Bronchiectasis — VA Diagnostic Code 6601
Respiratory
Diagnostic code
6601
38 CFR § 4.97 lists Diagnostic Code 6601 as “Bronchiectasis.” The percentage lines are 100, 60, 30, and 10. A further line says to rate according to pulmonary impairment as for chronic bronchitis (DC 6600). The note defines an incapacitating episode as one that requires bedrest and treatment by a physician. Section 3.309(a) lists “Bronchiectasis” as a chronic disease. Section 3.307(a)(3) uses one year for that group, and it does not give bronchiectasis the longer periods it names for Hansen's disease, tuberculosis, and multiple sclerosis.

| 10 | Intermittent productive cough with acute infection requiring a course of antibiotics at least twice a year |
| — | Or rate according to pulmonary impairment as for chronic bronchitis (DC 6600). |
Note: An incapacitating episode is one that requires bedrest and treatment by a physician.
DC 6601 does not print a 0 percent line. 38 CFR § 4.31 says: “In every instance where the schedule does not provide a zero percent evaluation for a diagnostic code, a zero percent evaluation shall be assigned when the requirements for a compensable evaluation are not met.” 38 CFR § 4.7 assigns the higher rating when the disability picture more nearly approximates the criteria required for that rating. Otherwise, the lower rating will be assigned. 38 CFR § 4.6 requires each element affecting the evidence to be studied so that decisions will be equitable and just.
38 CFR § 4.96(a) says: “Ratings under diagnostic codes 6600 through 6817 and 6822 through 6847 will not be combined with each other.” It also says: “A single rating will be assigned under the diagnostic code which reflects the predominant disability with elevation to the next higher evaluation where the severity of the overall disability warrants such elevation.” DC 6601 is inside 6600 through 6817. Paragraph (d) names diagnostic codes 6600, 6603, 6604, 6825-6833, and 6840-6845. That list does not include DC 6601. If the “or rate” line is used, the chronic-bronchitis criteria are DC 6600, and paragraph (d) does name 6600.

What the words mean in your records
Incapacitating episode, and the word bedrest
The note says an incapacitating episode is one that requires bedrest and treatment by a physician. The schedule prints “bedrest” as one word. The 100, 60, and 30 percent lines count weeks of those episodes per year. The 10 percent line does not use the words “incapacitating episode.”
The 60 percent “or;”
The 60 percent cell is one sentence joined by “or;”. One side is incapacitating episodes of four to six weeks total duration per year. The other side is near constant findings of cough with purulent sputum associated with anorexia, weight loss, and frank hemoptysis and requiring antibiotic usage almost continuously. “Almost continuously” is on that 60 percent side. It is not a separate 100 percent line.
Or rate as chronic bronchitis
The last line is not a percentage. It says to rate according to pulmonary impairment as for chronic bronchitis (DC 6600). This page does not restate the DC 6600 spirometry lines. 38 CFR § 4.14 says the evaluation of the same disability under various diagnoses is to be avoided. Section 4.96(a) already says those respiratory codes are not combined with each other.
When two evaluations are close
38 CFR § 4.7 assigns the higher rating when the disability picture more nearly approximates the criteria required for that rating. Otherwise, the lower rating will be assigned. 38 CFR § 4.6 requires each element affecting the evidence to be studied so that decisions will be equitable and just.
Evidence that speaks to each level
100, 60, or 30 — episodes
What the rater needs to see. Total duration, in weeks per year, of incapacitating episodes of infection. The note requires bedrest and treatment by a physician for that word to apply.
Where that usually lives. Treatment notes that record bedrest and a physician’s treatment, and the dates that add up to the weeks on the line.
60 — near constant findings
What the rater needs to see. The other side of the 60 percent cell: near constant cough with purulent sputum associated with anorexia, weight loss, and frank hemoptysis, and antibiotic usage almost continuously.
Where that usually lives. The respiratory examination, the sputum description, weight, and the antibiotic record.
30 or 10 — cough and antibiotics
What the rater needs to see. For 30 percent, daily productive cough with sputum that is at times purulent or blood-tinged, and prolonged antibiotic usage (lasting four to six weeks) more than twice a year, or episodes of two to four weeks. For 10 percent, intermittent productive cough with acute infection requiring a course of antibiotics at least twice a year.
Where that usually lives. The examination and the antibiotic courses, including how long each course lasted.
