Radiology Coding Services

From simple X-Rays to Fluoroscopy, Computed Tomography and Magnetic Resonance Imaging, Radiology practices perform essential tests. Imaging diagnostics and procedures have become crucial in modern healthcare. But coding intricacies and a lack of trained medical coders specializing in radiology have hit many imaging centers and laboratories hard. As a result, Radiology centers have turned to specialized Radiology coding services for improved billing and reduced claim denials. Moreover, the cost savings offered by some Radiology coding companies have made outsourcing a compelling argument.

Before we talk about how our Radiology coding support helps practices across the US, let us looking at the intricate landscape of imaging center coding.

Medical Coding Intricacies in Radiology

These are the CPT® (Current Procedural Terminology) coding ranges for various Radiology procedures:

  • 70010-76499 Diagnostic Radiology (Diagnostic Imaging) Procedures
  • 76506-76999 Diagnostic Ultrasound Procedures
  • 77001-77022 Radiologic Guidance
  • 77046-77067 Breast, Mammography
  • 77071-77092 Bone/Joint Studies
  • 77261-77799 Radiation Oncology Treatment
  • 78012-79999 Nuclear Medicine Procedures

Within this segment, codes 70010 to 77092 are relevant to Radiology Practices and Imaging Lab Centers. Our coders have reviewed all the new CPT® codes for 2024, including the coding and reporting guideline changes with the CPT Assistant Updates, as well as the annual CPT updates.

sunknowledge advantage



The American Medical Association (AMA) announced 2021 CPT code set changes, stating 329 editorial changes, 206 new codes, 54 deletions, and 69Radiology Coding Services revisions (AMA, 2020). Many of the editorial changes are the result of the 2021 E/M office visit code revisions. However, there are editorial changes, such as guideline or parenthetical note changes, throughout the CPT Radiology, Surgery, Pathology and Laboratory, Medicine, and Category III Codes.

For this reason, coding teams must carefully review Appendix B and the new guidelines and notes each year. Appendix B contains all code additions, deletions, and revisions found in the manual, but CPT contains other additions because of online updates.

There are also Group Modifiers, Claim Adjustment Reason Codes (CARC) Remittance Advice Remark Codes (RARC) and Medicare Summary Notice (MSN) attached to each. Let us take PET scans for our example:

Billing Codes and Diagnosis for PET Scans:

  • Contractors recommend using the appropriate CPT code from section 60.3.1 for dementia and neurodegenerative diseases.
  • Diagnosis codes for PET Scans for Alzheimer’s Disease (AD) include ICD-10 codes: F03.90, F03.90 plus F05, G30.9, G31.01, G31.9, R41.2, or R41.3.

Denial Prevention and Remittance Advice:

  • Claims submitted with an appropriate CPT code and a diagnosis code outside the specified range will be denied.
  • Contractors advise issuing an Advanced Beneficiary Notice to patients before services if the correct diagnosis code won’t be present on the claim.
  • Remittance advice messages include:
  • Group Code: PR (patient responsibility) with GA modifier, otherwise CO (contractual obligation).
  • CARC: 11
  • RARC: N/A
  • MSN: 16.48

Documentation Requirements for PET Scan Claims:

Medicare contractors stress the importance of maintaining comprehensive information in the beneficiary’s medical record, including:

  • Date of onset of symptoms.
  • Diagnosis of clinical syndrome (normal aging, mild cognitive impairment, or various stages of dementia).
  • Mini mental status exam (MMSE) or similar test score.
  • Presumptive cause (possible, probably, uncertain AD).
  • Results of neuropsychological testing, structural imaging (MRI, CT), and relevant laboratory tests (B12, thyroid hormone).
  • Number and name of prescribed medications.

Billing Changes and Effective Dates:

  • NCD 220.6.20 for Beta Amyloid PET scans has been removed as of October 13, 2023.
  • Coverage determinations are now made by the MACs (Medicare Administrative Contractors).
  • Effective from September 27, 2013, to October 12, 2023, CED is allowed for PET beta amyloid imaging.
  • Claims lacking specific requirements, including condition code 30, value code D4 (FI only), appropriate modifier Q0, ICD-10 dx code Z00.6, PET HCPCS code (78811 or 78814), and specified diagnosis codes, will be returned as unprocessable.


  • Minimal changes in the Radiology Section – two new codes, two deleted, and six revised.
  • AMA revised three codes to include the word “diagnostic,” and added a code for CT thorax, low dose for lung cancer screening.
  • The other new code captures medical physics dose evaluation for radiation exposure.

However, diagnostic codes alone won’t get you paid. They need to be paired with the appropriate HCPCS C, G, Q and R codes for items or services. Here are a few examples:

Dedicated Medical Coding Support for Radiology Centers

We employ certified coders who are experts in coding for radiology lab practices. Be it ICD-10, NCCI edits or place of service codes (POS), our coders have the necessary domain knowledge to ensure optimal billing – no missed or delayed payment and zero denied claims. Our teams have experience of handling high volume coding projects.

Medical coding has two other aspects that we need to talk about:

  1. Its role in establishing medical necessity
  2. Catering to Payer requirements

Moreover, we need to consider documentation management and clear channels of communication – factors that determine the actual impact of correct medical coding.
