A patient is admitted to a hospital rehab unit after acute stroke care was completed elsewhere. Which principal-diagnosis approach is appropriate for the rehab admission?
Select an answer to reveal the explanation.
Short Explanation
Rehab is chapter two of the story, not a reprint of chapter one. You code this admission for why they’re in rehab now—late effects, rehab encounter logic, whatever the guidelines say—not a copy-paste of the old acute stroke principal.
Full Explanation
Subsequent rehab admissions follow guideline families appropriate to rehab and aftercare or late-effect coding rather than automatically repeating the acute inpatient principal diagnosis from a prior facility’s acute stay. Coders base principal diagnosis on the rehab admission documentation and applicable Official Guidelines. Therapy procedure coding does not replace the need for correct diagnosis sequencing on the facility claim.
