ICD-10 Code for Rh
The ICD-10-CM 2027 alphabetic index lists rh with the subterms below. More specific codes depend on the details documented, as listed in the official index (3 codes, 1 billable).
Index entries for Rh
- hemolytic disease (newborn) –
P55.0 - incompatibility, immunization or sensitization
- negative mother affecting newborn –
P55.0 - titer elevated – see Complication(s), transfusion, incompatibility reaction, Rh (factor)
- transfusion reaction – see Complication(s), transfusion, incompatibility reaction, Rh (factor)
How to choose the right code
Start with the main term, then pick the indented subterm that matches the documentation (type, cause, site, laterality, episode of care). Always confirm the code in the tabular list: follow its Excludes1/Excludes2, “code first” and “use additional code” notes, and add a 7th character where required.
