Let’s be sincere: ICD-10 coding doesn’t make for probably the most riveting studying. However as we get nearer to the launch of ICD-10, it’s changing into crucial that you simply perceive the codes you might be more than likely to come across in order that your documentation consists of the small print essential for correct code choice and reimbursement. This installment in our ICD-10 collection addresses frequent gastrointestinal (GI) codes. (See the collection overview.)

To know the required documentation and coding for GI issues in ICD-10, it is smart for main care physicians to consider their sufferers as belonging to considered one of two teams: 1) these with a identified prognosis or 2) these presenting with indicators or signs previous to a documented prognosis. Let’s handle the latter group first.

Indicators and signs involving the digestive system and stomach

ICD-10 provides the next recommendation about when to make use of signal and symptom codes: “Whereas particular prognosis codes needs to be reported when they’re supported by the accessible medical file documentation and medical data of the affected person’s well being situation, there are cases when indicators/signs or unspecified codes are one of the best decisions for precisely reflecting the well being care encounter. … If a definitive prognosis has not been established by the tip of the encounter, it’s applicable to report codes for indicators and/or signs in lieu of a definitive prognosis.” (For extra on this matter, see “ICD-10 Coding for the Undiagnosed Downside,” FPM, Might/June 2014.)

COMMON GI ICD-10 CODES

This text incorporates a number of code lists and tables, which can be found right here for obtain as a single useful resource.

Though indicators and signs documented throughout an workplace go to might or might not end in a closing prognosis of a GI dysfunction, the associated codes are grouped right into a subsection of Chapter 18 titled “Signs and indicators involving the digestive system and stomach,” codes R10–R19.

When utilizing these codes, preserve these three concerns in thoughts:

  • First, a notice of warning: The codes for indicators and signs involving the stomach observe a sequential sample for tenderness, mass, and rigidity – R10.811, R10.812, R10.813, and so on. Nonetheless, the sample doesn’t observe for ache. (See “Belly and pelvic ache codes.”)

  • Second, a notice of frustration: There aren’t any mixture codes. In case you see a affected person with belly ache, tenderness, nausea, and diarrhea, you should both make a prognosis or code all 4 indicators and signs. (See “Different frequent GI symptom codes.”)

  • Third, a notice of clarification: The frequent criticism of diarrhea will be coded as both an indication/symptom (“Diarrhea, unspecified,” R19.7) or a dysfunction (“Useful diarrhea,” K59.1) relying in your affected person’s state of affairs.

Medical state of affairs: A 23-year-old feminine presents to your workplace for an pressing go to. Her historical past consists of onset of generalized belly ache yesterday with nausea however no vomiting. Her final menses was two weeks in the past and regular. She makes use of oral contraceptives for contraception. The ache has now localized to the best decrease quadrant, and she or he has had a pair episodes of diarrhea. On examination, she has a low-grade fever, rebound tenderness over McBurney’s level, and absent bowel sounds. A pelvic examination is adverse. You carry out a white blood cell rely within the workplace that exhibits 14,000 white blood cells per mm3 with a left shift. A urine being pregnant take a look at is adverse. You name the emergency division and organize to have her evaluated there with a CT scan and surgical procedure session.

Deciding easy methods to code this workplace go to presents an attention-grabbing dilemma. You might be pretty sure that your affected person has acute appendicitis, however there could possibly be different etiologies comparable to ovarian torsion or tubal being pregnant. The particular prognosis of acute appendicitis is supported by the medical file however not definitive. Subsequently, per ICD-10 directions, it will be extra applicable to code the indicators and signs than the particular prognosis. You would choose the next codes:

  • R10.823, Rebound belly tenderness, proper decrease quadrant,

  • R11.0, Nausea with out vomiting,

  • R19.7, Diarrhea, unspecified,

  • R19.11, Absent bowel sounds,

  • D72.820, Lymphocytosis (symptomatic).

Particular ailments of the digestive system

Chapter 11 of the ICD-10 code ebook is dedicated to ailments of the digestive system (K00-K95). Let’s discover a few of the diagnoses you are more likely to see in main care.

Esophagitis. The vital factor to notice about this part is when to make use of “different” and when to make use of “unspecified.” Contemplate the next codes:

  • K20.0, Eosinophilic esophagitis,

  • K20.8, Different esophagitis,

  • K20.9, Esophagitis, unspecified.

If the esophagitis has beforehand been decided to be eosinophilic, then clearly you’ll use the K20.0 code. Nonetheless, the “different” code just isn’t for all different causes of esophagitis however is used when the data within the medical file supplies particulars of one other particular prognosis for which a selected code doesn’t exist. The “unspecified” code is used when the data within the medical file is inadequate to assign a extra particular code. The latter state of affairs is extra doubtless with esophagitis.

