Description

A cranial orthosis used in the treatment of plagiocephaly is a device intended for medical purposes to apply pressure to prominent regions of an infant's cranium in order to improve cranial symmetry and/or shape.

Criteria

Non-synostotic Plagiocephaly

Cranial orthotic devices used in the treatment of moderate-to-severe non-synostotic plagiocephaly may be considered medically necessary when ALL of the following criteria are met:

The infant must have tried and failed conservative therapy (i.e., repositioning) for a minimum of two (2) months; and
The infant must be three (3) - 18 months of age; and
Cranial asymmetry is documented by EITHER of the following:
- Moderate to severe plagiocephaly in ONE of the following anthropometric dimensions (Table 1):
  - Cranial vault; or
  - Cranial base; or
  - Orbitotragial depth; or
- Cephalic index measurement is two (2) standard deviations (SD) above or below the mean (Table 2)

Cranial orthosis is considered cosmetic and therefore non-covered when used in the treatment of non-synostotic plagiocephaly with mild deformity and/or when a minimum trial period of two (2) months of conservative therapy has not been tried.

Cranial orthotic devices for non-synostotic plagiocephaly not meeting the criteria as indicated in this policy is considered not medically necessary.

Synostotic Plagiocephaly

Cranial orthotic devices used in the post-operative treatment of synostotic plagiocephaly may be considered medically necessary for infants with moderate to severe residual plagiocephaly after surgical correction when cranial asymmetry is documented by ANY of the following:

Moderate to severe plagiocephaly in ONE of the following anthropometric dimensions (Table 1):
- Cranial vault; or
- Cranial base; or
- Orbitotragial depth; or
Cephalic index measurement is two (2) standard deviations (SD) above or below the mean (Table 2).

Cranial orthotic devices for synostotic plagiocephaly not meeting the criteria as indicated in this policy is considered not medically necessary

Determination of Severity of Plagiocephaly

Determination of the severity of plagiocephaly requires precise measurements of the skull using either the
cephalic index or anthropomorphic measurements.

Table 1

Specifications for Taking Anthropometric Measurements

	Comparative Cranial Landmarks
Cranial Vault	Left frontozygomatic point (fz) to right euryon (eu) minus right frontozygomatic point (fz) to left euryon (eu)
Cranial Base	Subnasal point (sn) to left tragus (t) minus subnasal pint (sn) to right tragus (t)
Orbitotragial Depth	Left exocanthion point (ex) to left tragus (t) minus right exocanthion point (ex) to right tragus (t)

Moderate to severe plagiocephaly is defined as one of the following:
Cranial base (sn – t): >= 6 mm difference between left and right measurements

Cranial vault (fz – contralateral eu): >= 8 mm difference between left and right measurements

Obitotragial depth (ex – t): >= 4 mm difference between left and right measurements

Table 2

Cephalic index: Head width (eu-eu) x 100

Head length (g-op)

Moderate to severe plagiocephaly is defined as a cephalic index two standard deviations above or below the mean. Infants with deformational scaphocephaly will have a lower cephalic index due to a very long and narrow skull deformity. Infants with deformational brachycephaly will have an increased cephalic index due to a very wide and short skull deformity.

Gender	Age	-2SD	-1SD	Mean	+1SD	+2SD
Male	16 days - 6 months	63.7	68.7	73.7	78.7	83.7
	6 – 12 months	64.8	64.8	78	84.6	91.2
Female	16 days - 6 months	63.9	63.9	73.3	78	82.7
	6 – 12 months	69.5	69.5	78.5	83	87.5

Assessment of plagiocephaly may be based on anthropomorphic measures of the head, using anatomical and bony landmarks. However, there is no accepted minimum objective level of asymmetry for a plagiocephaly diagnosis. The following table presents normative values and the mean pretreatment asymmetries reported in large case series. These may be useful in determining if a significant variation from normal is present.
