Adverse effect of tramadol, initial encounter

This code signifies an undesirable or harmful reaction experienced by a patient due to the therapeutic use of tramadol. These adverse effects are not due to an overdose or poisoning, but rather an unintended consequence of the drug when taken as prescribed or appropriately administered.

Apply this code when a patient presents with symptoms such as nausea, dizziness, constipation, somnolence, or other documented side effects directly attributable to their prescribed tramadol. This code is appropriate for the initial visit where the adverse effect is first identified and treated.

• Ensure documentation clearly states the reaction is an adverse effect of tramadol, not an overdose or poisoning.
• Always sequence this code first, followed by codes for the specific manifestation(s) of the adverse effect.
• Verify that the encounter is the initial treatment for this specific adverse effect to justify the "A" seventh character.