VA’s public DBQ list, checked October 5, 2026, names “Respiratory Conditions (other than tuberculosis and sleep apnea)” under Respiratory. The file is Respiratory Conditions (other than tuberculosis and sleep apnea).
The exam form
DC 6601’s lines are the episode and cough percentages, the instruction to rate pulmonary impairment as chronic bronchitis, and the bedrest note. This page does not say the form replaces that text.
Related codes and how they interact
Chronic bronchitis is the “or rate” code, not a second percentage
DC 6600 is the code named in the last line of DC 6601. Section 4.96(a) does not combine DC 6600 and DC 6601. Section 4.96(d) applies its pulmonary-function rules to DC 6600 and does not list DC 6601.
Secondary conditions and presumptions
38 CFR § 3.309(a) lists “Bronchiectasis.” The schedule title is the same word. 38 CFR § 3.307(a)(3) says the disease must have become manifest to a degree of 10 percent or more within 1 year (for Hansen's disease (leprosy) and tuberculosis, within 3 years; multiple sclerosis, within 7 years) from the date of separation from service as specified in paragraph (a)(2). Paragraph (a)(1) requires 90 days or more during a war period or after December 31, 1946, for the chronic-disease group. 38 CFR § 3.309(a) says the listed diseases shall be granted service connection if manifested to a compensable degree within those time limits, provided the rebuttable presumption provisions of § 3.307 are also satisfied. Paragraph (a) of § 3.307 also says no condition other than one listed in § 3.309(a) will be considered chronic. Bronchiectasis is not one of the three diseases paragraph (a)(3) names for a longer period.
38 U.S.C. § 1120(b), read on the Legal Information Institute page on 2026-10-05, does not use the word “bronchiectasis.” It does list chronic bronchitis, chronic obstructive pulmonary disease, emphysema, interstitial lung disease, pleuritis, pulmonary fibrosis, and sarcoidosis, among other diseases. The 2026-10-01 text of 38 CFR § 3.309(e) does not name it. 38 CFR § 3.320 does not name it. 38 CFR § 3.320b does not name it. 38 CFR § 3.316 does not name it. 38 CFR § 3.309(f) does not name it. 38 CFR § 3.309(d) does not name it.
Section 3.309(b) does not name bronchiectasis. Section 3.309(c) does not name it. Section 3.317(c)(2) does not name it.
A separate question, when a presumption does not decide it, is a medical question on the facts under 38 CFR § 3.310. Paragraph (a) covers disability proximately due to or the result of a service-connected disease or injury. Paragraph (b) covers increase in severity and requires a medical baseline.
Short answers
What is the VA rating for DC 6601?
Under 38 CFR § 4.97, bronchiectasis is rated 100, 60, 30, or 10 percent on the infection-episode and cough lines, or according to pulmonary impairment as for chronic bronchitis (DC 6600). The code does not print a 0 percent line. Education only. VA decides on the evidence.
Does the one-year chronic-disease rule apply to bronchiectasis?
Section 3.309(a) lists bronchiectasis. Section 3.307(a)(3) requires the disease to become manifest to a degree of 10 percent or more within 1 year from separation, and it does not give bronchiectasis the 3-year or 7-year periods named in that sentence.
FAQ
How does VA rate bronchiectasis under DC 6601?
Incapacitating episodes of infection of at least six weeks total duration per year are 100 percent. Four to six weeks, or the near-constant cough findings with antibiotic usage almost continuously, are 60 percent. Two to four weeks, or daily productive cough with prolonged antibiotics more than twice a year, are 30 percent. Intermittent productive cough with a course of antibiotics at least twice a year is 10 percent. The schedule also says to rate pulmonary impairment as chronic bronchitis under DC 6600. An incapacitating episode requires bedrest and treatment by a physician. Education only.
Is bronchiectasis a chronic disease under § 3.309(a)?
Yes. Section 3.309(a) lists bronchiectasis. Section 3.307(a)(3) requires manifestation to a degree of 10 percent or more within 1 year from the date of separation, unless the disease is Hansen's disease, tuberculosis, or multiple sclerosis. Bronchiectasis is not one of those three.
Is bronchiectasis on the burn-pit list in § 3.320 or § 1120?
Section 3.320 does not name bronchiectasis. The enumerated list in 38 U.S.C. § 1120(b), read on October 5, 2026, does not use that word. Section 3.309(e) does not name it. Section 3.316 names a chronic form of bronchitis, not bronchiectasis.
