ingredient (bupropion) as ZYBAN, which is used to help patients quit smoking.

Some people have had serious side effects while taking bupropion to help them quit smoking, including:

New or worse mental health problems, such as changes in behavior or thinking, aggression, hostility, agitation, depression, or suicidal thoughts or actions. Some people had these symptoms when they began taking bupropion, and others developed them after several weeks of treatment, or after stopping bupropion. These symptoms happened more often in people who had a history of mental health problems before taking bupropion than in people without a history of mental health problems.

Stop taking APLENZIN and call your healthcare provider right away if you, your family, or caregiver notice any of these symptoms. Work with your healthcare provider to decide whether you should continue to take APLENZIN. In many people, these symptoms went away after stopping APLENZIN, but in some people, symptoms continued after stopping APLENZIN. It is important for you to follow-up with your healthcare provider until your symptoms go away.

Before taking APLENZIN, tell your healthcare provider if you have ever had depression or other mental health problems. You should also tell your healthcare provider about any symptoms you had during other times you tried to quit smoking, with or without bupropion.

• Seizures : There is a chance of having a seizure (convulsion, fit) with APLENZIN, especially in people with certain medical problems or who take certain medicines. Do not take any other medicines while you are taking APLENZIN unless your healthcare provider has said it is okay to take them. If you have a seizure while taking APLENZIN, stop taking the tablets and call your healthcare provider right away.
