Adverse effect of skeletal muscle relaxants, init encntr

This code signifies an undesirable or harmful reaction occurring as a direct result of the proper administration of a skeletal muscle relaxant, also known as a neuromuscular blocking agent. These effects are not due to overdose or poisoning, but rather an expected or unexpected adverse reaction to the drug itself.

Apply this code when a patient experiences an adverse effect from a skeletal muscle relaxant, such as respiratory depression, prolonged paralysis, or anaphylaxis, during their initial presentation for treatment of this reaction. This is appropriate for reactions to medications like succinylcholine, rocuronium, or vecuronium when used therapeutically.

• Always sequence this code first, followed by codes for the specific manifestation of the adverse effect.
• Ensure documentation clearly states the reaction is an "adverse effect" and not an overdose or poisoning.
• Verify the encounter is the "initial encounter" for the adverse effect, as subsequent encounters will require a different seventh character.
