Q: Our facility has a question about how other hospitals address this scenario: Patient is discharged to home (discharge status code 01). No documentation exists in the medical record to support post-acute care. Several months later, our Medicare Administrative Contractor (MAC) notifies us that the patient indeed went to post-acute care after discharge. The MAC retracts our entire payment. We need to resubmit the claim with the correct discharge status code. We are reluctant to do so because nothing in the medical record supports the post-acute care provided. Are other hospitals amending the record? If so, which department is adding the amended note?
Q: A patient has been diagnosed with peritonsillar cellulitis and oropharyngeal cellulitis. The physician documents that he performed a “needle aspiration of the left peritonsillar abscess.” In the body of the operative report, the physician states, “An 18-gauge needle was inserted and 1 cc of pus was aspirated. This was sent for aerobic, anaerobic, C&S [culture & sensitivity], and gram stain. I then put the 18-gauge needle in again and multiple passes were obtained without any aspirate.” Because ICD-9-CM does not include a code for “aspiration of peritonsillar abscess” some coders wanted to use ICD-9-CM procedure code 28.0 (incision and drainage of tonsil and peritonsillar structures) while others want to report code 28.99 (other operations on tonsils and adenoids). Which code is correct?
Our coding experts answer your questions about observation orders, sequencing additional diagnoses, coding for wound care with no-cost skin substitute, and reporting cardiac rehabilitation and physical therapy together.
Q: In my facility, we are supposed to send an email to our physician advisor (PA) and to administration if a query is not answered within a week. However, this policy doesn’t work well because administration does not do anything with that information, and the PA doesn’t have time to review unanswered queries. Do you have any suggestions concerning when to let a query go unanswered?
QUESTION: A physician documents in an operative report debridement of a necrotic muscle (not due to an open wound). Must the physician also document how the muscle is removed to report ICD-9-CM procedure code 83.45 (other myectomy)? Is this considered excisional or nonexcisional debridement? What documentation is required to code the removal of a necrotic portion of a muscle?
