Range Overview

high priority

The ICD-10 code range N70-N77 pertains to inflammatory diseases of female pelvic organs. These codes are used to classify and document various conditions such as salpingitis and oophoritis, inflammatory diseases of the uterus, and other inflammatory diseases of the female pelvic organs. The codes are detailed and specific, allowing for precise documentation of the condition's location, cause, and severity.

Key Usage Points:

  • N70 codes are used for salpingitis and oophoritis, with subcodes specifying acute, chronic, or unspecified conditions.
  • N71 codes pertain to inflammatory diseases of the uterus, excluding the cervix.
  • N72 is used for inflammatory diseases of the cervix uteri.
  • N73-N76 codes cover other female pelvic inflammatory diseases, including noninfective disorders.
  • N77* codes, asterisked codes, are used to indicate conditions in N70-N76 as complications of surgery, or of other diseases classified elsewhere.

Coding Guidelines

When to Use:

  • When a patient presents with symptoms of pelvic inflammatory disease (PID) and is diagnosed accordingly.
  • When a patient has a chronic inflammatory condition of the uterus, such as endometritis.
  • When a patient has an inflammatory disease of the cervix, such as cervicitis.
  • When a patient has an inflammatory disease of the female pelvic organs due to a surgical procedure.
  • When a patient has an inflammatory disease of the female pelvic organs as a complication of other diseases.

When NOT to Use:

  • When a patient has a non-inflammatory condition of the female pelvic organs.
  • When a patient has an inflammatory disease of the male genital organs.
  • When a patient has an inflammatory disease of the female breast.
  • When a patient has a sexually transmitted infection without pelvic inflammation.
  • When a patient has pelvic inflammatory disease (PID) without a confirmed diagnosis.

Code Exclusions

Always verify exclusions against the patient's medical record and the latest ICD-10 guidelines.

Documentation Requirements

Documentation for N70-N77 codes should be thorough and specific, detailing the location, cause, and severity of the condition. It should also include the patient's symptoms, diagnostic tests, and treatment plan.

Clinical Information:

  • Detailed description of the patient's symptoms
  • Specific diagnosis of the inflammatory condition
  • Location of the inflammation
  • Cause of the inflammation, if known
  • Severity of the condition

Supporting Evidence:

  • Results of diagnostic tests
  • Notes from physical examinations
  • Imaging reports, if applicable
  • Treatment plan and patient's response to treatment
Good Documentation Example:

Patient presents with lower abdominal pain, fever, and abnormal vaginal discharge. Diagnosed with acute salpingitis and oophoritis. Ultrasound confirms inflammation of fallopian tubes and ovaries. Started on antibiotics.

Poor Documentation Example:

Patient has pelvic pain. Started on antibiotics.

Common Documentation Errors:

  • Not specifying the location of the inflammation
  • Not documenting the cause of the inflammation
  • Not detailing the severity of the condition
  • Not including supporting evidence such as diagnostic test results

Coding Complexity

Medium
Complexity Rating

Coding for inflammatory diseases of female pelvic organs can be complex due to the need to specify the location, cause, and severity of the condition. Additionally, the use of asterisked codes for complications adds another layer of complexity.

Key Factors:
  • Determining the specific location of the inflammation
  • Identifying the cause of the inflammation
  • Assessing the severity of the condition
  • Navigating the subcodes for specific conditions
  • Identifying complications of surgery or other diseases

Specialty Focus

These codes are primarily used by gynecologists, obstetricians, and emergency medicine physicians. They are also relevant for general practitioners and internists who may encounter these conditions.

Clinical Scenarios:
  • A 25-year-old woman presents with lower abdominal pain, fever, and abnormal vaginal discharge. She is diagnosed with acute salpingitis and oophoritis.
  • A 40-year-old woman has chronic pelvic pain and is diagnosed with chronic noninfective salpingitis and oophoritis.
  • A 30-year-old woman presents with postpartum fever and is diagnosed with endometritis.
  • A 35-year-old woman presents with abnormal vaginal bleeding and is diagnosed with cervicitis.
  • A 45-year-old woman has pelvic pain following a hysterectomy and is diagnosed with postoperative pelvic peritonitis.

Frequently Asked Questions

Can N70-N77 codes be used for male patients?

No, these codes are specific to inflammatory diseases of female pelvic organs. For male patients, other code ranges would be applicable.

What is the significance of the asterisk in N77* codes?

The asterisk in N77* codes indicates that these codes are used to document conditions in N70-N76 as complications of surgery, or of other diseases classified elsewhere.
