Myositis in cysticercosis

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

This condition occurs when tapeworm larvae (cysticercus) infect the muscles, causing inflammation and muscle pain. It results from eating undercooked meat contaminated with tapeworm eggs, typically from pork or beef.

Coding Tips

  • •Always code the underlying cysticercosis first (B69.8-) before coding the myositis manifestation, as B69.81 is a manifestation code
  • •Verify documentation specifies muscle involvement; if cysticercosis affects other sites (brain, eye, subcutaneous tissue), use the appropriate B69 subcode instead
