Underdosing of other psychostimulants, subsequent encounter

This code indicates that a patient is experiencing adverse effects or complications due to taking less than the prescribed or recommended dose of a psychostimulant medication, other than methylphenidate or amphetamines. This underdosing is occurring during a follow-up visit for the initial problem.

Use this code when a patient presents for ongoing management of a condition, and their current symptoms or issues are directly related to not taking enough of their prescribed psychostimulant (e.g., modafinil, armodafinil) during the subsequent encounter. This could include situations where the patient is intentionally or unintentionally taking a lower dose than prescribed, leading to suboptimal therapeutic effects or worsening of their underlying condition.

• Requires an additional code to specify the nature of the adverse effect or complication (e.g., worsening of ADHD symptoms).
• Only use for psychostimulants other than methylphenidate (T43.61-) or amphetamines (T43.62-).
• The "D" seventh character signifies a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
