Underdosing of vitamins, initial encounter

This code signifies a patient's insufficient intake or absorption of essential vitamins, leading to potential deficiency symptoms or health complications. It indicates that the underdosing event is currently being treated or investigated.

Apply this code when a patient presents with symptoms directly attributable to a lack of vitamin intake, such as scurvy due to vitamin C deficiency or rickets from insufficient vitamin D. It is appropriate for initial evaluations and treatments related to the underdosing.

• Always sequence this code after the specific vitamin deficiency (e.g., E54 for Vitamin C deficiency).
• Ensure documentation clearly states the underdosing is the cause of the patient's condition.
• Do not use for intentional self-harm or poisoning; those scenarios have different codes.