Simply while you assume it’s clear when to make use of “different” and “unspecified,” ICD-10 throws you a curve ball: “For these classes for which an unspecified code just isn’t offered, the ‘different specified’ code might characterize each ‘different’ and ‘unspecified.’”

Gastro-esophageal reflux illness (GERD). There are solely two codes for this situation:

  • K21.0, Gastro-esophageal reflux illness with esophagitis,

  • K21.9, Gastro-esophageal reflux illness with out esophagitis.

Reflux esophagitis codes to “with esophagitis,” and esophageal reflux codes to “with out esophagitis.” In case you solely put GERD in your documentation, it needs to be thought of NOS (not in any other case specified) and default to K21.9.

Barrett’s esophagus. While you’re following a affected person after a definitive prognosis has been established by biopsy, you’ll use the next codes:

  • K22.70, Barrett’s esophagus with out dysplasia,

  • K22.710, Barrett’s esophagus with low-grade dysplasia,

  • K22.711, Barrett’s esophagus with high-grade dysplasia,

  • K22.719, Barrett’s esophagus with unspecified dysplasia.

It is very important notice that when the take a look at outcomes use a time period like “according to,” this isn’t thought of a definitive prognosis. Sadly, this time period seems on many pathology reviews.

Ulcer illness. There are separate code teams for esophagus (K22.1), gastric (K25), duodenal (K26), unspecified peptic (K27), and gastrojejunal ulcer (K28). Every group has subcodes for acute or continual, and every subgroup additional stratifies to with or with out hemorrhage or perforation, neither, or each. If you’re evaluating a affected person previous to endoscopy, you must code the situation of hematemesis (K92.0) reasonably than use an unspecified peptic ulcer code. Solely about 50 % of acute higher GI bleeding is the results of peptic ulcer illness.1 ICD-10 has decided that hematemesis is a illness, not an indication or symptom.

Hernias. For unclear causes, though ICD-10 goes to nice lengths to incorporate laterality (left, proper) in each orthopedic code, it doesn’t permit you to designate which aspect of the physique has a unilateral hernia. Hernias are categorised by location – inguinal (K40), femoral (K41), umbilical (K42), ventral (K43), diaphragmatic (K44), different (K45), and unspecified (K46). Every group has extra codes for with or with out obstruction, with or with out gangrene, and recurrent. ICD-10 additionally consists of the choice “not specified as recurrent,” versus first prevalence, however it differentiates this just for inguinal and femoral hernias. So, should you solely doc the situation of the hernia within the medical file, your coder (if in case you have one) can contemplate that shorthand for NOS (not in any other case specified) and default to the “with out obstruction or gangrene, not specified as recurrent” code.

Most main care physicians will use solely 4 of the 45 hernia codes:

  • K40.20, Bilateral inguinal hernia, with out obstruction or gangrene, not specified as recurrent,

  • K40.90, Unilateral inguinal hernia, with out obstruction or gangrene, not specified as recurrent,

  • K42.9, Umbilical hernia with out obstruction or gangrene,

  • K43.2, Incisional hernia with out obstruction or gangrene.

Noninfective enteritis and colitis. This grouping is proscribed to Crohn’s illness, ulcerative colitis, and non-specific colitis. (Irritable bowel syndrome will come later.) Every of the inflammatory bowel issues consists of particular codes for with and with out problems in addition to the kind of complication (bleeding, obstruction, fistula, or abscess). Every can also be stratified by location. Crohn’s consists of the small gut, massive gut, each small and huge gut, and unspecified. Ulcerative colitis consists of pancolitis, proctitis, and rectosigmoiditis.

The “with out problems” codes are listed under:

  • K50.00, Crohn’s illness of small gut with out problems,

  • K50.10, Crohn’s illness of enormous gut with out problems,

  • K50.80, Crohn’s illness of each small and huge gut with out problems,

  • K51.00, Ulcerative pancolitis with out problems,

  • K51.30, Ulcerative rectosigmoiditis with out problems.

Diverticular illness. The acute diverticulitis codes can be used sparingly within the main care setting. While you see a person with identified diverticular illness who presents with basic diverticulitis findings, chances are you’ll select to empirically deal with the affected person and use signal and symptom codes or a diverticulitis code comparable to the next:

  • K57.30, Diverticulosis of enormous gut with out perforation or abscess with out bleeding,

  • K57.32, Diverticulitis of enormous gut with out perforation or abscess with out bleeding.

