Type A behavior pattern

This code identifies a personality and behavioral pattern characterized by excessive competitiveness, time urgency, hostility, and an aggressive drive. Individuals exhibiting this pattern often experience chronic stress and are prone to overworking and impatience. It is considered a psychological risk factor for certain health conditions, particularly cardiovascular disease.

This code is appropriate when a physician explicitly documents a diagnosis of "Type A behavior pattern" or similar terminology indicating these specific behavioral traits. It may be used in conjunction with other diagnoses, such as stress-related disorders or cardiovascular conditions, where the Type A pattern is considered a contributing factor. It should not be used for general stress or anxiety without specific documentation of this behavioral pattern.

• Ensure the physician's documentation clearly specifies "Type A behavior pattern" or equivalent.
• Do not assign this code based solely on symptoms of stress or anxiety without a formal diagnosis of the pattern.
• Consider sequencing this code as a secondary diagnosis when it contributes to or is associated with a primary medical condition.
