Case Studies

Kaye is a previously health 3 year old presenting with 5 days of emesis and new onset of seizures. She was diagnosed on imaging with a posterior fossa mass and obstructive hydrocephalus. Following surgery to remove the mass and perform an ETV, the patient was noted post operatively to have a constellation of symptoms including: mutism, dysphagia, ataxia; and, emotional lability. Documentation indicated that the patient had ‘cerebellar mutism’.

CDI query to the physician, requested clarification on whether posterior fossa syndrome, which includes this constellation of symptoms could be used interchangeably with posterior fossa mutism. Per the physician, posterior fossa mutism is not a diagnosis. Posterior fossa syndrome, the diagnosis indicated in this case, codes to G935 “compression of brain” and carries an SOI of 4, ROM 4. This condition is expected to be temporary and resolve over time. Mutism, which can also be a sequelae of brain tumor excision, can be temporary or permanent. However, the coding of mutism is to R4701 aphasia, which carries an SOI of 3, ROM1.

Alpha is a 20 month old with newly diagnosed acute myeloblastic leukemia. In addition to Alpha’s new oncology diagnosis, as her work up continues and chemotherapy is started, her providers document “risk for tumor lysis syndrome” and the treatments aimed at preventing it. Labs are frequently drawn to monitor this condition. The next day, providers noted metabolic abnormalities of: hyperkalemia, hyperphosphatemia and hyperuricemia. CDI should query the provider to ask if, based on the documented lab values, another diagnosis assignment is indicated.
