- Osteopoikilosis
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

Clinical InformationClinical
Chondrodysplasia Punctata
a heterogeneous group of bone dysplasias, the common character of which is stippling of the epiphyses in infancy. the group includes a severe autosomal recessive form (chondrodysplasia punctata, rhizomelic), an autosomal dominant form (conradi-hunermann syndrome), and a milder x-linked form. metabolic defects associated with impaired peroxisomes are present only in the rhizomelic form.Osteopoikilosis
an asymptomatic, autosomal dominant trait in which pea-sized sclerotic spots, prominent in the metaphyseal area, are accompanied by unique cutaneous lesions. these are yellowish papules or plaques with increased elastin content. (from cecil textbook of medicine, 19th ed, pp1434-35)Synostosis
a union between adjacent bones or parts of a single bone formed by osseous material, such as ossified connecting cartilage or fibrous tissue. (dorland, 27th ed)
Patient EducationClinical
Birth Defects
A birth defect is a problem that happens while a baby is developing in the mother's body. Most birth defects happen during the first 3 months of pregnancy. One out of every 33 babies in the United States is born with a birth defect.

Questions About Q78.8Overview
What is the ICD-10 code for other specified osteochondrodysplasias?
The ICD-10-CM code for other specified osteochondrodysplasias is Q78.8 (sometimes written as Q788). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is Q78.8 (Other osteochondrodysplasias) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other specified osteochondrodysplasias on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does Q78.8 group to?
When other specified osteochondrodysplasias is the principal diagnosis on an inpatient stay, it groups to MS-DRG 564, 566, 565, with relative weights from 0.7374 to 1.4909 depending on complications. Higher weights mean higher Medicare reimbursement.
Is Q78.8 exempt from POA reporting?
Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for other specified osteochondrodysplasias on inpatient claims. The code appears in the Congenital malformations and deformations of the musculoskeletal system (Q65-Q79) range of the CMS exempt list.
What is the ICD-9 equivalent of Q78.8?
Under the General Equivalence Mappings, other specified osteochondrodysplasias converts to ICD-9-CM 756.53 (osteopoikilosis) and 756.59 (osteodystrophy NEC). The mapping is approximate, so confirm the match fits the documentation.
