acr-o-megal--y - abnormal enlargement of hands, feet, jaw, and/or other extremities, often due to too much GH ( condition of enlarged extremities); The keyword “abduct” (or abduction) can refer to several different clinical scenarios. It commonly refers to the movement of a body part away from the midline, which can present as a joint contracture (abduction contracture), a nerve condition (abducens nerve palsy affecting the eye’s ability to abduct), or procedures involving abductor muscles or abduction splinting.
acr-: From the Greek akron, meaning “extremity” or “end.”
mega-: From the Greek megas, meaning “large” or “great.”
-y: A suffix denoting a “condition” or “process.”
Literal Meaning: The condition of having large extremities.
ICD-10-CM Code(s):
Code Short Title: Explanation
M24.551 / M24.552Contracture, right hip / Contracture, left hip: Used for an abduction contracture of the hip, where the joint is restricted and fixed in an abducted position.
M24.511 / M24.512Contracture, right shoulder / Contracture, left shoulder: Used for an abduction contracture of the shoulder joint.
M24.50Contracture, unspecified joint: Used when an abduction contracture is documented but the specific joint is not identified.
H49.21 / H49.22 Sixth [abducens] nerve palsy, right eye / left eye: The abducens nerve controls the lateral rectus muscle, which abducts the eye. A palsy results in an inability to abduct the eye outward.
M62.40Contracture of muscle, unspecified site: Used if the abduction contracture is strictly muscular rather than involving the joint capsule itself.
R26.2 Difficulty walking, not elsewhere classified: Used as an ancillary code if there is documented functional gait impairment due to an abduction/adduction deformity of the lower extremities.
CPT/HCPCS Code(s):
Code Long Title: Explanation
28240 Tenotomy, lengthening, or release, abductor hallucis muscle: Surgical release or lengthening of the abductor hallucis muscle in the foot, commonly performed to relieve foot pain or correct toe deformities.
WRVU: ~4.41
Assistant Payable: Yes
27256 Treatment of spontaneous hip dislocation (developmental, including congenital or pathological), by abduction, splint or traction; without anesthesia, without manipulation: Non-surgical closed treatment of a hip dislocation utilizing an abduction splint or traction to realign the joint.
WRVU: 4.17
Assistant Payable: Yes
27257 Treatment of spontaneous hip dislocation (developmental, including congenital or pathological), by abduction, splint or traction; with anesthesia, without manipulation: Similar to 27256, but performed under anesthesia.
WRVU: 5.25
Assistant Payable: Yes
L1652 Hip orthosis, bilateral thigh cuffs with adjustable abductor spreader bar, adult size, prefabricated, includes fitting and adjustment: HCPCS code for an adjustable hip abduction brace or orthosis.
WRVU: N/A
Assistant Payable: N/A
Global Periods:
28240: 090 days
27256, 27257: 090 days
L1652: XXX (Not subject to global period rules)
HCC Information:
Uncomplicated joint contractures (M24.5-) and isolated cranial nerve palsies (H49.2-) do not typically risk-adjust under the CMS-HCC model unless they are manifestations of a broader hierarchical condition (such as advanced neuromuscular disease or stroke sequelae).
Exclusives/Inclusives:
ICD-10 M24.5- (Contractures):Excludes1: contracture of muscle without contracture of joint (M62.4-), contracture of tendon (sheath) without contracture of joint (M62.4-), and Dupuytren’s contracture (M72.0).
CPT 28240: Mutually exclusive to comprehensive bunionectomies or major foot reconstructions (e.g., CPT 28292-28299) when performed on the same toe, as the soft tissue release is considered an inclusive component of the primary correction.
CPT 27256 / 27257: Mutually exclusive to one another; do not report together. These are also generally bundled into open hip reductions or arthroplasties if performed on the same hip during the same operative session.
