About coding antibody titer elevated

The ICD-10-CM code for antibody titer elevated is R76.0 (Raised antibody titer).

Within R76 (other abnormal immunological findings in serum), R76.0 is specifically for raised antibody titer. Related codes cover nonspecific reaction to test for tuberculosis (R76.1), other specified abnormal immunological findings in serum (R76.8) and abnormal immunological finding in serum, unspecified (R76.9).

Don't report R76.0 together with the conditions in its Excludes1 note: isoimmunization in pregnancy (O36.0-O36.1) and isoimmunization affecting newborn (P55.-).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

Don't confuse with (Excludes1 for R76.0)

  • isoimmunization in pregnancy (O36.0-O36.1)
  • isoimmunization affecting newborn (P55.-)
