Can CPT 73562 and 73565 be billed together?

Editorial team Published on

No, CPT codes 73562 and 73565 generally cannot be billed together because 73565 (standing AP view of both knees) is bundled with other specific knee X-ray codes under National Correct Coding Initiative (NCCI) edits.

Coding Rules and Billing Guidelines

  • Stand-Alone Nature: Code 73565 is meant to be a single, standalone bilateral standing view. According to compliance guidelines from resources like the AAPC Knowledge Center, if additional diagnostic views are performed alongside a standing AP bilateral image, you should count the total views per knee and assign the appropriate comprehensive code instead of billing 73565 separately.
  • Mutual Exclusivity: NCCI edit tables classify these codes as mutually exclusive or bundled, meaning reporting them together on the same date of service typically results in a claim denial.
  • Correct Alternative: If a patient requires a 3-view exam on one knee (such as CPT Code 73562) along with separate imaging for the other side, coders usually roll the total views into a higher-view count code for the symptomatic side (like 73564) or code the individual separate views with appropriate site modifiers (-RT or -LT) rather than combining 73562 and 73565.

Does CPT code 73562 need a modifier?

Whether CPT code 73562 (3-view knee X-ray) needs a modifier depends entirely on how the service is performed, the location of the service, and the bilateral nature of the exam.

When You Do Not Need a Modifier

If you perform a standard, unilateral 3-view X-ray of a single knee in a global setting (where the same entity owns the equipment and provides the interpretation), no modifier is required.

Common Modifiers Used with 73562

You may need to append specific modifiers based on these clinical and billing scenarios:

  • Laterality Modifiers (RT or LT): Used to designate the right or left knee. Depending on the payer, you may report the code on two separate lines with RT and LT for bilateral procedures, or use separate lines with specific laterality.
  • Bilateral Modifier (50): Used if both knees are imaged with the exact same number of views during the same session, provided the payer accepts modifier 50 on a single claim line rather than separate RT/LT lines.
  • Professional Component (26): Appended if the physician or radiologist is only interpreting the X-ray film and does not own the equipment or facility.
  • Technical Component (TC): Appended if the facility or clinic is billing only for the equipment, image capture, and technologist time, separate from the physician's interpretation.
  • Distinct Procedural Service (59 / XE, XP, XS, XU): Rarely required, but used if a separate, distinct knee X-ray exam is performed on the same day for a completely separate problem.

Note: Always check your specific commercial payer guidelines or Medicare Administrative Contractor (MAC) Local Coverage Determination (LCD), as billing rules for bilateral positioning and separate component reporting vary widely.

What is the description of CPT code 73562?

CPT code 73562 describes a radiologic examination of the knee with exactly three views.

Overview and Details

  • Official Descriptor: Radiologic examination, knee; 3 views.
  • Common Name: Knee X-ray (3 views).
  • Primary Purpose: To evaluate the knee joint for fractures, dislocations, arthritis, swelling, or unexplained pain.
  • Maintained By: American Medical Association (AMA).

Related Knee X-Ray Codes

  • 73560: Radiologic examination, knee; 1 or 2 views.
  • 73564: Radiologic examination, knee; 4 or more views.
  • 73565: Radiologic examination, knee; both knees, standing, anteroposterior.

What is the description of CPT code 73565?

The official CPT description for code 73565 is "Radiologic examination, knee; both knees, standing, anteroposterior".

Key Details and Usage Rules

  • Anatomical Coverage: It describes a single bilateral weight-bearing X-ray of both knees taken from the front (anteroposterior or AP view) while the patient is standing.
  • No Modifiers Needed: Because the code is inherently bilateral, you should not append modifiers like RT, LT, or 50.
  • Stand-Alone Restriction: Use this code only when the standing AP view is the sole study performed. If additional non-standing or multi-view exams are ordered for the knees, code instead by the total individual view counts (such as 73560, 73562, or 73564) rather than using 73565.

Can these CPT codes be billed together?

Whether two CPT codes can be billed together depends on National Correct Coding Initiative (NCCI) edits, whether the codes are bundled, and if the services are separate and distinct.

You did not list the specific CPT codes you want to check.

How to Check Code Combinations

  • NCCI Edits: Check the CMS NCCI Tool to see if the pair has a column 1/column 2 restriction.
  • Modifiers: Some codes can be billed together with an appropriate modifier (like Modifier 25 or 59) if the documentation shows a separate, distinct service.
  • Bundling Rules: If one procedure inherently includes the other or shares the same anatomical site as a "separate procedure," they generally cannot be unbundled.

