UPDATE 2026
What information is required to accurately code osteoarthritis in ICD-10-CM? -
Answers Whether the osteoarthritis is primary, secondary, post-traumatic, the site and
laterality.
Rationale: To accurately code osteoarthritis in ICD-10-CM, the documentation needs
to include whether the arthritis is primary, secondary, post-traumatic, the site and
laterality (right/left).
What is the acromion? - Answers Extension of the scapula
Rationale: The acromion is an extension of the scapula that meets the clavicle at the
shoulder to form the acromioclavicular joint.
Most of the codes in ICD-10-CM Chapter 13 Diseases of the Musculoskeletal System
and Connective Tissue have site and laterality designations. According to ICD-10-CM
guidelines what is considered the site? - Answers The site may be the bone, joint or
muscle involved.
Rationale: According to ICD-10-CM guideline I.C.13.a., the site may be the bone,
joint or muscle involved.
A patient has a greenstick fracture of the right radial shaft. It is treated by surgically
placing a bone plate on the distal radial shaft. What ICD-10-CM code is reported? -
Answers S52.311A
Rationale: A greenstick fracture occurs when the bone does not break completely
through, and the bone does not protrude through the skin; this is a closed fracture. The
treatment to fix the fracture is an open approach to expose the bone to insert the plate
across the fracture site; however, the fracture care treatment is not considered when
coding for the diagnosis. In the ICD-10-CM Alphabetic Index look for Fracture,
traumatic/radius/shaft/greenstick S52.31-. In ICD-10-CM codes are specific for
laterality (left, right) and the episode of care. Check the Tabular List and seven
characters are needed to complete the code. Right radial shaft is indicated in the
question and because the encounter is being treated surgically, this meets the
, definition of initial encounter or active treatment (See ICD-10-CM guideline
I.C.19.a.). The complete code is S52.311A.
What is segmental instrumentation? - Answers A spinal fixation device attached at
each end of a rod and at additional bony attachment
Rationale: Segmental instrumentation of the spine is a procedure used to repair a
spinal defect where the fixation device is attached in at least three places: at each end
of the construct (rod) and at least one additional interposed bony attachment.
A patient presented with a closed, displaced supracondylar fracture of the left elbow.
After conscious sedation, the left upper extremity was draped and closed reduction
was performed, achieving anatomical reduction of the fracture. The elbow was then
prepped and with the use of fluoroscopic guidance, two K-wires were directed
crossing the fracture site and piercing the medial cortex of the left distal humerus.
Stable reduction was obtained, with full flexion and extension. K-wires were bent and
cut at a 90-degree angle. Telfa padding and splint were applied. What CPT® code(s)
is/are reported? - Answers 24538-LT
Rationale: This is a supracondylar fracture of the elbow repaired by percutaneous
fixation. In the CPT® Index look for Fracture/Humerus/Supracondylar/Percutaneous
Fixation and you are referred to 24538. Modifier LT is appended to indicate the
procedure is performed on the left side. The application of the first cast or splint is
included in the fracture codes. See the guidelines before Application of Casts and
Strapping in your CPT® codebook. Fluoroscopy guidance 76000, is listed as a
separate procedure; therefore, is included in the procedure.
A 27 year-old presents with right-sided thoracic myofascial pain. A 25-gauge 1.5-inch
needle on a 10 cc controlled syringe with 0.25% bupivacaine was used. After negative
aspiration, 2 cc were injected into each trigger point. A total of four trigger points
were injected. A total of 8 cc of bupivacaine was used on the rhomboid major,
rhomboid minor, and levator scapular muscles. What CPT® code(s) is/are reported
for this procedure? - Answers 20553
Rationale: In the CPT® Index look for Injection/Trigger Point(s)/Three or More
Muscles. You are referred to 20553. Review the code to verify accuracy. 20553
covers the three muscles (rhomboid major, rhomboid minor and scapular muscles)
