Inaccurate or non-specific diagnosis coding can adversely affect your reimbursement of medical claims.
Many categories of the ICD-9 contain codes that represent the
non-specified site of a certain neoplasm. The are typically indicated
with a “9” as the last digit of the code.
Even
though all of these codes are viable, accepted diagnoses, many payers,
especially Medicare, highly encourage the use of the more “site
specific” codes. Failure to be specific can in some instances cause
Medical Necessity denials as the non-specific codes may not be listed as
acceptable in the payers' Medical Policies. Also, if audited, a
discrepancy between the treating diagnosis in the medical chart and the
diagnosis submitted on a claim, could cause payment reversals and money
due back to the payer.
In all medical specialties, the patient medical record should dictate what services are billed and the diagnoses used.
One
specialty example is Radiation Oncology. The prescriptions for
Radiation Therapy Treatment Courses are very site specific, so this
information is one of the most helpful tools in proper diagnosis coding
when used in conjunction with patient data the medical staff has entered
into the medical record.
In
any specialty, but quite frequently in Radiation Oncology, a patient
can have numerous diagnoses that require treatment. In these instances,
it is especially important to indicate the proper diagnosis priority on
your services. The priority one diagnosis should always be the current
treating diagnosis for the service you are billing.
Another frequent situation in Radiation Oncology billing
arises when treating a patient for metastatic disease. The metastatic
treatment site will be listed as the priority one diagnosis with the
primary original site diagnosis listed as the second.
Other
specialties would follow a similar scenario if they were treating a
complication diagnosis, billed as priority one, from an initial
diagnosis, billed as priority two.
A medical billing system with comprehensive ICD -9 and ICD-10 code files, such as Iridium Suite can assist your office in accurately billing the most specific diagnoses for the patients in your practice.