Can 73565 and 73562 be billed together?

No, CPT codes 73565 and 73562 cannot be billed together.

Coding Rules

  • NCCI Edits: National Correct Coding Initiative (NCCI) guidelines bundle unilateral knee X-ray codes (like 73560 or 73562) with the bilateral standing AP code (73565). Modifiers are generally not allowed to override this pairing.
  • Stand-Alone Nature: Code 73565 (standing AP of both knees) is meant to be reported only when it is performed by itself as a distinct procedure.
  • Total View Count Method: If a standing view is combined with other unilateral views (such as a 3-view series), you should instead count the total number of views performed for the session and code them under the appropriate comprehensive view category (such as 73562 for 3 views or 73564 for 4 or more views).

Can you bill 73564 bilaterally?

Yes, you can bill CPT Code 73564 bilaterally if both knees receive a complete examination with four or more views and documentation supports medical necessity for each side.

Billing Rules for Bilateral 73564

  • View Count: Each knee must independently have at least four documented views in the radiology report.
  • Comparison vs. Diagnostic: You cannot bill for the opposite side if it was imaged strictly for routine comparison without an explicit order and documented medical necessity.
  • Modifier 50: Many insurance payers and Medicare require you to report CPT Code 73564 on a single line with Modifier 50 to indicate a bilateral procedure.
  • Laterality Modifiers: Some alternative payers prefer two separate line items using RT (right) and LT (left) modifiers instead of Modifier 50.
  • Standing AP Exception: If the only bilateral study performed is a single standing anteroposterior view, use CPT Code 73565 instead of a bilateral 73564.

What does CPT code 73560 represent?

CPT code 73560 represents a radiologic examination (X-ray) of a single knee utilizing one or two views.

Overview of CPT 73560

  • Description: X-ray of one knee with 1 to 2 images taken.
  • Purpose: To check for bone fractures, joint swelling, pain, or monitoring previous injuries.
  • Section: Diagnostic Radiology (Diagnostic Imaging).

Related View-Count Codes

  • CPT 73562: Knee X-ray with exactly 3 views.
  • CPT 73564: Knee X-ray with 4 or more views.
  • CPT 73565: Bilateral knee X-ray (standing, both knees).

Billing & Coding Guidance

  • Laterality: Requires anatomical modifiers like RT (right) or LT (left) for unilateral procedures.
  • Documentation: The medical report must explicitly state the exact number of views performed to justify the selected code.

What is the difference between CPT 78451 and 78452?

The primary difference between CPT code 78451 and CPT code 78452 is the number of imaging studies (or phases) performed during a Single-Photon Emission Computed Tomography (SPECT) myocardial perfusion scan.

Core Differences

  • CPT 78451 (Single Study): Used when the myocardial perfusion scan is performed only once—either strictly at rest or strictly under stress (exercise or pharmacologic). It involves a single dose of a radiopharmaceutical.
  • CPT 78452 (Multiple Studies): Used when two or more imaging studies are performed, most commonly a combination of both rest and stress phases. It typically requires two separate radiopharmaceutical doses.

Key Details to Remember

  • Same vs. Separate Days: CPT 78452 is still the correct code to use if the rest and stress portions are performed on separate dates; you should never bill 78451 twice.
  • Both Share Technology: Both codes utilize SPECT tomographic imaging and include evaluation for wall motion and ejection fraction when performed.
  • Avoid Billing Errors: Mixing up single-phase and multi-phase codes is a frequent cause of insurance claim denials in nuclear cardiology.

What is the description of CPT code 73050?

CPT code 73050 describes a radiologic examination of the acromioclavicular (AC) joints, bilateral, with or without weighted distraction.

Overview

  • Procedure Type: Diagnostic radiology x-ray of the upper extremities.
  • Anatomy: Both the left and right acromioclavicular joints (where the collarbone meets the shoulder blade).
  • Technique: May include standard views or weighted views (where the patient holds weights to pull down on the arms and reveal joint separation or ligament damage).
  • Usage: Ordered by doctors to check for shoulder injuries, separation, arthritis, or other joint diseases.

You can look up further details or billing rules on the AAPC CPT 73050 Guide.
