Answer: B
M05.49 is the appropriate code for this case because it codes for “Rheumatoid myopathy with rheumatoid arthritis of multiple sites”. This is the diagnosis in this patient.
Option A is not correct because M05.55 is used to code rheumatoid polyneuropathy with rheumatoid arthritis of the hip which is not the diagnosis here.
Option C is not correct because M05.54 codes for rheumatoid polyneuropathy with rheumatoid arthritis of the hand which is not the diagnosis here.
Option D is not correct because M05.34 codes for rheumatoid heart disease with rheumatoid arthritis of the hand which is not the diagnosis here.
