Coding and billing in the pediatric intensive care unit.

Physicians need to be proficient in their use of CPT codes and ICD-9 codes. They must participate actively and be knowledgeable of their billing process. An organized approach to coding and billing has been suggested by the American Academy of Pediatrics, as outlined in the following box. Physicians are ultimately responsible for any bill submitted in their name. Therefore, close scrutiny of the coding and billing procedures is paramount. Even if mistakes are made in the billing process beyond physicians' input, physicians still may be held responsible. If physicians do their own coding, the bills become more accurate, which can result in higher reimbursement. Physicians also should have a functional compliance plan in place, whether practicing in a large faculty group practice or practicing solo, with the ability to audit the coding and billing process and respond to variances if they are found. By being more involved in the process, physicians can have a more efficient billing system that avoids the potential for fraud and abuse and improves collections.
