ICD-10 Clinic - Book 14: Poisoning and Z Codes

Same drug, three completely different codings. This book teaches the Table of Drugs and Chemicals and the three situations it separates: an adverse effect of a medicine taken correctly, a poisoning where something went wrong with the taking, and an underdosing where the patient took less than prescribed. Each has its own sequencing rule, and the first two are exact opposites, which is precisely what examinations test. It also covers complications of medical and surgical care and the documented link they require. Part two is the whole Z code chapter: status against history, screening against follow-up against aftercare, and which Z codes may lead a record. Fifteen exercises with worked answers.

Twenty-five A4 pages, in full colour. Written in short sentences and plain English, for readers whose first language is not English and clearer for everyone else because of it.

Every ICD-10-CM code in this book was verified against the official 2026 code set before the file was made. Instant PDF download. By M.R. Sterling.
