Code Classification

  • Congenital malformations, deformations and chromosomal abnormalities
    (Q00-Q99)
    • Cleft lip and cleft palate
      (Q35-Q37)
      • Cleft palate
        (Q35)

Q35.9 is a billable diagnosis code used to specify a medical diagnosis of cleft palate, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.

Unspecified diagnosis codes like Q35.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Classification

Clinical Information

  • Cleft Palate

    congenital fissure of the soft and/or hard palate, due to faulty fusion.
  • Palatal Obturators

    appliances that close a cleft or fissure of the palate.
  • Cleft Palate

    a congenital abnormality consisting of a fissure in the midline of the hard and/or soft palate; it is the result of the failure of the two sides of the palate to fuse during embryonic development.
  • Palatorrhaphy|Cleft Palate Repair|Cleft palate repair

    the surgical repair of a cleft palate by approximation of the intact tissues surrounding the defect.
  • TBX22 wt Allele|ABERS|CLPA|CPX|Cleft Palate and/or Ankyloglossia Gene|T-Box 22 wt Allele|TBXX|dJ795G23.1

    human tbx22 wild-type allele is located in the vicinity of xq21.1 and is approximately 21 kb in length. this allele, which encodes t-box transcription factor tbx22 protein, plays a role in palate development. mutation of the gene is associated with x-linked cleft palate and ankyloglossia.
  • Bilateral Renal Agenesis

    a congenital abnormality characterized by the absence of both kidneys.
  • Renal Agenesis

    a congenital abnormality characterized by the absence of one or both kidneys.
  • Unilateral Renal Agenesis|Congenital Single Kidney|Congenital Solitary Kidney|Congenital Solitary Kidney

    a congenital abnormality characterized by the presence of only one kidney.

These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Present on Admission (POA)

Q35.9 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.

Patient Education


Cleft Lip and Palate

Cleft lip and cleft palate are birth defects that occur when a baby's lip or mouth do not form properly. They happen early during pregnancy. A baby can have a cleft lip, a cleft palate, or both.

A cleft lip happens if the tissue that makes up the lip does not join completely before birth. This causes an opening in the upper lip. The opening can be a small slit or a large opening that goes through the lip into the nose. It can be on one or both sides of the lip or, rarely, in the middle of the lip.

Children with a cleft lip also can have a cleft palate. The roof of the mouth is called the "palate." With a cleft palate, the tissue that makes up the roof of the mouth does not join correctly. Babies may have both the front and back parts of the palate open, or they may have only one part open.

Children with a cleft lip or a cleft palate often have problems with feeding and talking. They also might have ear infections, hearing loss, and problems with their teeth.

Often, surgery can close the lip and palate. Cleft lip surgery is usually done before age 12 months, and cleft palate surgery is done before 18 months. Many children have other complications. They may need additional surgeries, dental and orthodontic care, and speech therapy as they get older. With treatment, most children with clefts do well and lead a healthy life.
