Poisoning by mineralocorticoids and antag, undet, sequela

This code signifies a long-term or residual effect resulting from a poisoning event involving mineralocorticoids or their antagonists, where the intent of the poisoning (e.g., accidental, intentional self-harm, assault) cannot be determined. It indicates that the acute phase of the poisoning has passed, but the patient continues to experience health problems directly attributable to the past exposure.

Use this code when documenting a patient presenting with a chronic condition, organ damage, or other persistent health issues that are a direct consequence of a prior, undetermined poisoning by mineralocorticoids or their antagonists. This applies when the initial acute poisoning event has resolved, but its lasting effects require ongoing medical management.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic kidney disease, adrenal insufficiency).
• Ensure documentation clearly links the current condition to a past poisoning event and explicitly states the undetermined intent.
• Do not use this code for acute poisoning; use the appropriate acute poisoning code with the 7th character "A" for initial encounter.
