Poisoning by methamphetamines, assault, sequela

This code indicates a long-term consequence or complication arising from a methamphetamine poisoning that occurred as a result of an assault. The initial acute poisoning event has resolved, but the patient is now experiencing residual effects directly attributable to that past incident.

Apply this code when documenting conditions such as chronic organ damage, neurological deficits, or persistent psychological sequelae that are directly linked to a prior methamphetamine poisoning sustained during an assault. This code is appropriate for follow-up encounters where the sequela, not the acute poisoning, is the focus of treatment.

• Always sequence the sequela code first, followed by any codes for the specific manifestation of the sequela.
• Ensure documentation clearly links the current condition to a past methamphetamine poisoning by assault.
• Do not use for acute poisoning events; this code is exclusively for residual effects after the acute phase has passed.