Medical state of affairs: A 57-year-old male presents with belly ache for 2 days. He has no urge for food, and the ache is generally within the left decrease stomach. Important indicators doc a temperature of 101.7°F and a gentle tachycardia (105 beats per minute). He tells you he usually has a bowel motion each morning however has not had one for the previous two days. He had an analogous episode two years in the past that you simply empirically handled with antibiotics and resolved. He underwent a colonoscopy that confirmed important diverticulosis. Biopsies had been adverse for inflammatory bowel illness. At this time’s bodily examination exhibits left lower-abdomen tenderness with out rebound. Rectal examination exhibits no mass and minimal stool, which is heme adverse. Bowel sounds are absent. His white blood cell rely within the workplace is 14,000 white blood cells per mm3 with a left shift. You establish that the more than likely prognosis is acute diverticulitis with out hemorrhage or obstruction. You determine to deal with with a liquid weight-reduction plan and broad-spectrum oral antibiotics. You talk about the necessity for pressing reevaluation with any worsening of the signs and organize a follow-up go to within the workplace in 24 to 48 hours.

Not like the appendix instance mentioned earlier, this prognosis doesn’t require extra imaging and is usually made primarily based on the historical past and examination. Subsequently, given the identified historical past of diverticulosis, the previous doubtless prognosis of diverticulitis, and the basic presentation, it will be applicable to diagnose the affected person with acute diverticulitis, K57.32.

It additionally could be appropriate to code this primarily based on the indicators and signs:

  • R10.32, Left lower-quadrant ache,

  • R10.814, Left lower-quadrant tenderness,

  • R19.11, Absent bowel sounds,

  • D72.820, Lymphocytosis.

Irritable bowel syndrome (IBS). Diagnosing IBS will be difficult as a result of there is no such thing as a standardized definition of this situation. Many physicians observe the Rome III diagnostic standards for outlining when a person needs to be identified with IBS or different purposeful gastrointestinal issues,2 however the World Well being Group/ICD-10 doesn’t reference these standards. The World Well being Group additionally has not acknowledged IBS-C (irritable bowel syndrome with constipation) as a stand-alone prognosis, so ICD-10 requires use of each an IBS code and a constipation code. Nonetheless, there are IBS codes for with and with out diarrhea. (See “IBS-related codes.”)

Hemorrhoids. These codes are pretty easy. Simply do not forget that the diploma of hemorrhoidal illness is most frequently established by historical past reasonably than examination.

  • K64.0, First diploma hemorrhoids, with out prolapse exterior of anal canal,

  • K64.1, Second diploma, prolapse with straining however retract spontaneously,

  • K64.2, Third diploma, prolapse with straining and require handbook alternative,

  • K64.3, Fourth diploma, prolapsed, can’t be manually changed.

Miscellaneous. Lastly, there are a number of frequent codes used for different parts of the digestive system exterior the alimentary tract:

  • K70.30, Alcoholic cirrhosis of the liver with out ascites,

  • K76.0, Fatty liver, not elsewhere categorised (consists of nonalcoholic fatty liver illness; excludes nonalcoholic steatohepatitis, K75.81),

  • K80.00, Calculus of gallbladder with acute cholecystitis with out obstruction,

  • K80.2, Calculus of gallbladder with out cholecystitis,

  • K81.0, Acute cholecystitis,

  • K85.0, Idiopathic acute pancreatitis,

  • K85.2, Alcohol induced acute pancreatitis,

  • K90.0, Celiac illness.

Breaking it down

Keep in mind that the codes mentioned above, these most typical in main care, are solely a small fraction of the codes used for the digestive system. ICD-10 has over 700 ICD-10 codes within the chapter dedicated to ailments of the digestive system and at the least an extra 80 within the indicators and signs chapter.

Additionally, do not forget that the coding situations introduced on this article are particular to the out-patient setting, the place unsure diagnoses usually are coded with indicators and signs codes. For inpatient care at short-term, acute, long-term, and psychiatric hospitals, an unsure prognosis is allowed. Per ICD-10, Part II-H, “If the prognosis documented on the time of discharge is certified as ‘possible,’ ‘suspected,’ ‘doubtless,’ ‘questionable,’ ‘doable,’ or ‘nonetheless to be dominated out,’ or different related phrases indicating uncertainty, code the situation as if it existed or was established. The idea for these pointers are the diagnostic workup, preparations for additional workup or remark, and preliminary therapeutic method that correspond most carefully with the established prognosis.”

If all of this leaves you feeling annoyed by the ICD-10 guidelines, relaxation assured that you simply’re not alone. The creator agrees that this coding is K62.9 – ache, anal. Nonetheless, by orienting your self to the brand new codes, you will be higher ready when the code set launches.
