Radiology Coding in ICD-10: A Primer
Why? These practices often depend on documentation from referring physicians who may or may not include the specificity necessary to justify medical necessity for a particular test, says Betty Hovey, CPC, COC, CPB, CPMA, CPC-I, CPCD, director of ICD-10 development and training at the American Academy of Professional Coders (AAPC). This is problematic today in ICD-9, and it will become even more troublesome in ICD-10 when the code set demands more specific information. Hovey says radiology practices should focus on obtaining more specific documentation for the following diagnoses:
1. Bone fractures. Referring physicians must document the following (Note: Some fractures don’t require all of this documentation, but many of them do):
For example, the following diagnostic statement is appropriate for an x-ray performed for a patella fracture: Displaced longitudinal fracture of right patella, subsequent encounter for closed fracture with nonunion.

2. Limb pain. In ICD-9, limb pain maps to code 729.5. However, in ICD-10, referring physicians must specify the specific limb, where the pain occurs on that limb, and whether it is the right or left limb. For example, ICD-10 code M79.632 denotes pain in the left forearm.
3. Abdominal pain. Referring physicians must document the specific location of that pain (i.e., right upper quadrant, left upper quadrant, epigastric, right lower quadrant, left lower quadrant, periumbilic, or generalized abdominal pain). Ask physicians to distinguish between acute abdominal pain, abdominal tenderness, rebound abdominal tenderness, colic, and pelvic pain.
4. Congestive heart failure (CHF). Referring physicians must document the type of heart failure (i.e., systolic, diastolic, or combined) and whether it’s acute, chronic, or acute on chronic. For example, ICD-10 code I50.32 denotes chronic diastolic congestive heart failure.
5. Osteoarthritis. Referring physicians must document the specific anatomical location as well as laterality. The American Academy of Orthopaedic Surgeons provides more information on how to code and document this diagnosis properly in ICD-10.
