Code Classification

  • Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified
    (R00–R99)
    • Abnormal findings on examination of other body fluids, substances and tissues, without diagnosis
      (R83-R89)
      • Abnormal findings in specimens from other organs, systems and tissues
        (R89)

R89.6 is a billable diagnosis code used to specify a medical diagnosis of abnormal cytological findings in specimens from other organs, systems and tissues. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

According to ICD-10-CM guidelines this code should not to be used as a principal diagnosis code when a related definitive diagnosis has been established.

Clinical Classification

Clinical Information

  • DNA Mismatch Repair

    a dna repair pathway involved in correction of errors introduced during dna replication when an incorrect base, which cannot form hydrogen bonds with the corresponding base in the parent strand, is incorporated into the daughter strand. excinucleases recognize the base pair mismatch and cause a segment of polynucleotide chain to be excised from the daughter strand, thereby removing the mismatched base. (from oxford dictionary of biochemistry and molecular biology, 2001)
  • MutS DNA Mismatch-Binding Protein

    a methyl-directed mismatch dna repair protein that has weak atpase activity. muts was originally described in escherichia coli.
  • DNA End-Joining Repair

    the repair of double-strand dna breaks by rejoining the broken ends of dna to each other directly.
  • DNA Repair

    the reconstruction of a continuous two-stranded dna molecule without mismatch from a molecule which contained damaged regions. the major repair mechanisms are excision repair, in which defective regions in one strand are excised and resynthesized using the complementary base pairing information in the intact strand; photoreactivation repair, in which the lethal and mutagenic effects of ultraviolet light are eliminated; and post-replication repair, in which the primary lesions are not repaired, but the gaps in one daughter duplex are filled in by incorporation of portions of the other (undamaged) daughter duplex. excision repair and post-replication repair are sometimes referred to as "dark repair" because they do not require light.
  • DNA Repair Enzymes

    enzymes that are involved in the reconstruction of a continuous two-stranded dna molecule without mismatch from a molecule, which contained damaged regions.
  • DNA Repair-Deficiency Disorders

    disorders resulting from defective dna repair processes or the associated cellular responses to dna damage.
  • O(6)-Methylguanine-DNA Methyltransferase

    an enzyme that transfers methyl groups from o(6)-methylguanine, and other methylated moieties of dna, to a cysteine residue in itself, thus repairing alkylated dna in a single-step reaction. ec 2.1.1.63.
  • Rad52 DNA Repair and Recombination Protein

    a dna-binding protein that mediates dna repair of double strand breaks, and homologous recombination.
  • Recombinational DNA Repair

    repair of dna damage by exchange of dna between matching sequences, usually between the allelic dna (alleles) of sister chromatids.
  • DNA

    a deoxyribonucleotide polymer that is the primary genetic material of all cells. eukaryotic and prokaryotic organisms normally contain dna in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. dna, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
