Question: One of our coders says we can no longer report diagnosis 333.7. What should we report instead?

Answer: ICD-9 2007 adds fifth-digit specificity to 333.7x (Acquired torsion dystonia). Your new choices for dystonia coding are 333.71 (Athetoid cerebral palsy), 333.72 (Acute dystonia due to drugs), and 333.79 (Other acquired torsion dystonia).

Rationale: ICD-9 created these sub-codes to help physicians report more specific diagnoses. How often you rely on each of the new codes will depend on your practice's patient population.
