Covid-19 and Mucormycosis- Appropriate Medical Coding for Data Analytics and Statistics-MEDESUN Coding Academy


Healthcare infrastructure and all related support activities has been stretched globally beyond comprehension owing to COVID 19. Trained resources to manage healthcare has been in short supply and this scenario has affected even backend operations, which is a very vital component to ensure seamless operations of healthcare chain.

Even while all-out effort is being made to scramble for solutions, outsourcing backend work is gaining prominence.  This is where the relevance of Health Information Management (HIM) assumes great importance.

The Heath Information management industry helps the healthcare sector in many ways. It keeps a constant check on whether patients are served in the right way. It sees to it that there are no medical mistakes, high drug safety, no fragmented delivery systems and high quality of information system is maintained.

Medical Coding and capturing the required data elements are key for HIM.

Medesun, Pioneers in medial coding in India, provides training, consulting for HIM champions, prospective HIM fellows.

COVID-19 and Mucormycosis Medical Coding-2021

Code U07.1, COVID-19, is assigned only if the provider documentation either specifically documents a confirmed diagnosis of the COVID-19

Pneumonia due to COVID-19: Assign codes U07.1 and J12.89, Other viral pneumonia.

Acute bronchitis due to COVID-19: Assign codes U07.1 and J20.8, Acute bronchitis due to other specified organisms.

Bronchitis not otherwise specified (NOS) due to COVID-19: Assign codes U07.1 and J40, Bronchitis, not specified as acute or chronic.

COVID-19 with a lower respiratory infection, not otherwise specified (NOS), or an acute respiratory infection, NOS: Assign codes U07.1 and J22, Unspecified acute lower respiratory infection.

COVID-19 associated with a respiratory infection, NOS: Assign codes U07.1and J98.8, Other specified respiratory disorders.

Acute respiratory distress syndrome (ARDS) due to COVID-19: Assign codes U07.1 and J80, Acute respiratory distress syndrome.

Patient is admitted with pneumonia due to COVID-19, which then progresses to viral sepsis (not present on admission): Assign code U07.1 as the principal diagnosis, followed by the codes for the viral sepsis (A41.89) and viral pneumonia (J12.89).

Patient is admitted with sepsis due to COVID-19 pneumonia, and the sepsis meets the definition of principal diagnosis: Assign the code for viral sepsis (A41.89) as the principal diagnosis followed by codes U07.1 and J12.89 as secondary diagnoses.

Asymptomatic patient tests positive for COVID-19: Assign code U07.1. Although the individual is asymptomatic, the individual has tested positive and is considered to have COVID-19.

Pregnant patient admitted with mild COVID-19 and acute bronchitis: Assign the appropriate code from subcategory O98.51, Other viral diseases complicating pregnancy, as the first-listed diagnosis, followed by codes U07.1 and J20.8 and an additional code for the number of weeks of gestation.

Newborn tests positive for COVID-19 during the birth admission without documentation specifying the type of transmission: Assign first the appropriate code from category Z38, Liveborn infants according to place of birth and type of delivery, as the principal diagnosis, followed by code U07.1.

Patient is admitted with viral enteritis due to COVID-19: Assign code U07.1 as the principal diagnosis, followed by the code for the viral enteritis (A08.39).

Patient status post lung transplant contracts COVID-19: Assign code T86.812, Lung transplant infection, followed by code U07.1.

For asymptomatic individuals with actual or suspected exposure, assign code Z20.828, Contact with and (suspected) exposure to other viral communicable diseases.

Personal History. If a patient has a history of COVID-19, assign code Z86.19, Personal history of other infectious and parasitic diseases.


Mucormycocis-one of the post covid, life threatening complication.

Mucormycosis is not black in colour, Mucormycosis causes tissue blackening by devitalizing its blood supply and this black appearance. Infection due to a fungus of the zygomycota phylum.

The disease typically involves the rhino-facial-cranial area, lungs, gastrointestinal tract, skin, or less commonly other organ systems.

Mucormycocis invades the blood vessels and cause embolization and there by necrosis of tissues.

The main causes are uncontrolled diabetes and immunosuppression

Unacceptably high mortality`

ICD-10-CM Codes:

B46 Zygomycosis

  • 0 Pulmonary mucormycosis
  • 1 Rhinocerebral mucormycosis
  • 2 Gastrointestinal mucormycosis
  • 3 Cutaneous mucormycosis
  • 4 Disseminated mucormycosis
  • 5 Mucormycosis, unspecified
  • 8 Other zygomycoses
  • 9 Zygomycosis, unspecified

Good diabetes care and prediabetes care are critical to avoid contracting the infection. Reversal of underlying predisposing factor, surgical debridement of infected foci and antifungal therapy.

Medesun has structured online training that offers comprehensive HIM course aimed at creating a talent pool of skilled healthcare coders. The course includes:
