Adverse effect of skeletal muscle relaxants, sequela

This code signifies a long-term or residual condition resulting from a previous adverse reaction to skeletal muscle relaxants, specifically neuromuscular blocking agents. These sequelae are persistent health problems that arose directly from the initial drug-related harm, even after the acute phase of the adverse effect has resolved.

Use this code when documenting a chronic or permanent condition that is a direct consequence of an adverse effect from a neuromuscular blocking agent. Examples include persistent muscle weakness, nerve damage, or other lasting complications attributed to the prior drug reaction. This code is appropriate when the acute adverse effect is no longer present but its lasting impact remains.

• Always sequence this code after the code(s) for the specific sequela (e.g., muscle weakness, neuropathy).
• Ensure documentation clearly links the current condition as a direct result of a past adverse effect from a skeletal muscle relaxant.
• Distinguish from acute adverse effects, which would use the 'A' or 'D' seventh character.
