Congenital deformities of hip (Q65) ICD-10-CM
The Q65 code range covers congenital deformities of hip with 19 ICD-10-CM diagnosis codes. 15 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the Q65 range.
Coxa Valga
Hip deformity in which the angle between the femoral neck and its shaft is increased. It may be congenital, acquired, or developmental.
Craniosynostoses
Premature closure of one or more CRANIAL SUTURES. It often results in plagiocephaly. Craniosynostoses that involve multiple sutures are sometimes associated with congenital syndromes such as ACROCEPHALOSYNDACTYLIA; and CRANIOFACIAL DYSOSTOSIS.
Plagiocephaly
The condition characterized by uneven or irregular shape of the head often in parallelogram shape with a flat spot on the back or one side of the head. It can either result from the premature CRANIAL SUTURE closure (CRANIOSYNOSTOSIS) or from external forces (NONSYNOSTOTIC PLAGIOCEPHALY).
Plagiocephaly, Nonsynostotic
A deformity of the SKULL that is not due to bone fusion (SYNOSTOSIS), such as craniosynostoses, and is characterized by an asymmetric skull and face. It is observed with an increased frequency in INFANTS after the adoption of supine sleeping recommendations to prevent SUDDEN INFANT DEATH SYNDROME.
About the Q65 Code Range
The ICD-10 code section Q65 covers congenital deformities of the hip, a range of conditions present at birth that affect the hip joint's structure and stability. These codes are used to classify various specific abnormalities such as dislocations, partial dislocations, instability, and structural deformities of one or both hips.
This section includes codes for congenital dislocation of the hip—either unilateral (like Q65.01 for the right hip and Q65.02 for the left hip) or bilateral (Q65.1)—which may also be known by terms like congenital subluxation or bipolar congenital dislocation of hip. Partial dislocations or subluxations are coded in Q65.3 series, and Q65.6 denotes congenital unstable hip, also referred to as a dislocatable or subluxatable hip. Structural deformities such as coxa valga (Q65.81) and coxa vara (Q65.82) have designated codes. Coders use these specific codes to accurately capture the precise type of hip abnormality, ensuring clarity when documenting conditions like developmental dysplasia or other rare congenital hip disorders.
