Reader Question:

Look to 'H' Series for Eustachian Tube Dx

Question: Eustachian tube dysfunction had a specific code in ICD-9 (381.81), but in ICD-10 it does not. My physicians are saying that “Eustachian tube obstruction” (H68.10-) is the closest approximation but ET obstruction is not a commonly used medical term in this specialty. What do you recommend?

Answer: The ICD-10 GEMS map 381.81 (Dysfunction of Eustachian tube) to category H69.8- (Other specified disorders of Eustachian tube) for “other specified disorder.” Your best options are:

  • H69.80 — Other specified disorders of Eustachian tube, unspecified ear
  • H69.81 — Other specified disorders of Eustachian tube, right ear
  • H69.82 — Other specified disorders of Eustachian tube, left ear 
  • H69.83 — Other specified disorders of Eustachian tube, bilateral.
