Underdosing of unsp hormones and synthetic sub, sequela

This code signifies a long-term consequence or complication arising from a patient's insufficient intake or administration of an unspecified hormone or synthetic substitute. It indicates that the underdosing event itself is no longer active, but its lasting effects are still present and being addressed.

Apply this code when documenting a condition that is a direct result of a past, unresolved underdosing of a hormone, and the specific hormone is not known or documented. Examples include chronic endocrine imbalances or organ damage attributed to prolonged insufficient hormone levels. This code is appropriate for follow-up care related to these lasting effects.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past underdosing event, even if the specific hormone is unknown.
• The "S" seventh character indicates sequela, meaning the residual effect of a previous condition, not the acute underdosing itself.
