Underdosing of electrolytic/caloric/wtr-bal agnt, subs

This code signifies a patient's underdosing of medications or substances crucial for maintaining electrolyte balance, caloric intake, or hydration, and the patient is receiving active treatment for the underdosing's effects. It indicates that the patient is beyond the initial phase of care for this specific underdosing event.

Use this code when a patient presents for follow-up care, monitoring, or further treatment related to insufficient intake or administration of agents like potassium, sodium, glucose solutions, or intravenous fluids. This applies to situations where the underdosing has already been identified and is being managed.

• Assign this code as a secondary diagnosis, with the primary diagnosis reflecting the condition caused by the underdosing.
• Ensure documentation clearly states "underdosing" and specifies the type of agent involved.
• The "D" seventh character indicates subsequent encounter, meaning the patient is receiving ongoing care for the underdosing event.
